Molded tantalum, 10 µF at 50 V — the bulk decoupling fit
The ±10% tolerance covers the production spread; the 50 V rating gives headroom on a 48 V bus or a 24 V rail with margin for transients.

KYOCERA AVX TAJ series, Molded tantalum capacitor, 10 µF ±10%, 50 V rated, 2917 (7343 Metric) case, 800 mOhm ESR @ 100 kHz.

The ±10% tolerance covers the production spread; the 50 V rating gives headroom on a 48 V bus or a 24 V rail with margin for transients.
The suffix ANJ vs AN typically indicates a packaging or termination finish variant (e.g., tape-and-reel vs bulk, or RoHS compliance level). The core electrical ratings — 10 µF, 50 V, ±10%, 800 mOhm ESR — are identical. Confirm the specific suffix with the manufacturer datasheet to ensure BOM compatibility for your assembly process.
The part is listed under General Purpose features, and the TAJ series from KYOCERA AVX is typically RoHS-compliant. Verify the specific date-code compliance against your local RoHS exemption list — the manufacturer's datasheet or a compliance certificate can confirm the exact termination finish.
