Hermetically sealed polymer chip capacitors
20 April 2016
Passive Components
AVX has extended its award-winning TCH series of high-voltage, hermetically sealed polymer chip capacitors with the addition of a new 33 μF/ 75 V 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, these capacitors are an effective polymer solution for mission-critical applications including automotive, avionics, aerospace, defence, 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 85°C and rated temperature, and exhibit low ESR, low derating capabilities, low leakage current (0,1 CV), high ripple current, high capacitance (22 μF to 330 μF), and high voltages (10 – 100 V).
Housed in large CTC-21D hermetically sealed cases especially designed to provide high capacitance and stable operation in harsh environments, these parts are available with gold-plated J-lead, tin/lead-plated J-lead, and gold-plated undertab terminations. The dimensions for the J-lead models are 11,5 x 12,5 x 6,15 mm, and the dimensions for those with undertab terminations are 11 x 12,5 x 5,95 mm.
Rated for use in temperatures spanning -55°C to +125°C, the 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: 330 μF/ 10 V, 220 μF/ 16 V, 150 μF/ 25 V, 100 μF/ 35 V, 47 μF/ 50 V, 33 μF/ 75 V and 22 μF/ 100 V; nearly 20 additional codes spanning 15 μF to 680 μF and 10 V to 100 V are actively in development.
