Type 3188 85 °C Best Value, Screw Terminal, Aluminum

85 °C Long Life Screw Terminal Type

Type 3188 has twice the life of the 3186 and twice the

ripple-current capability. While the standard encasement

is by compression with the capacitor element captured

on an aluminum peg in the can bottom and a phenolic

peg in the top, rilled construction is available. With rilled

construction the element is secured by rills, spoon shaped

dimples in the side of the can. Rilled construction offers the

industry’s highest vibration and shock withstanding and

excellent heat transfer. Besides increasing ripple-current

handling, the rilled construction facilitates use in military

and transportation applications.

Highlights

- Rilled cans withstand high shock and vibration.

- 2 times the ripple-current capability

- High capacitance per can
