Type 168/185 Metallized Polyester Radial Lead Capacitors
Radial Box Metallized Polyester Capacitors for Automatic Insertion
The Type 168/185 series radial lead metallized polyester
box capacitors are available in bulk (Type 168) or on ammo
pack or radial tape and reel (Type 185). These capacitors
are constructed in rugged rectangular plastic cases and all
come with 5.0 mm (0.197”) lead spacing. They are good
for general purpose applications such as bypass, decoupling,
energy storage/discharge and arc suppression.
Highlights

♦ Case and epoxy fill meets UL94V-0
♦ 5.0 mm (0.197”) lead spacing
♦ Bulk, tape and reel or ammo pack
♦ Non-inductively wound
♦ Non-polar
♦ Low leakage

If the working voltage (V) is less than the nominal voltage (Vn),
the capacitor can work at higher dv/dt. In this case, the maxi-
mum value allowed is obtained by multiplying the above value
with the ratio Vn/V.
