The 20 Ohm ESR is the headline spec for a buyer evaluating this part for decoupling or filtering. For a 1 µF capacitor at 20 V, that ESR is typical for a small-case tantalum — it limits ripple current handling and high-frequency bypass effectiveness. If your circuit needs sub-ohm ESR at 1 µF, you are looking at a ceramic or polymer electrolytic, not this part. ## Active status — no LTB pressure For a BOM line that calls out this exact order code, supply continuity is not a concern — the part is in regular production and sourced through independent distribution per RFQ. The molded construction provides mechanical protection and moisture resistance consistent with that range.","metaTitle":"TAJR105K020YNJ KYOCERA AVX 1 µF 20 V Tantalum Capacitor 0805","metaDescription":"TAJR105K020YNJ molded tantalum capacitor, 1 µF ±10%, 20 V, 0805 case, -55°C to 125°C, 20 Ohm ESR.

This part is not suited for high-frequency decoupling or low-ESR filtering applications. It is better matched to bulk storage, timing circuits, or coupling where ESR is not the primary constraint."},{"question":"Can TAJR105K020YNJ be used in automotive designs?","answer":"The evidence does not list AEC-Q200 or automotive qualification. The -55°C to 125°C range overlaps automotive temperature grades, but without an AEC-Q mark, it is not qualified for automotive PPAP. Use a certified automotive-grade tantalum for under-hood or safety-critical applications."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/kyocera-avx/TAJR105K020YNJ","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/kyocera-avx/TAJR105K020YNJ when reusing this data.
