APPLICATIONS

• X1 / Y2 according to IEC 60384-14

• Line-to-line filtering (Class X)

• Line-to-ground filtering (Class Y)

• Primary and secondary coupling (SMPS)

• EMI / RFI suppression and filtering

DESIGN

The capacitors consist of a ceramic disc of which both sides

are silver-plated. Connection leads are made of tinned

copper having a diameter of 0.032" (0.81 mm) or 0.025"

(0.64 mm). The capacitors may be supplied with radial

kinked or straight leads having a lead spacing of 0.375"

(9.5 mm) or 0.250" (6.4 mm). The standard tolerance is

± 20 %. Coating is made of flame retardant epoxy resin in

accordance with “UL 94 V-0.”
