Offered in three molded case sizes, the TF3 series capacitor is designed to provide a very high level of protection against short circuits in safety-critical applications. TF3 series devices feature an internal electronic fusing mechanism that activates within 0.1 second with a minimum of 5 A applied at +25 °C. In the event of a failure due to excessive current flow, this fusing prevents damage to circuit components. With their low ESR down to 0.25 Ω at +25 °C and 100 kHz, the capacitors are optimized for high-current applications (> 10 A) requiring this level of safety. The TF3 devices offer a capacitance range of 0.47 μF to 470 μF in the C, D, and E case codes. The capacitors provide a high ripple current carrying capability and feature a voltage range from 4 V to 50 V over an operating temperature range of -55 °C to +125 °C.

Compatible with high-volume automatic pick-and-place equipment, the TF3 series features standard RoHS-compliant tin terminations, with Sn/Pb terminations available. The devices are 100% surge current tested and meet EIA 535BAAC requirements
