The Type 943 polypropylene axial film capacitor is designed for high pulse and snubber applications, featuring very high dV/dt, low inductance, and self-healing properties. The part number 943C12P33K-F specifies a 0.33 µF capacitance with ±10% tolerance, rated for 1200 Vdc (430 Vac), measuring 20.2 mm in thickness, 29.6 mm in width, and 46.0 mm in length, with 1.0 mm terminal diameter. It operates from -55 ºC to 105 ºC with derated voltage above 85 ºC. The capacitor has a typical ESR of 6 mΩ at 100 kHz, an ESL of 28 nH, and supports a peak current of 528 A. The case is wrapped in UL510 polyester tape and filled with UL94V-0 epoxy. Termination is tin-plated copper wire.
