New surface mount capacitors from Vishay features DC leakage current down to 200 nA

Vishay has released the new TM8 series of surface-mount tantalum capacitors with DC leakage current (DCL) down to 200 nA. This device leverages Vishay's MAP assembly technology. The TM8 capacitors go through the processing and testing patterned after MIL-PRF-55365. The TM8 series offers capacitance?voltage (CV) ratings from 1 µF / 40 V to 47 µF / 10 V in seven compact case sizes.

These TM8 capacitors are suitable for applications such as implantable medical devices, medical instrumentation, and military/aerospace systems. These devices 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. Special screening and custom application-specific options are also available for the TM8 devices.

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 suggested for space-constrained portable/implantable applications. The TM8's L-shaped terminations allow for board mounting and visual inspection (or automated optical inspection) of the solder fillet in the end user's production.

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