The TPSE686M020R0125: The 125 mOhm ESR limits self-heating under ripple current — for a typical 12 V input rail, the derating margin to 80 % of rated voltage (16 V) keeps the part inside its safe operating area. Surface-mount assembly with reflow profile per J-STD-020 is expected.
The molded case provides mechanical protection and is compatible with standard cleaning solvents.
The ESR is 125 mOhm. This value governs the capacitor's ripple current capability and self-heating — a lower ESR reduces power dissipation under AC load, which is critical for decoupling on switching regulator outputs.
