e51 capacitor

The capacitors of the E51 series are primarily suitable for use in low inductance buffer circuits with higher voltages as well as in discharge circuits, and they are suitable for use in power electronics in general.

Despite the high voltage rating, they are manufactured in dry technology and without expensive bushings. Inside the can, made of self-extinguishing plastic, the capacitor element is enclosed in solid resin (PUR). Connection is made through robust terminals with internal thread. Along with their very good ratio of capacitance to volume, these capacitors also have high pulse strength and very good self-healing characteristics without loss of capacitance.

Function: snubbing, commutation, smoothing, filtering, discharge

Application:

  • traction and drives
  • frequency controlled drives
  • “green” energy generation (inverters for solar/wind power)
  • HVDC transmission
  • high voltage generation
  • LV/MV inverters/rectifiers/rotary transformers
  • resonating circuits
  • HF filters
  • surge suppression (as separate range “E93 DSC”)
  • transient protection of transformers and MV motors
