Keywords:Vishay Intertechnology? tantalum? chip capacitors? medical monitoring?

Vishay Intertechnology recently unveiled its latest series of TANTAMOUNT surface-mount solid tantalum moulded chip capacitors boasting improved performance and reliability in a wide range of non-life support medical monitoring and diagnostic instruments for in-home and hospital use. The TM3 series is 100 per cent surge current tested (B, C, D, and E case sizes) and available with Weibull grading and Hi-Rel screening options.

Vishay manufactures the new 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. Food and Drug Administration.

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, nebulizers, and thermometers.

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 to 220?F over voltage ratings from 4V to 20V; capacitance tolerances of 10 per cent and 20 per cent; high ripple current carrying capability to 11A; and an operating temperature range of -55C to 125C with voltage derating.

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