This release in:

MALVERN, PENNSYLVANIA — Sept. 30, 2010 —Vishay Intertechnology, Inc. (NYSE: VSH) today introduced the new TM8 series of high-reliability, surface-mount tantalum capacitors with very low DC leakage current (DCL) down to 200 nA.

DC leakage levels in early medical device platforms were at tolerable levels; however, lower levels are now required. By utilizing Vishay’s proprietary multi-array packaging (MAP), the new TM8 devices realize significant reduction in DC leakage and better stability. Leveraging the patented MAP assembly technology, the TM8 capacitors offer a robust design for the highest possible reliability and efficiency in these applications. In addition, the devices go through rigorous processing and testing patterned after MIL-PRF-55365.

The TM8 series offers a wide range of capacitance−voltage (CV) ratings from 1 µF / 40 V to 47 µF / 10 V in seven compact case sizes. The capacitors are well suited for long-term performance in critical applications including implantable medical devices, medical instrumentation, and military/aerospace systems. Special screening and custom application-specific options are also available for the TM8 devices.

The devices released today are optimized for filtering, coupling/decoupling, DC blocking, and energy storage applications in medical devices such as pacemakers, ICD, neurological stimulators, hearing aids, and cochlear implants; medical instrumentation including patient monitoring equipment, automated drug administration systems, and imaging and diagnostic equipment; and military and aerospace hybrid microcircuits/multichip modules, smart munitions, GPS systems, sensors, and handheld portable electronic systems.

To ensure reliable, long-term performance in demanding environments, reliability level screening options include a 40-hour burn in period at + 85 °C or Weibull grading level B, which screens for a 0.1 % failure rate. Surge current options include option A (10 cycles at + 25 °C) and option B (10 cycles at − 55 °C / + 85 °C). Vishay offers a dedicated production facility with highly skilled staff to ensure quality in all phases of production.

The capacitors’ compact L, M, N, P, R, T, and W case codes are ideal for space-constrained portable/implantable applications, while their low DCL ensures efficient operation and extended battery life. The TM8’s L-shaped terminations allow for superior board mounting and visual inspection (or automated optical inspection) of the solder fillet in the end user’s production.

The RoHS-compliant devices feature an operating temperature of - 55 °C to + 85 °C, + 125 °C with voltage derating, over a voltage range of 2 WVDC to 40 WVDC.

Offered in tape-and-reel packaging per EIA-481-1, samples and production quantities of the TM8 capacitors are available now, with lead times of 10 weeks for larger orders.
