New T4Z Medical Series HRC4000 Tantalum Capacitors for Non-Critical Medical Devices

T4Z Series

Manufactured in compliance with strict FDA regulations, the T4Z Medical Series delivers consistent, high-reliability performance with the lowest DCL values in the market (0.01CV down to 0.005CV) & offers short, stable lead-times extending to a maximum of eight weeks, providing an ideal alternative to commercial capacitors

FOUNTAIN INN, S.C. (March 22, 2018) – AVX Corporation, a leading manufacturer and supplier of advanced electronic components and interconnect, sensor, control, and antenna solutions, has released the new T4Z Medical Series HRC4000 medical-grade tantalum capacitors. Designed to replace commercial capacitors in the filtering, hold-up, and charging circuits of non-critical medical devices that require high-reliability and strict change control, including: implantable, non-life-sustaining devices, such as heart monitors, neurostimulators, insulin pumps, and temporary cardiac monitors; external, life-sustaining devices, such as automated external defibrillators and external heart pump controllers; and external non-life-sustaining devices, including patient monitoring and diagnostic equipment, the new T4Z Medical Series solid tantalum capacitors are based on a MIL-PRF-55365 product line with more than 25 years of proven high-reliability performance in the medical industry. To ensure consistent, high-reliability performance, the series is manufactured at AVX’s high-reliability, ISO-13485-certified plant in Biddeford, Maine, using strict manufacturing control, statistical screening, and testing procedures compliant with FDA regulations for medical devices.

T4Z Medical Series capacitors offer the lowest DC leakage values in the market: 0.01CV standard, with custom potential down to 0.005CV — or half that of typical industry limits — enabling longer lifetime performance and improved reliability compared to commercial tantalum capacitors. They are currently available in eight compact, lightweight case sizes ranging from 2.54mm x 1.27 mm x 1.27mm (L x W x H) ±0.38mm and 0.016g to 7.24mm x 3.81mm x 2.79mm ±0.38mm and 0.335g with solder-plated, solder-fused, gold-plated, or 100% tin terminations. They offer capacitance values extending from 0.1μF to 330μF, eight standard voltage ratings spanning 4–50V, and rated operating temperatures extending from -55°C to +125°C. Custom DCL and ESR values are available upon request.

The T4Z Medical Series utilizes the industry-leading design for molded tantalum capacitors intended for use in high-reliability medical devices, which is conservative, robust, and strictly change-controlled to ensure continuity. They are manufactured using Weibull reliability grading, which subjects each batch to accelerated burn-in to provide a calculated failure rate; military-style screening and conformance testing, which ensures consistent, high-reliability part performance; and process control, which ensures a stable, normalized leakage distribution. In addition, each lot is subjected to sample function testing, which simulates the manufacturing environment to further ensure exceptional part performance. As a result, T4Z Medical Series capacitors deliver basic reliability better than 0.1% per 1,000 hours with a 90% confidence level.

“Subjecting our T4Z Medical Series HRC4000 medical-grade tantalum capacitors to such rigorous design and manufacturing process controls, statistical screening, and testing procedures allows us to consistently achieve higher-reliability components with significantly lower DC leakage levels than commercial solid tantalum capacitors, and to better satisfy the exacting demands of even non-critical medical applications,” said Lizzie Geismar, product marketing manager for AVX’s high-reliability tantalum division.

T4Z Medical Series capacitors can be shipped in bulk, 7” tape and reel, or waffle packaging, and — by virtue of being manufactured in a facility with five-plus years of guaranteed tantalum powder — are not subject to the long lead-times common to the commodity tantalum market, instead offering short, consistently stable lead-times that extend to a maximum of eight weeks.
