UL 810-approved ac filter capacitors are rugged

May 22, 2019  Stephen Law

TDK B32354S3 series of ac filter capacitors are UL 810 approved at the component level and carry the CE mark. Capacitors are designed for a rated voltage of 350Vac and are available with capacitance values of 10µF to 40µF, and a lead spacing of 52.5mm. Because of the segmented film structure, devices conform to the highest safety class of UL 810 at component level. Due to the improved protection against moisture, devices pass a temperature, humidity, bias (THB) test at 85°C, 85% relative humidity and applied rated voltage for 1000 hours. Device’s life expectancy according to IEC 61071 is 100,000 hours. In addition to ac applications, the rugged capacitors are suitable for output filtering of power supplies and inverters.
