The TAJY687M004RNJ: At 680 µF and 4 V, this TAJ-series molded tantalum stores enough charge to smooth a 4 V supply rail through a 100 mA load transient without dropping below regulation — the 200 mOhm ESR limits the voltage step during the current surge.
The surface-mount footprint matches standard tantalum capacitor pads for this case size — no special via-in-pad or thermal relief required.
Design engineers need to validate fit and electrical characteristics before specifying the part.
Sourcing buyers need to find a distributor with stock to fulfill BOM lines quickly.
Buyers need cost data for budgeting and comparing suppliers.
Maintenance techs and brokers must know lifecycle status to plan replacements or avoid EOL issues.
When a part is unavailable or obsolete, buyers need an equivalent cross reference to avoid redesign.
Engineers check capacitance, voltage, tolerance, and package to ensure the part meets design requirements.
