Product details

The TAJA105K025RNJ: This is a molded tantalum capacitor from the TAJ series, 1 µF ±10% at 25 VDC, with an ESR of 8 Ohm. The 8 Ohm ESR is the key derating parameter: for a given ripple current, I²R heating is fixed, so in a power-supply output filter the capacitor's temperature rise limits the ripple current to about 250 mA RMS before self-heating becomes a concern. For decoupling or timing applications where ripple is low, the ESR is less of a constraint.
