Qing Quan Electronics - aluminum electrolytic capacitor R & D and production experts! The relationship between the actual life of aluminum electrolytic capacitors and electrolytic capacitors nominal life of the electrical characteristics change over time and the relationship between temperature experimentally in line with the formula. Alicante Vilnius chemical description of this relationship with the temperature and the chemical reaction rate of reaction is similar to the laws, it was known as temperature and aluminum electrolytic capacitor life of Alicante Vilnius rule. Where L0: the maximum temperature of the active life (hrs) LX: using temperature calculation life (hrs) T0: maximum use temperature of the product (℃) TX: temperature (℃) A: life expectancy rate or said temperature acceleration factor Here, if the maximum working temperature, you can use the temperature acceleration factor A≈2, used to calculate the temperature rise every 10 ℃ have twice the life expectancy rate or called accelerated rate, so using the lower the temperature, the more you can look forward to a long life. Qing Quan Electronics - aluminum electrolytic capacitor R & D and production experts! It features aluminum electrolytic capacitors: Advantages: small size, high capacity, low prices. Disadvantages: large leakage, loss, capacity error, time poor stability, poor insulation quality, the ability to withstand over-voltages worst, easily breakdown, and its capacity, loss of temperature, frequency characteristic is very poor, so in electronic the device can only be used as a rectifier filter, audio bypass or low frequency coupling purposes.
