Vishay Intertechnology has introduced the F339X2 305VAC series of Automotive Grade X2 electromagnetic interference (EMI) suppression film capacitors for standard across the line applications (50 Hz / 60 Hz). The capacitors are qualified to both AEC-Q200 (rev. D) and IEC 60384-14: 2013 / AMD1: 2016 grade IIB.

To comply with the new humidity grading system defined under IEC 60384-14: 2013 / AMD1: 2016 grade IIB, Vishay BCcomponents F339X2 305VAC series devices withstand temperature humidity bias (THB) testing of 85 °C, 85 % RH for 500 hours at rated voltage with high stability on capacitance and dissipation factors, which translates into greater robustness and longer service life in harsh application conditions.

The devices will serve as EMC filters for automotive and industrial power inverters. The capacitors offer lead pitches of 15mm, 22.5mm, and 27.5mm; capacitance values from 0.1μF to 4.7μF with tolerances down to ± 10%; and a permissible DC voltage of 630V.

The encapsulation of the F339X2 305VAC series consists of a flame-retardant UL-class 94 V-0 plastic case, which is epoxy resin-sealed. The lead (Pb)-free devices are RoHS-compliant.

Samples and production quantities of the new X2 capacitors are available now, with lead times of 17 weeks.
