The 300 mOhm ESR sets the ripple current ceiling — at 100 kHz, the self-heating from ripple current stays within the 125°C max if the RMS current is kept under ~1.1 A. ## 2917 case, Y code — footprint and height constraints The 2917 (7343 Metric) case measures 7.30 mm x 4.30 mm with a seated height of 2.00 mm max. The Y size code is the standard 2.0 mm height variant in the TAJ family — it fits under a 2.5 mm board-to-shield gap with 0.5 mm clearance. Surface-mount reflow profile follows the standard tantalum profile: peak 260°C, ramp rate ≤3°C/s, soak above 217°C for 60-90 seconds. ## Active production — no EOL notice on record KYOCERA AVX lists the TAJY227K002RNJ as Active. No last-time-buy window or end-of-life notice has been published. Tantalum capacitor supply is sensitive to raw-material availability — lead times can stretch during allocation cycles.","metaTitle":"TAJY227K002RNJ KYOCERA AVX 220 µF 2.5 V Tantalum Cap, 2917","metaDescription":"TAJY227K002RNJ molded tantalum capacitor, 220 µF ±10%, 2.5 V, 300 mOhm ESR, -55 to 125°C. 2917 case, Y code.

This ESR value determines the ripple current rating and self-heating — for a given ripple current, the power dissipation is I² × 0.3 Ω. Keep the RMS ripple current below ~1.1 A to stay within the 125°C max operating temperature."},{"question":"Can TAJY227K002RNJ be replaced with a polymer capacitor?","answer":"A polymer capacitor in the same 2917 case will typically offer lower ESR (10-50 mOhm) but lower capacitance per voltage — a 220 µF polymer at 2.5 V is rare; most polymer caps at this case size are 100-150 µF. The trade-off is ripple current handling (polymer wins) vs bulk energy storage (tantalum wins). Pin-compatible in footprint, but the ESR difference may change the loop stability of the regulator."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/kyocera-avx/TAJY227K002RNJ","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/kyocera-avx/TAJY227K002RNJ when reusing this data.
