The TAJB225K020RNJ: This is a 2.2 µF tantalum capacitor rated at 20 V with ±10% tolerance – the primary selection parameters for any bulk decoupling or filtering position on a 12 V or 5 V rail.
Housed in the B case size (1411 / 3528 Metric), measuring 3.50 mm x 2.80 mm with a seated height of 2.10 mm max – a common footprint that fits standard pick-and-place and reflow profiles.
Validates that the part meets the design requirement before purchase.
Determines immediate availability for production or replacement needs.
Impacts budget and BOM cost, drives purchase decision.
Ensures physical fit on the PCB footprint before layout or replacement.
Critical if the part is obsolete, unavailable, or an alternative is needed for cost/lead time.
Directs the buyer to a distributor that stocks the part, enabling the transaction.
