At present, most of the film capacitors used for DC support of new energy vehicles use high-temperature polyethylene film as the medium, so what advantages do film capacitors have? Huizhou Xintaifeng Capacitor Co., Ltd. will tell you about it.
1. The film capacitor product has good safety, strong overvoltage resistance, good temperature characteristics, and the temperature range of the product can be from -40°C to 105°C;
2. Film capacitors have stable frequency characteristics, good high-frequency characteristics, polarity, can withstand reverse voltage, low ESL, and long service life;
3. Film capacitors have a high rated voltage, no need for series and balancing resistors, low ESR, strong ripple current resistance, and strong surge current resistance.
The electrodes of film capacitors are nanometer-scale metals evaporated on the film. The product has no polarity, so it is very convenient for users, and there is no need to consider the problem of positive and negative electrodes. For electrolytic capacitors, if it exceeds 1.5 When a reverse voltage times Un is applied to the electrolytic capacitor, it will cause a chemical reaction inside the capacitor. If this voltage lasts long enough, the electrolyte will flow out as the internal pressure of the capacitor is released.
The feature that the film is not easy to age determines that the film capacitor has a very long life, especially at the rated voltage and rated temperature, the service life is more than 15000 hours, if the average 30Km/H, then there can be 450000Km in the service life, the service life of the capacitor is for The car's mileage is adequate.
Huizhou Xintaifeng Capacitor Co., Ltd. has production equipment and testing instruments imported from abroad. It has a high degree of automation, advanced production equipment, and perfect testing methods. products and services.
