Tantalum Lead Seals

Tantalum Capacitor Lead Seal is a unique two-sided fluoropolymer film engineered to assure a highly reliable seal against electrolyte diffusion along the tantalum anode wire in solid tantalum capacitors. The thin film thickness punches easily allowing capacitor manufacturers to form small diameter washers with a very low thickness profile. The lead seal washers position easily and resist distortion during the oxidation and impregnation process. Both DP25 and DP13 are packed in spools, typically on a 3 in core.

The lead seal is designed and manufactured by Electrolock.  Admat is the exclusive distributor for the international market.
