Vishay Extends 900-V to 2700-V Heavy Duty Capacitors for Power Electronics With New Capacitance Values Up to 2235 µF

The HDMKP capacitors are aimed at dc and ac filtering and dc linking applications in power converters for uninterruptible power supplies, wind turbines, and in power converters for traction and industrial drives. They will also serve as impulse discharge capacitors for magnetizing and welding.

The metallized-film HDMKP capacitors feature current ratings as high as 150 A, high impulse current of up to 25 kA, and low self-inductance of less than 70 nH.

In addition to their exceptionally low inductance and high current ratings, the HDMKP capacitors offer extremely low losses at high frequencies, low ESR, and high resistance to the effects of shock and vibration for high reliability and life expectancy in rugged environments.

In addition to new capacitance ratings, the series is gaining a new case option for a total of four. Capacitor height options range from 105 mm to 260 mm, with diameters of 84.4 mm and 116 mm. The devices feature a non-polar dielectric and are easily mounted using an integrated M 12 stud on their base.

Devices in the HDMKP series are specified for an operating temperature of -40°C to +70°C at full rated voltage, or up to +100°C at half of the rated voltage, and meet IEC 61071 1, EN 61071, IEC 68 2, and IEC 61881 standards. Terminal-to-terminal test voltage is 1.5 times the rated dc voltage for 10 seconds.
