The capacitance-voltage point lands it in bulk decoupling or moderate-energy storage roles — think downstream of a 48 V bus or as a hold-up cap on a 24 V rail where the transient headroom needs margin. The 50 V rating gives comfortable derating on a 24 V supply (typically 80% of rated voltage for tantalum reliability). ## 300 mOhm ESR — the ripple-current constraint The 300 mOhm equivalent series resistance sets the self-heating limit under AC ripple. In a switching regulator output filter, the RMS ripple current through this cap generates I²R losses — at 1 A ripple, that is 300 mW dissipated inside the molded case. ## Size code D, 2917 footprint — board-fit realities The land pattern is common across the TPS series, so a PCB already laid out for a D-case tantalum accepts this part without a footprint change. The 3.1 mm height is the constraint in low-profile assemblies — it will not fit under a 3 mm board-to-board gap. ## Molded case and surface-mount handling The molded construction means the capacitor body is encapsulated in a solid epoxy case — no conformal-coat compatibility issues, but also no visual inspection of the internal anode connection. The ±10% tolerance is the standard bin for this series — no tight-sort options on this order code.","metaTitle":"KYOCERA AVX TPSD475K050R0300 TPS Series, 4.7 µF, 50 V","metaDescription":"KYOCERA AVX TPSD475K050R0300 molded tantalum capacitor, 4.7 µF, 50 V, ±10%, 300 mOhm ESR, -55 to 125°C.
