The MKP4D042206B00KSSD is a part of the WIMA MKP4 series of polypropylene film paper capacitors. They are designed for use in pulse circuits, power supply circuits, audio crossover networks, and any other circuit that requires broad frequency response. They have a rated voltage of 250 VDC and a capacitance of 2.2 µF. They have a KSSD dielectric and an X7R temperature stability. The capacitors are rectangular in shape with a single lead terminal on each side, and the case is made from flame-retardant plastic.
