Featuring a robust anode design, the TM3 series is 100% surge current tested (B, C, D, and E case sizes) and available with Weibull grading and Hi-Rel screening options. The Vishay Sprague TM3 devices are optimised for input capacitor filters on DC / DC converters, hot plugging surges on battery chargers, low-drop-out devices, and capacitor charge pumps. Typical end products will include glucose meters, infusion pumps, nebulisers, and thermometers. Vishay manufactures the TM3 series at its Dimona, Israel manufacturing facility. In addition to being ISO9001-certified, the Dimona plant was recently certified to ISO13485 standards, which outline medical device regulatory requirements for quality management systems and facilitate the requirements needed for medical device regulatory compliance by the U.S. FDA.

TM3 devices are offered in a moulded package in five standard EIA-535BAAC case codes: A, B, C, D, and E. The capacitors provide a capacitance range from 1 µF to 220 µF over voltage ratings from 4V to 20V; capacitance tolerances of ± 10% and ± 20%; high ripple current carrying capability to 11A; and an operating temperature range of -55°C to +125°C with voltage derating.
