AVX Corporation has introduced the robust new TCQ Series automotive conductive polymer chip capacitors. Qualified to the Automotive Electronics Council’s AEC-Q200 specification for passive components, the TCQ Series meets the AEC’s challenging 125°C lifetime stability test and humidity bias testing at 85°C and 85% relative humidity for up to 1,000 hours.
TCQ Series automotive conductive polymer chip capacitors feature conductive polymer electrodes, which enable a benign failure mode under recommended use conditions, and exhibit basic reliability of 1% per 1,000 hours at 85°C and rated voltage with 60% confidence. The series also delivers low DC leakage (0.1CV), high capacitance, and stable electrical performance at operating temperatures as high as 125°C in small, low profile case sizes, which makes them ideal solutions for a wide variety of space-constrained, harsh environment automotive, industrial, telecommunications, and DC/DC converter applications.
Lead-free compatible and RoHS compliant, the new TCQ Series automotive conductive polymer chip capacitors 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 35V, and capacitance values span 4.7μF to 220μF with a ±20% capacitance tolerance. TCQ Series capacitors are also 3x reflow compatible at 260°C, and are rated for operating temperatures ranging from -55°C to +125°C,. Manufactured at an ISO/TS 16949 certified plant in accordance with the Automotive Electronics Council’s AEC-Q200 specification for passive components, TCQ Series capacitors are supplied with 100% tin terminations on 7” or 13” reels, and lead time for the series is 10–12 weeks.
