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.”

Notes
• Alternate lead spacings of 7.5 mm and 10 mm are available bulk or tape and reel on request.
• Minimum lead clearance according to IEC 60384-14: 0.118" (3 mm)
TAPE AND REEL OPTIONS
Part number codes and specifications for tape and reel packaging are found in the general information document - find web-link
below.
OPTIONAL 3-LEADED STYLE
An optional 3-leaded construction is available. It consists of a single capacitor with the two outside leads attached to one
electrode, and the center lead attached to the electrode. Used in feed-thru or line-to-ground applications, it allows a short
ground lead for enhanced high frequency performance.
