Capacitor Bungs

Different capacitor brands and sizes have differently shaped bungs (the rubber seal at the bottom of an aluminum electrolytic or aluminum polymer capacitor). The different shapes help with stress on the leads (not confirmed). Here are some different bungs from different manufacturers. Note that bungs might be different between series and production date.

2 Semicircle Bung

This bung is present on Elna and Partsnic capacitors.

Black=high parts of the bung. Black Circles=Holes in the bung for the capacitor leads.

Flat Bung

These capacitors have no shape to their bungs on some capacitors: Chang, Fujicon, Gather, Gemcon, G-K, Hengcon, HZC, ICCC, Jakec, Jamicon, JWCO, L.H. Nova, Marcon, OST, Samxon, Teapo, Telecon, TF, and United

I-Bung

I Bung

This bung is present on smaller United Chemi-Con capacitors as well as Partsnic, Rubycon, Samwha, Samyoung, Sang Jing, Shoei, and Taicon capacitor

Black=low parts of the bung. Holes=Holes in the bung for the capacitor leads.

T-Bung

T Bung

This bung is present on larger United Chemi-Con capacitors.
