Product details

The TAJX157K006RNJ: This is a molded tantalum capacitor from the TAJ series, rated 150 µF at 6.3 V with ±10% tolerance. The 2917 (7343 Metric) case measures 7.30 mm x 4.30 mm with a seated height of 1.50 mm — a standard low-profile footprint for power-rail smoothing and hold-up capacitance on dense PCBs.

ESR and temperature range for the BOM

900 mOhm ESR at 100 kHz sets the ripple current ceiling — in a 3.3 V to 1.8 V LDO output filter, the self-heating from ripple current stays within the 125°C max rating when the RMS current is kept below the derating curve.

Frequently asked questions

What is the closest pin-compatible alternative to TAJX157K006RNJ in the TAJ series?

Within the same TAJ series, any 150 µF, 6.3 V, 2917 case tantalum capacitor with the same ±10% tolerance and 900 mOhm ESR is a direct drop-in. The manufacturer size code X is specific to this case size and height. No official cross-reference is published, but other TAJ series parts with matching capacitance, voltage, and case code are functionally equivalent for the same footprint.
