Product Overview and Selection Scope
NM5R5L104D-P100512 is a 5.5 V combined supercapacitor with a 0.1 F nominal capacitance and radial leads. It is intended for low-power energy storage where a short hold-up interval, state retention or controlled backup discharge is required.
A supercapacitor is not a regulated power source. Validate voltage decay, ESR drop, charging current, reverse polarity risk, temperature, leakage and the minimum load operating voltage in the final circuit.

Capacitance and ESR Test Methods
Capacitance is determined from a controlled discharge interval after charging to rated voltage. ESR is measured with the specified 1 kHz AC method.
Leakage, Current and Energy Calculations
Before leakage-current measurement, discharge the capacitor for 1 to 24 hours. Apply rated voltage with constant voltage for 72 hours, then measure leakage current.
PCB Mounting, Soldering and Handling
Assembly conditions directly affect life and reliability. The following points summarize the handling cautions in the supplied specification.
Verify hole size, lead pitch, creepage, polarity marking, cleaning chemistry, solder profile and mechanical support with the assembler before release.
