Medical grade tantalums for implantable devices

August 29, 2013 // By Graham Prophet
AVX' TAZ HRC5000 medical grade tantalum series claims leading DC leakage standards in some of the smallest tantalum chip capacitor cases currently available.

Designed for use in implantable medical devices, the high-reliability, medical-grade tantalum capacitor series is rated for 4V to 50V and -55ºC to +125ºC, has a capacitance range of 0.1 µF to 330 µF, and features extremely low DC leakage limits well below typical industry values. Available in case sizes ranging from A-H, the capacitors are also some of the smallest tantalum chip capacitors currently on the market.

The TAZ HRC5000 series is available with several customisation options to suit individual medical and other high-reliability/low-leakage tantalum applications. These include custom DC leakage limits, various plating materials (tin/lead solder, 100% tin, or gold), and standard and low ESR variations, in addition to two reliability verification procedures: Weibull grading and surge current testing according to MIL-PRF-55365. TAZ HRC5000 medical grade tantalum series parts are manufactured and tested at AVX’s ISO 13485-certified, high-reliability tantalum manufacturing facility in Biddeford, Maine.
