GTO MKP Data Sheet

WIMA GTO MKP capacitors are especially designed to attenuate voltage spikes on GTO (Gate-Turn-Off) Thyristors and IGBT (Insulated Gate Bipolar Transistor). They are manufactured in dry-type technology with a dielectric of metallized polypropylene film and encapsulated in a cylindrical plastic case sealed with self-extinguishing polyurethane resin. Their construction creates outstanding features, e.g.:

Very low self-inductance
High pulse reliability
High rms current carrying capability
Excellent self-healing properties
High shock and vibration resistance
Outstanding mechanical stability
Almost unlimited life expectancy

Fields of applications are designs where high current and voltage carrying capabilities are required, e.g. converter equipment in power generation or in traction technology for train drives, hoists, crane drives etc.

WIMA GTO MKP capacitors are available with capacitances from 1.0 µF through 100 µF and with nominal voltages from 400 VDC through 1500 VDC. For mounting purposes M6 and M8 threaded terminations are possible. Customer-specific requirements can be realized on demand.
