The TPSE477M006R0045: That ESR figure is the key selection parameter: at 45 mOhm, the capacitor can handle ripple currents typical of a switching regulator output without self-heating that would shorten life or shift capacitance. It belongs to the TPS series, KYOCERA AVX's general-purpose molded tantalum line, in the standard 2917 (7343 metric) case with manufacturer size code E. The ±20 % tolerance is the norm for tantalum electrolytics — the capacitance at the rated voltage will sit within that band across the operating temperature range.
Active lifecycle — no design-in restrictions
The molded case construction provides mechanical stability across this range.
Footprint and board integration
This is a standard tantalum footprint shared across multiple manufacturers — the pad layout is interchangeable with other E-case-code tantalum capacitors, simplifying second-sourcing on the same PCB. Surface-mount assembly with Tape & Reel or Cut Tape packaging options. The molded body is compatible with reflow soldering profiles typical for lead-free assemblies.
