Compact film capacitors offer high pulse strength and current capability

TDK-Epcos has launched two new series of MMKP capacitors which employ metallized film on both sides. The new capacitors offer particularly high pulse strength as well as a high current capability. Depending on the type and frequency, the permissible current can be up to more than 10Arms. A further outstanding feature is the compact design of the MMKP series. The capacitors have dimensions of between 4mm x 9mm x 13mm and 11mm x 18.5mm x 18mm and are available with lead spacings of 10mm and 15mm. The B32641B and B32642B series of rugged MMKP capacitors are designed for voltages of 630VDC or 1000VDC and cover a capacitance range from 4.7nF to 150nF. The maximum operating temperature is +110C. The main applications are circuits that operate with high frequencies and currents, including resonant circuits of power supplies with an LLC topology. The MMKP capacitors are also suitable for use in switch-mode power supplies or ballasts for lighting systems.
