Active production — no last-time-buy window
TAJC155K050HNJ carries an active product status from KYOCERA AVX — the manufacturer continues to support this order code without an end-of-life notice.
Series identification — verify before BOM commit
The series field is blank in the available specification data. Before placing this order code on a BOM, cross-check the reel label or manufacturer datasheet to confirm the dielectric family (tantalum, niobium oxide, or polymer) and the voltage/capacitance rating match the design intent. Tantalum capacitors require different derating rules than standard MLCCs — a mismatch here could affect reliability in power-supply or decoupling roles.
