Safety Recognized/High Voltage Ceramic Capacitors

Type KY (Basic Insulation) -IEC60384-14 Class X1, Y2-

s Features

1. We design capacitors in much more compact size than

type KH, having reduced the diameter by 25% max.

2. Operating temperature range guaranteed up to 125

degrees (UL: 85 deg.).

3. Dielectric strength:

AC2000V (In case of lead spacing F=5mm)

AC2600V (In case of lead spacing F=7.5mm)

4. Class X1/Y2 capacitors which are recognized by

UL/CSA/BSI/SEMKO/SEV/VDE/FIMKO/NEMKO/DEMKO/

NSW.

5. Coated with flame-retardant epoxy resin (conforming

to UL94V-0 standard).

6. Cost-saving automatic insertion available.

7. Available product for RoHS Restriction

(EU Directive 2002/95/EC).

s Applications

1. Ideal for use as X/Y capacitors for AC line filter

and primary-secondary coupling on switching power

supplies and AC adapters.

2. Ideal for use on D-A isolation and noise absorption

for DAA modems without transformers.
