AVX Corp.’s new hermetically sealed tantalum polymer chip capacitors feature low equivalent series resistance (ESR), low derating capabilities, high ripple current, 1.5- to 680-µF capacitance, and 10- to 100-V voltage. Combining those specs with the use of conductive polymer electrodes and hermetic sealing, the TCH series capacitors offer the performance stability required for aerospace and other high-reliability applications. They also enable a significant payload reduction for power supplies, according to the company. The hermetically sealed CTC-21D ceramic cases are filled with inert gasses to eliminate material and performance degradation caused by exposure to high temperature, high humidity, and ambient atmosphere. Operating temperature ranges from −55° to +125°C. The capacitors weigh 2.4 g, and come with either J-lead or standard under-tab terminations.
