The ESR is 25 Ohm — that is high relative to modern low-ESR tantalum or ceramic caps. The ripple current rating is correspondingly low; this part will self-heat if placed on a rail with significant AC content. Use it on quiet DC buses or as a decoupling cap after a regulator, not on a switching converter output. ## Molded body, 0805 footprint, -55 to 125 °C The Molded construction gives a square, flat-top body that handles pick-and-place and reflow without the mechanical compliance of a conformal-coated part. The 0805 case is a standard two-pad footprint; no special land pattern or via-in-pad is needed. The operating temperature range is -55 to 125 °C — that is the full military band. This cap can sit on a satellite board, in a downhole tool, or on an avionics line-replaceable unit where the ambient cycles across the whole range.","metaTitle":"TAJR474M020SNJ KYOCERA AVX 0.47 µF 20 V Molded Tantalum Cap","metaDescription":"TAJR474M020SNJ from KYOCERA AVX. 0.47 µF, 20 V, ±20% tolerance, 0805 case, -55 to 125 °C.

That is a high value — this cap is not designed for low-impedance decoupling on a fast-switching rail. It works as a bulk bypass on a quiet DC bus or a coupling cap where the series resistance does not affect the signal path."},{"question":"What is the closest pin-compatible alternative to TAJR474M020SNJ?","answer":"No official second-source is listed. In the TAJ series, the case size (0805, code R) and voltage (20 V) are the matching constraints. Kemet T491 and Vishay 593D series offer molded tantalum caps in 0805 at similar ratings — check the ESR and tolerance before substituting, as those families often spec lower ESR values."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/kyocera-avx/TAJR474M020SNJ","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/kyocera-avx/TAJR474M020SNJ when reusing this data.
