Welcome to the official website of Zhizhong Electronics Co., Ltd.Company focus: Ceramic Capacitor, Monolithic capacitor

Electrolytic capacitors used by capacitor manufacturers for energy-saving lamps are prone to switch breakdown. In addition to strict control of burrs and foil dust during cutting and riveting, it is also due to the application of high ripple current to the capacitor or short-term voltage difference and large charging and discharging. Because the capacitance on the aluminum stem where the negative lead pin is riveted is very low, it is easy to cause the negative electrode to spark and breakdown, so we adopted a small piece of negative electrode aluminum foil with the same specific volume on the negative electrode to increase the capacity.

The products of capacitor manufacturers need to work for a long time at high temperature, and its sealing performance is very important. The use of butyl rubber with high hardness (Shore hardness above 82) does not require a deep waist to achieve good sealing performance; control core The spin-drying after impregnation and the time of exposure to the air keep the electrolyte relatively large in adsorption capacity; a cover is installed above the core vibrating plate on the assembly machine to block the air and the core during production. To avoid the absorption of moisture and impurities in the air; at the same time, the gap between the core and the rubber particles is controlled between 0.2~0.4mm during the assembly process, which is beneficial for the gas in the product to be discharged immediately before sealing, etc. .
In order to improve the reliability of the product, the capacitor manufacturer appropriately increased the aging voltage by 10~20V compared with the original product during aging, and extended the high temperature time from the original 7 hours to 9 hours, which not only effectively reduced the leakage current of the product, but also reached It has an early screening to eliminate defective products.
