The TAJR225M010RNJ: The 15 Ohm ESR limits ripple current handling — for a 100 kHz ripple of 100 mA, self-heating is I² × ESR = 0.15 W, which is within the 0805 package's dissipation capability but leaves little margin at 125°C ambient.
The molded 0805 case (2.05 mm × 1.30 mm footprint) is a standard surface-mount size — no special reflow profile beyond the usual tantalum pre-bake for moisture sensitivity.
Engineers need to verify fit and compatibility.
Buyers need to compare costs for BOM.
Availability affects lead time and production schedule.
Sourcing buyers need authorized distributors.
Designers may need alternatives for second sourcing.
Regulatory compliance is critical for many applications.
