Cornell Dubilier / Knowles BLS 125°C DC-Link Capacitors
Cornell Dubilier / Knowles BLS 125°C DC-Link Capacitors feature advanced construction and technology to meet the challenges of harsh environments. Rated for up to +125°C, these capacitors undergo 2000 hours of temperature/humidity/bias (THB) testing at +85°C and 85% relative humidity (RH) while operating at rated voltage, ensuring long-term durability and resistance to failure in harsh environments where higher temperatures and moisture levels can impact component integrity. The capacitors are qualified to automotive-grade electrical and mechanical testing per the AEC-Q200 standard. Cornell Dubilier / Knowles BLS 125°C DC-Link Capacitors feature robust construction and are suitable for both horizontal and vertical board mounting. The BLS series is ideal for DC filtering and DC link applications where reliable performance under variable environmental conditions is crucial.
