The ±10% tolerance is typical for bulk tantalum capacitors used in decoupling roles; the actual capacitance at the operating DC bias will shift down slightly, but the margin is adequate for most power-rail smoothing jobs. The wide operating temperature range of -55°C to 125°C means this part fits into environments where the board sees thermal cycling — think outdoor telecom, industrial control, or under-hood automotive modules.","metaTitle":"KYOCERA AVX TPSD477K006R0045 Tantalum Cap, 470 µF, 6.3 V","metaDescription":"KYOCERA AVX TPSD477K006R0045 tantalum capacitor, 470 µF ±10%, 6.3 V, 45 mOhm ESR, 2917 package.

Lower ESR means less self-heating under ripple current, so the capacitor runs cooler and delivers higher usable ripple current than a standard tantalum with 100 mOhm or more — important for output filtering in a buck converter or point-of-load regulator."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/kyocera-avx/TPSD477K006R0045","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/kyocera-avx/TPSD477K006R0045 when reusing this data.
