Product details

4.7 µF, 10 V, 5 ohm ESR — bulk decoupling on a 10 V rail

This TAJA475M010HNJ is a 4.7 µF molded tantalum capacitor from the TAJ series, rated at 10 V with ±20% tolerance. The 5 ohm ESR at 100 kHz tells you the self-heating under ripple current — for a 10 V rail pulling a few hundred mA of ripple, the internal temperature rise stays manageable, but the ESR limits the usable ripple current to roughly 350 mA RMS before the cap exceeds its 125°C ceiling. The 1206 (3216 metric) footprint is a standard SMD pad shared across multiple tantalum and ceramic suppliers, so a BOM swap to a different brand doesn't require a layout change.

Rated lifetime is 2000 hours at 125°C — that's the accelerated test condition. In a 85°C ambient, the expected life roughly doubles per 10°C drop, so a cap on a 10 V rail running at 85°C ambient sees well over 8000 hours before the ESR or leakage drift out of spec.

KYOCERA AVX lists the TAJA475M010HNJ as Active — no NRND or EOL flag.

Frequently asked questions

What is the ESR of TAJA475M010HNJ?

5 ohm typical at 100 kHz. This ESR limits the ripple current rating — for a 10 V rail with 350 mA ripple, the internal temperature rise stays within the 125°C ceiling. Higher ripple currents require a lower-ESR grade or a larger case size.

What is the equivalent part for TAJA475M010HNJ?

No pin-compatible equivalent is listed by KYOCERA AVX. The TAJ series includes other 4.7 µF 10 V parts with different ESR or tolerance grades, but the TAJA475M010HNJ is the ±20%, 5 ohm variant. Any replacement must match the 1206 footprint, 10 V rating, and ESR to maintain the same decoupling performance.
