513 Series Trimmer Capacitor
Outstanding Features
♦
Only .196”/4.98mm diameter x
.080”/2.03 mm high.
♦
Ideal for wide range of products
requiring real miniaturized capaci-
tance trimming.
♦
Operates efficiently at -55°C to
+85°C.
♦
Available in your choice of three
basic terminal arrangements.
♦
No metal or mechanical attach-
ments protruding beneath the base
plane.
♦
Monolithic Rotor design offers
optimum stability for higher ca-
pacitance ranges. Eliminates
need to use unstable higher K di-
electric materials. Monolithic con-
struction offers greater rugged-
ness which cannot be achieved
when using single plate construc-
tion, particularly with fragile Hi-K
Dielectric materials.
