What problems should be paid attention to when using CBB capacitors?

♦ Never use it when the temperature is too high

The high temperature resistance of high-quality CBB capacitors is 105°C. The high temperature resistance of ordinary CBB capacitors is 85°C. If the circuit board heats up and the heat dissipation is poor, it will seriously affect the service life of the CBB capacitor. The higher the temperature, the shorter the service life will be.

♦ Overcurrent is also the reason why CBB capacitors are easily damaged.

Overcurrent (the current exceeds the rated ripple current), after the applied ripple current exceeds the rated value, it will cause the CBB capacitor body to overheat, reduce the capacity, and shorten the service life.

♦ The working voltage exceeds the rated voltage of the CBB capacitor

When the voltage applied to the capacitor is higher than the rated working voltage, the leakage current of the capacitor will increase, and its electrical and oxygen properties will deteriorate in a short period of time until it is damaged.
