Vishay offers automotive-grade tantalum polymer chip capacitors

Vishay Intertechnology has launched a new series of automotive-grade vPolyTan surface mount polymer tantalum molded chip capacitors.

Designed to deliver better performance in high temperature and high humidity operating conditions, the AEC-Q200 qualified Vishay Polytech T51 series offers lower ESR, lower voltage derating and a benign failure mode. The series also maintains higher volumetric efficiency than traditional tantalum capacitors.

Furthermore, these technological advantages place this technology above multilayer ceramic chip capacitors (MLCC) and aluminum capacitors in a comparable capacitance range.

Offered in compact D (EIA 7343-31) and V (EIA 7343-20) sizes, the new devices offer a broad capacitance range from 6.8 to 330 µF, overvoltage ratings from 2.5 to 35 V, and a tolerance ±20% capacitance. Featuring a highly conductive polymer cathode system, the capacitors provide ultra-low ESR of 120 mW at 40 mΩ at +25°C.

Featuring a rugged design for harsh environments, the T51 Series devices offer high-temperature operation up to +125°C — with voltage derating above +105°C — and a high-temperature charge time of up to 2,000 hours.

Combined with 2.37A ripple current, the capacitors are ideal for decoupling, smoothing and filtering in switch mode and point-of-load (POL) power supplies for automotive ADAS, infotainment and other in-vehicle electronic systems. Featuring lead-free (Pb) terminations, the T51 series is RoHS compliant, halogen-free and Vishay Green.
