Type 3186 85 C Aluminum Electrolytic, Screw Terminal
Best Value 85 C High Capacitance Screw Terminal Type
While Type 3186s 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
industrys highest vibration and shock withstanding and excellent
heat transfer. Besides increasing ripple current handling, the rilled
construction extends the great value of the Type 3186 into military
and transportation applications that require rugged mechanical
capability.
Highlights
- Rilled cans withstand high shock and vibration
- High ripple current capability
- High capacitance per can
