Capacitors save board space for automotive applications

Designed for next generation space-constrained automotive electronics, the TP8 series has been introduced by Vishay. AEC-Q200-qualified MicroTan solid tantalum chip capacitors, the series is suitable for bulk capacitance, energy storage, filtering, and decoupling in space-constrained automotive applications including tire pressure monitoring systems, camera modules, rearview mirrors, and remote keyless entry.

Until now, automotive-grade molded chip capacitors have been limited to case sizes A through D. Now, however, the TP8 series is giving designers access to the smaller case sizes (including the 0603, 0805, and 0906) with the same capacitance and voltage ratings as the larger devices. Vishay has stated that 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.

Operating over a temperature range of -55 to +85°C (or +125°C with voltage derating), the solid tantalum chip capacitors provide capacitance-voltage ratings from 1.0µF-40V to 100µF-6.3V and standard capacitance tolerances of ±10% and ±20%. The TP8 series offers industry best values including 1.0µF-20V in the 0603 case size and 100µF-6.3V in the 1206 case size.

The RoHS-compliant capacitors feature a rectangular molded case encapsulation suiting high-volume PCB assembly and are supplied in 8 mm tape and reel packaging per EIA-481. With lead-free, L-shaped facedown terminations, the capacitors provide better mechanical and electrical contact to the solder pad than traditional facedown-style terminations.

With lead times of 10 weeks for larger orders, the TP8 automotive-grade solid tantalum chip capacitors are available now for sampling and in production quantities.
