Capacitance, voltage, and package fit
The TPSR105K025R2500: The 2.5 Ohm ESR at 25 V is the key loss parameter — it governs ripple current handling and self-heating in decoupling or filtering roles. For a typical board-level bypass application, the ESR sets the capacitor's impedance floor above self-resonance.
Lifecycle and supply posture
The TPS series from KYOCERA AVX is a standard molded tantalum line with broad distribution coverage.
