AVX Corporation has extended its award-winning TCH Series high voltage, hermetically sealed polymer chip capacitors with the addition of a new 33µF/75V code. Packaged in robust, hermetically sealed ceramic cases filled with inert gas in order to eliminate the potential for materials and performance degradation resulting from exposure to high temperature, high humidity, and ambient atmosphere, TCH Series polymer chip capacitors — which were recently recognized with Electronics Weekly’s 2015 Passive and Electromechanical Product of the Year Elektra Award — are the world’s first effective polymer solution for mission-critical applications, including: automotive, avionics, aerospace, defense, pulse power, and power supplies.
Manufactured and screened using AVX’s patented Q-Process, which identifies and removes components that may experience excessive parametric shifts or operational instability, TCH Series polymer chip capacitors exhibit high reliability endurance of up to 10,000 hours at 85ºC and rated temperature, and exhibit: low ESR, low derating capabilities, low leakage current (0.1CV), high ripple current, high capacitance (22µF to 330µF), and the highest voltages (10–100V) of any space-grade SMD polymer capacitor currently available on the market.
Housed in large CTC-21D hermetically sealed cases especially designed to provide high capacitance and stable operation in harsh environments, TCH Series high voltage polymer chip capacitors are available with gold-plated J-lead, tin/lead-plated J-lead, and gold-plated undertab terminations. The dimensions for TCH Series capacitors with J-leads are 11.5mm x 12.5mm x 6.15mm, and the dimensions for those with undertab terminations are 11mm x 12.5mm x 5.95mm. Rated for use in temperatures spanning -55ºC to +125ºC, TCH Series capacitors are RoHS compliant and lead-free compatible, and may be supplied in waffle or bulk packaging. As a result of the latest extension, the series is now available in seven codes: 330µF/10V, 220µF/16V, 150µF/25V, 100µF/35V, 47µF/50V, 33µF/75V, and 22µF/100V; however, nearly 20 additional codes spanning 15µF to 680µF and 10V to 100V are actively in development.
