Polymer chip caps for automotive

23 March 2016 Passive Components

AVX has introduced the robust new TCQ series of automotive conductive polymer chip capacitors.

Qualified to the AEC-Q200 specification for passive components, it meets the challenging 125°C lifetime stability test and humidity bias testing at 85°C and 85% relative humidity for up to 1000 hours.

The capacitors feature conductive polymer electrodes which enable a benign failure mode under recommended use conditions, and exhibit basic reliability of 1% per 1000 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 TCQ series is 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 4 V to 35 V, and capacitance values span 4,7 F to 220 F with a ±20% capacitance tolerance. The capacitors are also 3x reflow compatible at 260°C, and are rated for operating temperatures ranging from -55°C to +125°C.
