Automotive-grade solid tantalum chip capacitors

Paul Boughton

Vishay Intertechnology's new series of moulded, automotive-grade MicroTan solid tantalum chip capacitors are designed for space-constrained automotive electronics.

The TP8 is the first AEC-Q200-qualified tantalum capacitor series to employ a high-volumetrically efficient packaging solution to enable industry-high capacitance-voltage ratings in small case sizes down to 0603.

Previously, the industry's offering of automotive-grade moulded chip capacitors was limited to A through D case sizes. With the TP8 series, designers now have access to a variety of smaller case sizes — including the 0603, 0805, and 0906 — with the same capacitance and voltage ratings found in the larger devices.

The TP8 series features capacitance-voltage ratings from 1.0 µF-40V to 100 µF-6.3V. Included in this range are industry-best values such as 1.0 µF-20 V in the 0603 case size and 100 µF-6.3V in the 1206 case. The devices offer standard capacitance tolerances of ±10% and ±20% and an operating temperature range of -55°C to 85°C, or 125°C with voltage derating.

With their small case sizes, the TP8 devices save board space for bulk capacitance, energy storage, filtering, and decoupling in space-constrained automotive applications including tire pressure monitoring systems, camera modules, rear view mirrors, and remote keyless entry.

The devices' rectangular molded case encapsulation is ideal for high-volume PCB assembly, and their lead (Pb)-free, L-shaped facedown terminations offer better mechanical and electrical contact to the solder pad than traditional facedown-style terminations. The RoHS-compliant capacitors are available in 8 mm tape and reel packaging per EIA-481.
