The CSP 305A and CSP 305B conduction-cooled capacitors provide up to 300 kVAr of power.
These capacitors have similar electrical characteristic but differ in their physical dimensions and in the number of mounting holes.

Please note that the newer CSP 405A and CSP305A/600  have the same physical dimensions as the CSP 305A but are rated for higher voltage and higher current and can carry up to 400 and 600kVAr respectively.

Standard applications: Induction heating, heat treatment, plasma applications, resonant circuits, medical imaging, wireless power transfer, EV (electric vehicle) charging, IPT, high frequency inverters,etc.


  • Polypropylene Conduction-cooled capacitor
  • High Power Self-Healing capacitor
  • Low ESR
  • Low losses
  • UL94-V0 available upon request.


The CSP 305A capacitor complies with RoHS.
