The ±20% tolerance is standard for tantalum electrolytics — the actual capacitance at 4 V bias will sit near the nominal 470 µF; derating to 50% of rated voltage (2 V) is common practice to improve reliability in low-impedance circuits. Sourced to order through independent distribution channels. No minimum order quantity restrictions beyond standard reel packaging.","metaTitle":"KYOCERA AVX TPSE477M004R0045 TPS 470µF 4V 45mOhm ESR","metaDescription":"KYOCERA AVX TPSE477M004R0045 TPS series molded tantalum capacitor, 470 µF, 4 V, 45 mOhm ESR, 2917 case.
