The 30 mOhm ESR keeps ripple heating under control — for a 1 A ripple current, dissipation is just 30 mW, well within the part's thermal budget even at 125°C ambient. The 2917 (7343 Metric) surface-mount package, size code D, sits on a standard 7.30 x 4.30 mm footprint. ## ESR and ripple current — what the 30 mOhm buys Equivalent series resistance of 30 mOhm is low for a 470 µF tantalum at 6.3 V. That ESR directly sets the ripple current rating and the output voltage ripple in a DC-DC converter. A 500 kHz buck switching 2 A sees roughly 15 mV of ripple across the capacitor alone — the ESR term dominates over the capacitive term at that frequency. The ±20% tolerance on the 470 µF nominal capacitance is standard for tantalum electrolytics. The actual capacitance varies with temperature and DC bias — at 125°C and rated voltage, expect the value to drift within the tolerance band. For a filter pole or timing circuit, account for the full spread at the temperature extremes.","metaTitle":"TPMD477M006R0030 KYOCERA AVX TPM Series 470 µF Molded","metaDescription":"Active KYOCERA AVX TPMD477M006R0030 molded tantalum capacitor: 470 µF, 6.3 V, 30 mOhm ESR, 2917 package, -55 to 125°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Specialty Capacitors"],"specifications":{"Mfr":"KYOCERA AVX","Type":"Molded","Series":"TPM","Package":"Tape & Reel (TR)","Features":"General Purpose","Tolerance":"±20%","Capacitance":"470 µF","Failure Rate":"-","Lead Spacing":"-","Mounting Type":"Surface Mount","Package / Case":"2917 (7343 Metric)","Product Status":"Active","Voltage - Rated":"6.3 V","lifecycle_stage":"unknown","Lifetime @ Temp.":"-","Size / Dimension":"0.287\\\" L x 0.169\\\" W (7.30mm x 4.30mm)","Height - Seated (Max)":"0.122\\\" (3.10mm)","Operating Temperature":"-55°C ~ 125°C","Manufacturer Size Code":"D","ESR (Equivalent Series Resistance)":"30mOhm"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.4554","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/3086f98da6213e3fbc87cd7ed7e9cc69.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Where can I buy TPMD477M006R0030?","answer":"TPMD477M006R0030 is available to order through our independent distribution channel.
