Product details

Molded tantalum, 25 V rated, 1206 footprint

The TAJA105M025HNJ: This is a KYOCERA AVX TAJ series molded tantalum capacitor, 1 µF ±20% tolerance, rated at 25 V. The 1206 (3216 Metric) surface-mount package fits standard pick-and-place assembly. The 8 Ohm ESR at 100 kHz sets the ripple current ceiling — for a given ripple current, the I²R loss heats the part, and the 2000-hour lifetime at 125 °C assumes the internal temperature stays within the rated limit.

The molded construction resists moisture and mechanical stress better than uncoated chips.

Frequently asked questions

Is TAJA105M025HNJ RoHS compliant?

The part is listed with General Purpose features; RoHS compliance is standard for the TAJ series, but confirm with the specific date code at order. Request the RoHS certificate of compliance with your RFQ.

Can I use a 16 V capacitor instead of 25 V for this part?

Derating is standard practice for tantalum capacitors — a 16 V part on a 12 V rail may work, but the 25 V rating provides margin against voltage spikes and inrush. Substituting a lower voltage rating increases failure risk; stay with the 25 V rating unless the circuit is re-characterized.
