Features and sound performance of fever capacitors

1. German WIMA capacitor: The characteristics are fast speed, low loss, sound quality is naturally balanced, the sound quality is cold, suitable for a variety of listening requirements. There are many varieties of WIMA, the best is Black Box, followed by MKP MKS, the other is German ERO, the characteristics are similar to WIMA, this capacitor has more disassembled products on the market, and the price is not too expensive.



2. French SOLEN capacitor: rich and soft tone. Some people like it to be full of music, some people think its tone is too dim, in short, it has a strong personality. For hot devices, SOLEN is suitable for supplementation, but some amplifiers may not be suitable. There are two kinds of SOLEN brand, one is big S SOLEM, and it is marked with France (France); the other is SCR SOLEN, this kind of capacitor tgs (loss angle) is particularly low, worthy of the title of the world's polypropylene ace capacitor.



3. Black Gate F (black King Kong) capacitor: The sound is mellow, which is very helpful to increase the musical performance of the equipment, but those who like the beautiful music (commonly known as Lengyan) do not consider it, suitable for coupling.



4. Japan ELNA capacitors: materials are used at all costs, the pins are made of oxygen-free copper, the wires are thick, the aluminum foil is made of ceramic particles, and the appearance is larger. The most prominent performance during testing is that the loss angle tgs is particularly low. ELNA coupling dedicated capacitors The tgs of 22uF / 50V is as low as 0.007, which is no different from the famous polypropylene ace SOLEN. It has several brands, namely For AV-DIO: the sound is sweet, like a young girl; CERAFINE DUOREX: the sound is well-defined, transparent, and the speed is medium; SILMIC: fast and powerful, suitable for expressing modern music. There are ordinary products, customized products and top-grade products on the market, and the price is medium.



5. Japan Chemical (NIPPON) capacitors: The materials and body are the same as ELNA, and the tone performance is quite neutral. This capacitor is marked with AWF, AVF, etc.



6. Matsushita gold word complement capacitors: Although the materials are not very good, the pins do not use oxygen-free copper, and their tgs values ​​are almost the same at 100Hz, so the tone balance is better and there is no choking.



7. Tantalum electrolysis: low leakage and good stability, but it is flexible and weak for coupling high frequency, lacking penetrating power, and better for decoupling.



8. RUBYCON (Ruby) capacitor: This is the most used brand of domestic power amplifiers. It is mainly used in power supply decoupling. It is better for coupling high and low frequencies. Its brand is BLACK GATE, but BLACK GATE is the most counterfeit in the market. Be careful when buying.



9. European and American brands ROE, FRAKO capacitors: have a good sense of music, especially when listening to classical works, the music lines are clear and vivid, which is unmatched by Japanese products.



10. Knack (Nikon) capacitor: a brand with a strong personality, warm tone, cold equipment should be supplemented by knock.



11. RIFA (Australia and Sweden) capacitor: This capacitor is the most suitable for the complementary frequency divider, and has strong penetration power for high frequency.



12, Japan Sanyo (OS-CON) capacitor: This capacitor electrolyte is not liquid or colloidal but solid, its withstand voltage is not high, the highest is only 30V, but used to supplement digital power supply, analog power supply and other occasions where the voltage is not high Still more than enough. The advantage of OS capacitors is good high frequency performance, close to the characteristics of thin film capacitors. Its long life is unmatched by ordinary capacitors. The sound is sweet and very natural.



Tone winner metalized polypropylene MKP audio capacitor



Polypropylene capacitors are a variety developed abroad in the 1960s, and they are favored as soon as they come out. It is one of the excellent types of non-polar organic dielectric film capacitors, which is commonly used in China.



The metallized polypropylene capacitor is a new type of plastic film capacitor that was put into use in the early 1980s. It is expressed by MKP abroad. It is resistant to high temperatures and has a small absorption coefficient. Its capacity and loss tangent tgs change little with temperature and temperature, while the dielectric strength is The temperature rise has increased, which is difficult for other dielectric materials.



The MKP pole piece is formed by evaporating a metal film on the direct polypropylene film, eliminating the gap between the electrode and the film, which greatly enhances the capacity stability. In addition, when the voltage at both ends is too high, the capacitor medium will be partially broken down. The local high temperature makes the thin layer of the adjacent metalized electrode volatilize to achieve self-healing, and will not cause a short circuit between the capacitor pole pieces due to dielectric breakdown.



MKP capacitor is the guarantee of good sound quality of audio equipment. Used for power supply filtering, a 0.1 ~ 0.22uF MKP capacitor is connected in parallel on the large electrolysis, which can filter out the unclean higher harmonics, so that the positioning sense and resolution are higher. It is used for frequency compensation, coupling circuit playback, will Kind and smooth. The bass has good bounce performance and smaller subtle losses. A small coupling MKP capacitor is connected to the input of the power amplifier to ensure good linearity and high conversion rate of the power amplifier. MKP is used on the crossover network. Due to the small leakage loss, the sound stain is reduced. Enhance the control of the speaker.



Polypropylene (MKP), Polystyrene (MKS), Polyterephthalate (MKT) Polycarbonate (MKC), Polyester and other organic thin-film media with the highest capacitance MKP and MKS performance, MKP The electrical parameters such as loss, dielectric absorption, frequency, insulation resistance, etc., MKP temperature intensity is higher than MKS, but its temperature stability is slightly worse than MKS, basically close to MKS. The biggest shortcoming of MKS is poor heat resistance, the limit is only 75 ℃, while MKP reaches 100 ℃.



Tone Winner metalized polypropylene audio capacitors are Hi-Fi high-quality MKP capacitors used in Tone Winner brand karaoke, power amplifier speakers and crossovers exported by Chengdu Yadi Electromechanical Research Institute.



In WIMA, the metallized capacitor with polyethylene film as the medium has a wide range of voltage resistance (50 ~ 630U) and capacity (120pF ~ 10uF).

An anti-theft system is any device or method used to prevent or deter the unauthorized appropriation of items considered valuable. Theft is one of the most common and oldest criminal behaviors specially happened popularly at Telecom base site and power station from ASEAN, Africa and Asia, etc.  Our anti-theft systems via GPS tracking management technology have been evolved to match the introduction of new inventions to stationary batteries and the resulting thief been caught as soon as stealing the batteries.
At present, there are huge number of Telecom base stations all over the world, the vast majority of sites are located in remote areas with any unattended which are stolen seriously. Theft violently destroy the infrastructure of the base station and steal batteries, resulting in serious losses such as communication breaking and stations maintenance. The conventional protective measures, such as iron guardrail, external positioning alarm device, and anti-theft screw, not only are unable to achieve your desired effect, but also have the disadvantages of higher cost, lower battery life and weaker concealment.
Our battery anti-theft solution and Monitoring Tracing system is comprised of GPS module and software operation platform. This equipment includes GPS satellite positioning system and network positioning system, that is GPS+LBS dual intelligent positioning mode. It has the function of satellite positioning, base station locating, remote reset, remote upgrade, fence alarm, tracking replay, battery low voltage alarm, vibration alarm,etc.   
The utility model aims at resolving the problem that an Uninterrupted Power Supply (UPS) storage battery of a field station can not guard against a thief effectively and providing a global position system (GPS) and anti-theft monitoring tracing system for a storage battery. A terminal module is connected with a management platform and mobile phone signals through a mobile communication network. The terminal module comprise a GPS module, a central processing unit (CPU) module connected with a mobile communication network module and a vibration transducer connected with the CPU module.
