Rugged ac filter capacitor of the B32354S3 series

Rugged AC Filter Capacitors Get UL 810 Approval

TDK’s B32354S3 series offers capacitance values of 10 µF to 40 µF, and conforms to the highest safety class.

TDK Corporation has launched a new series of UL 810-approved ac filter capacitors carrying the CE mark. The capacitors of the B32354S3 series are designed for a rated voltage of 350-V ac and are available with capacitance values of 10 µF to 40 µF. The lead spacing is 52.5 mm. Because of the segmented film structure, the new capacitors conform to the highest safety class of UL 810 at the component level.

Owing to their improved protection against moisture, the capacitors pass a temperature, humidity, bias (THB) test at 85°C, 85% relative humidity and applied rated voltage for 1000 hours. The life expectancy of the new series 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.
