The -55°C to 125°C operating range covers military and industrial temperature grades, so it survives cold starts and thermal cycling without the capacitance drop you see in ceramics at DC bias. The 45 mOhm ESR is specified at 100 kHz — the frequency where switching regulators generate most of their ripple. At lower frequencies the ESR rises, so for 50/60 Hz bulk filtering you'd need a different part; this one is tuned for DC-DC converter output stages. ## Active lifecycle — no rush on the BOM line The Tape & Reel packaging (Cut Tape also available) means it ships in reel quantities for automated pick-and-place. No special handling beyond standard MSL precautions for molded tantalum caps.","metaTitle":"KYOCERA AVX TPSE477K010R0045V Molded Tantalum, 470 µF, 10 V","metaDescription":"KYOCERA AVX TPSE477K010R0045V molded tantalum capacitor, 470 µF ±10%, 10 V, 45 mOhm ESR, 2917 package.
