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
