Capacitance, voltage, and ESR — the BOM-fit numbers
The TAJB155K025H is a molded tantalum capacitor from the TAJ series, rated at 1.5 µF capacitance with ±10% tolerance and a 25 V voltage rating. The 5 Ohm ESR at 25 V is typical for this case size and capacitance — it sets the ripple current ceiling and self-heating, so for a 25 V rail bypass, the 5 Ohm ESR is well within the margin for a 1.5 µF decoupling cap.
The full military temperature range means the capacitance and ESR are specified across the entire span, not just at room temperature.
No direct replacement or second-source is recorded, but the TAJ series includes many capacitance/voltage combinations in the same B case size if a value change is needed.
