Surface-mount molded tantalum chip capacitors offer low DC leakage current in five standard case sizes

March 15, 2012 // By Paul Buckley
Vishay Intertechnology, Inc. has introduced the new TL3 series of TANTAMOUNT surface-mount tantalum molded chip capacitors, the industry’s first such devices to offer DC leakage current (DCL) as low as 0.005 CV, a capability that enables system designers to extend battery run-time in portable devices.

Offered with a wide range of capacitance and voltage values, devices in the TL3 series are optimized for a wide variety of demanding applications that require long product life, such as battery-operated equipment, portable instrumentation, tire-pressure monitoring, medical instruments, local power supplies, hand-held Instruments, and battery backup supplies.

The TL3 capacitors are offered in a molded package in five standard EIA-535BAAC case codes — A, B, C, D, and E — with standard and low ESR options. The devices offer a capacitance range from 0.1 µF to 470 µF over voltage ratings from 4 VDC to 63 VDC, with capacitance tolerances of ± 10 % and ± 20 %. Case codes B, C, D, and E are 100 % surge current tested and offering improved reliability of 0.5% / 1,000 hours. The devices are available with RoHS-compliant tin terminations and halogen-free.

Samples and production quantities of the new TL3 series are available now, with lead times of eight weeks for larger orders.
