Product details

What this molded tantalum capacitor delivers

The TAJA155M020RNJ is a molded tantalum capacitor from the TAJ series, offering 1.5 µF capacitance with ±20% tolerance at a 20 V rated voltage in a standard 1206 footprint. Its 6.5 Ohm ESR is typical for a small-case tantalum at this capacitance and voltage — expect higher ripple-induced heating than a low-ESR ceramic, so derate for ripple current in power-supply output filters.

1206 (3216 Metric) case, size code A, measuring 3.20 mm x 1.60 mm with a seated height of 1.80 mm max — a common footprint shared with ceramic capacitors, easing layout reuse.

Frequently asked questions

Can I replace TAJA155M020RNJ with a ceramic capacitor?

A ceramic capacitor of the same capacitance and voltage rating (e.g., X7R or X5R in 1206) will have much lower ESR (milliohms vs 6.5 Ohm) and no polarity, but also a strong DC bias derating — the effective capacitance at 20 V may drop by 50% or more. The tantalum holds its full 1.5 µF across the voltage range, so substitution requires verifying the in-circuit capacitance under bias.
