Pin/Solder Tag/Audio Aluminum Electrolytic Capacitors
ALP20 and ALT20/21 Series, +85°C
Overview
KEMET's ALP20 and ALT20/21 Series of capacitors features low ESR, high ripple current ratings and outstandingly good high frequency impedance.
Applications
It should be pointed out that the ALP solder pin and ALT solder tag range details are incorporated herein, primarily, for maintenance/replacement purposes.
Benefits
• Solder tag (ALT) and DIN standard solder pin (ALP) • Long life, up to 26,000 hours at +85°C • ALC snap-in should be considered for new designs

Shelf Life
The capacitance, ESR and impedance of a capacitor will not change significantly after extended storage periods, however the leakage current will very slowly increase. KEMET products are particularly stable and allow a shelf life in excess of three years at 40°C. See sectional specification under each product series for specific data.
Re-age (Reforming) Procedure
Apply the rated voltage to the capacitor at room temperature for a period of one hour, or until the leakage current has fallen to a steady value below the specified limit. During .
