Solid tantalum chip capacitors for medical devices

The new TM3 series capacitors are manufactured at Vishay’s manufacturing facility in Dimona, Israel. The Dimona plant is ISO9001-certified and was also recently certified to ISO13485 standards. The ISO13485 standards outline medical device regulatory requirements for quality management systems and facilitate the requirements needed for medical device regulatory compliance by the U.S. Food and Drug Administration.

The Vishay TM3 capacitors unveiled today are optimized 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, nebulizers, and thermometers, as well as other non-life-support medical monitoring and diagnostic instruments for in-home and hospital.

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

Available with 100 % matte tin or tin/lead terminations, the TM3 series is RoHS-compliant and halogen-free. The devices are compatible with high-volume automatic pick-and-place equipment, and their dry packaging is compliant to the JEDEC-033 standard.

Samples and production quantities of the new TM3 series are available now, with lead times of 12 weeks for larger orders.
