General Purpose Metallized Polyester Film Capacitors
R66, Radial, 7.5 mm Lead Spacing, 50 – 630 VDC
(Automotive Grade)
Overview
The R66 is constructed of metallized polyester film (wound
or stacked technology) with radial leads of tinned wire.
Radial leads are electrically welded to the contact metal
layer on the ends of the capacitor winding. The capacitor is
encapsulated with thermosetting resin in a box of material
meeting the UL 94 V–0 requirements.
Automotive grade devices meet the demanding Automotive
Electronics Council's AEC–Q200 qualification requirements.
Applications
Typical applications include blocking, coupling, decoupling,
bypassing, and interference suppression in low voltage
applications such as automotive. Not suitable for across-
the-line application (see Suppressor Capacitors).
