Selection anchor — ESR and lifetime on a 6.3 V rail
The TPSC107K006S0075: Rated 100 µF at 6.3 V with a 75 mOhm ESR measured at 100 kHz — this ESR value sets the self-heating under ripple current and directly limits the ripple current the capacitor can handle before the internal temperature rise cuts into the 2000-hour lifetime at 125 °C. The molded case (Type Molded) in a 2312 (6032 Metric) footprint, Size Code C, means it fits the standard C-case land pattern — no footprint adjustment needed when swapping between TPS series C-case parts.
Temperature grade and deployment scope
Rated -55 to 125 °C operating range with a 2000-hour lifetime at the 125 °C upper limit — this is the full military temperature band, so the part suits avionics power supplies, downhole instrumentation, and satellite bus decoupling where the ambient hits 125 °C and the board sees no forced air.
