MDST SERIES
Miniature for Active-filter


Resin Coated Metallized Polyester Film Capacitor


  • MDST series is 450VDC and suitable for the circuit of Active-filter as noise suppression.
  • This series is smaller than MDS series in size, which is advantageous to save the space of PC board due to a thinner dielectric; 80% rate of MDS series
  • The permissible current is of the same as MDS series
  • Flame retardant epoxy resin (UL94V-0) coating type
