Vishay Tantalum Chip Capacitors Feature High CV Ratings, Small Case Sizes
January 9, 2014 by John Day
Vishay Intertechnology, Inc. introduced a new series of molded, automotive-grade MicroTan® solid tantalum chip capacitors well-suited for space-constrained automotive electronics applications.
According to the company, 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 molded 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-40 V to 100 µF-6.3 V. Included in this range are industry-best values such as 1.0 µF-20 V in the 0603 case size and 100 µF-6.3 V 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, rearview 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.
Samples and production quantities of the TP8 capacitors are available now, with lead times of 10 weeks for larger orders. Pricing for U.S. delivery starts at $0.08 per piece. A datasheet is available at http://www.vishay.com/doc?40151 (TP8)
