The KYOCERA AVX SCMT22C505PRBA0 is a 5 F supercapacitor from the SCM series, rated at 5 V with a maximum ESR of 100 mOhm at 1 kHz.
What the ESR and capacitance mean for your circuit
The 100 mOhm ESR at 1 kHz sets the self-heating floor during ripple current — at 5 F and 5 V, the time constant is 0.5 seconds, so this cap suits hold-up and pulse-power applications where the load draws short bursts rather than continuous AC ripple. The 0%, +100% tolerance on the 5 F capacitance means the actual value can range from 5 F to 10 F — a design that relies on a tight capacitance window for timing or filtering needs to account for this spread at the BOM level.
