100 µF bulk decoupling for a 10 V rail — what the ESR tells you
The TAJC107K010RNJ: This is a 100 µF tantalum capacitor rated at 10 V with a 1.2 Ohm ESR. The 1.2 Ohm ESR means the ripple current capability is modest; at 100 kHz, the impedance is dominated by the ESR, so this cap is best suited for bulk decoupling where the ripple frequency is below a few hundred kilohertz, not for high-frequency bypass where you would parallel a ceramic.
The operating temperature range spans -55 to +125 °C, which is the military temperature band.
The product status is Active.
