Cornell Dubilier / Knowles BLH AEC-Q200 DC-Link Harsh Environment Capacitors
Cornell Dubilier (CDE) BLH AEC-Q200 DC-Link Harsh Environment Capacitors used advanced construction and technology to meet harsh environmental challenges. The BLH Capacitors have been tested for 1500 hours at +85°C with 85% relative humidity and the rated voltage applied (50% greater than competitive THB test life). These board-mounted components offer a high capacitance range, high ripple current, self-healing, and low losses. The BLH AEC-Q200 DC-Link Harsh Environment Capacitors are qualified for automotive-grade electrical and mechanical testing.
