KEMET T540B336M006AH8610WAFL

KEMET Organic Capacitors (KO-CAP) are solid electrolytic capacitors that use a conductive polymer cathode, enabling extremely low ESR at high frequencies and improved capacitance retention. KO-CAP combines the low ESR of multilayer ceramics, the high capacitance of aluminum electrolytic capacitors, and the volumetric efficiency of tantalum capacitors — all in a single SMT package. Unlike liquid electrolyte-based capacitors, KO-CAP offers exceptionally long service life and high ripple current capability.

HRA polymer electrolytic capacitors deliver the same performance advantages as other KO-CAP series while providing screening options relevant to Hi-Rel applications.

These HRA-grade components offer multiple surge current screening options. A derating of 10–20% is recommended for these capacitors, making them suitable for operating voltages from 0.8 to 48 or 50 VDC.

These are the first polymer electrolytic capacitors for which failure rates can be selected based on KEMET's KO-CAP reliability assessment methodology. This methodology uses accelerated conditions (voltage and temperature) applied to on-board samples to evaluate long-term device reliability. Available failure rates are B (0.1% per 1,000 hours), C (0.01% per 1,000 hours), and D (0.001% per 1,000 hours).
