Capacitance, voltage, and package for BOM fit
The TAJA156M010RNJ is a 15 µF ±20% tantalum capacitor rated at 10 V DC, housed in a standard 1206 (3216 Metric) surface-mount package. This is the footprint you need to match against the existing pad layout on your board — the 3.20 mm x 1.60 mm body with a seated height of 1.80 mm fits most low-profile decoupling slots.
ESR and temperature grade for harsh environments
With a 3.2 Ohm ESR, this part handles moderate ripple current but is not intended for high-frequency, low-impedance decoupling on fast-switching rails — the ESR limits the capacitor's ability to shunt AC noise.
No pin-compatible direct replacement is on file, but other TAJ-series capacitors in the same case size and voltage rating share the same footprint.
