TDK B32354S series capacitors

TDK Corporation (TSE:6762) has added the B32354S series to its portfolio of metalized polypropylene (MKP) capacitors for filter applications. The new devices, which feature a 4-pin design and a pitch of 52.5mm, are rated for VRMS of 27V AC or 350V AC and cover a capacitance range from 10μF to 40μF. The maximum operating temperature is 85°C. The new AC film capacitors feature compact dimensions, a high AC load capacity, and optimized dielectric strength. They impress with their high resistance to harsh operating conditions such as high humidity. By means of a THB test (Grade III test B) according to IEC 60384-14:2013/AMD1:2016 with an operating temperature of 85°C and a relative humidity of 85percent at applied nominal voltage for 1,000hours, reliability even under challenging external influences was proven. Certified to IEC 61071, the capacitors offer a life of at least 100,000hours and a very low failure rate of less than 5FIT. With its integrated safety function, the new series meets the highest safety level (10,000AFC) and is UL 810 approved. The capacitors carry the CE mark, and the housing and potting material comply with UL 94V-0. Typical applications for the rugged film capacitors include demanding filtering applications such as output filtering of frequency converters for drives, uninterruptible power supplies (UPS), and photovoltaic inverters.
