The TAJR225M004RNJ: 2.2 µF at 4 V in an 0805 case — the 25 Ohm ESR is the limiting factor for ripple current.
The 0805 footprint is standard — no special pad geometry required beyond the datasheet land pattern.

KYOCERA AVX TAJ series, molded tantalum capacitor, 2.2 µF, 4 V rated, ±20% tolerance, 0805 case, 25 Ohm ESR, -55°C to 125°C operating range.

Design engineers need to verify electrical and mechanical fit before specifying the component.
Buyers need to quickly locate a reliable distributor to place an order.
Immediate availability is critical for production deadlines or urgent repairs.
Pricing determines budget allocation and comparison across suppliers.
If the part is unavailable, a cross-reference saves time and prevents redesign.
Lifecycle status affects long-term availability and risk of redesign for production.
