B3291xH EMI Suppression Capacitors

EPCOS / TDK B3291xH EMI Suppression Capacitors are designed for power line filtering of Electromagnetic Interference (EMI) in demanding automotive and industrial applications. These capacitors are THB-tested at 85°C, 85% relative humidity for 1000 hours at 380V (AC) and 1000V (DC). The B3291xH capacitors feature a 15nF to 10μF capacitance range. These capacitors are available in 18mm x 10.5mm x 5mm to 57.5mm x 57mm x 45mm dimensions. The B3291xH capacitors are certified according to ENEC, UL, and CSA standards. Typical applications include the X1 class for interference suppression, across-the-line application, and severe ambient conditions.
