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.
