Product details

What the 9 Ohm ESR means for your circuit

The TAJA105K020K: At 1 µF and 20 V, the 9 Ohm ESR dominates the impedance at frequencies below a few hundred kHz — for a decoupling application, the capacitor's self-resonant frequency and the ripple current rating are both set by this resistance, not the capacitance alone.

Active production — no lifecycle concern

Listed as Active from KYOCERA AVX.

Temperature grade and mounting

The 1206 (3216 Metric) case is a common footprint; reflow profile follows standard tantalum recommendations.

Frequently asked questions

Where can I find the datasheet for TAJA105K020K?

The datasheet is available from KYOCERA AVX under the TAJ series. It covers the full capacitance/voltage/ESR matrix, reflow profile, and reliability data. We can attach it to your RFQ.

Can I use TAJA105K020K in a high-reliability circuit?

The -55 to +125 °C temperature range suits avionics and downhole environments, but this is a general-purpose molded tantalum — not a military-screened or COTS+ part. For high-reliability applications, confirm the derating guidelines for tantalum capacitors at your operating voltage and temperature.
