Tantalum Polymer Electrolytic Capacitors
Overview
The T550 axial and T555 surface mount polymer hermetic seal
(PHS) tantalum capacitor series are devices designed for
extreme conditions that must also retain optimal electrical
performance such as low ESR, frequency performance, and
capacitance retention. PHS capacitors are also manufactured
using KEMET’s F-Tech process which eliminates defects in
the dielectric that would otherwise be undetected and cause
potential failure during the operational life.
