Capacitors designed for demanding automotive applications

Rutronik Elektronische Bauelemente has added the TCQ series conductive polymer chip capacitors from AVX to its portfolio. These robust capacitors are designed for demanding automotive applications. Qualified to the Automotive Electronics Council’s AEC-Q200 specification for passive components, the series meets their challenging 125C lifetime stability test and humidity bias testing at 85C and 85% relative humidity for up to 1,000 hours. Operation temperature ranges from -55C to 125C. The capacitors of this series offer a conductive polymer electrode and have a benign failure mode under recommended use conditions. They are lead-free and RoHS compliant. They are currently available in three case sizes: 1210 (EIA Metric 3528-21), 2917 (EIA Metric 7343-31) and 2917 (EIA Metric 7343-20). The full voltage range for the series spans 4V to 50V, and capacitance values span 10µF to 220µF with a ±20% capacitance tolerance. They may be operated up to 90% of rated voltage.
