The TCX series is specifically designed with a proprietary material for discharge applications such as strobe circuit applications. The unique properties of the X7E material and the design of the TCX series makes them suitable for any discharge application which requires the capacitor to have a good damping characteristic. This series is also suitable for applications requiring a minimum change in capacitance over temperature (T/C). The TCX series is offered in sizes 0805, 1206 and 1210 and at 350Vdc and 630Vdc.
