The TAJE158M002RNJ is a molded tantalum capacitor from the KYOCERA AVX TAJ series, delivering 1500 µF at 2.5 V in the standard 2917 (7343 Metric) E-case package. A 1500 µF cap with 200 mOhm ESR yields a zero at roughly 530 Hz — the control loop sees that pole-zero pair, so the compensation network on a buck converter should account for it.
The molded case provides mechanical stability across thermal cycling — no conformal-coat compatibility issues with the epoxy body.
The part is listed as General Purpose and is produced under KYOCERA AVX's standard RoHS-compliant process for the TAJ series. No separate RoHS certificate is required — the series datasheet covers compliance. Confirm with your specific date-code lot at RFQ if you need a formal statement.
The TAJ series is a commercial-grade molded tantalum line, not a MIL-spec or COTS+ part. For avionics or satellite use, you would typically step up to a surge-tested or Weibull-graded series (e.g., AVX TPS or CWR). The -55°C to 125°C range and molded construction are favourable, but no AEC-Q100 or MIL-PRF-55365 qualification is cited for this order code.
