Heavy duty capacitors from Vishay with capacitance values up to 2235 µF

Vishay is extending its heavy-duty ESTA HDMKP capacitors for power electronic applications with new capacitance and packaging options.

The features of HDMKP capacitors are:
1) They are available in six standard voltages from 900 V to 2700 V (dc).
2) Previously offering capacitance values from 40 µF to 1100 µF, these capacitors now offer capacitance of up to 2235 µF, with a capacitance tolerance of ±5%.
3) They are aimed at dc and ac filtering and dc linking applications in power converters for UPS, wind turbines, and in power converters for traction and industrial drives and also serve as impulse discharge capacitors for magnetizing and welding.
4) These capacitors feature current ratings of 150 A.
5) It has an impulse current of up to 25 kA and self-inductance of less than 70 nH.
6) They offer 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.
7) This series offers four new case options. 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.
8) These capacitors meet IEC 61071-1, EN 61071, IEC 68-2, and IEC 61881 standards and terminal-to-terminal test voltage is 1.5 times the rated dc voltage for 10 seconds.

Operating temperature range: -40°C to +70°C at full rated voltage, or up to +100°C at half of the rated voltage.
