The TAJD477K004RNJ packs 470 µF into a standard 2917 (7343 Metric) case, making it a go-to for bulk decoupling on 3.3 V or 2.5 V rails where board space is tight.
In a switching regulator output filter, that ESR contributes to output ripple voltage — expect around 45 mV ripple per amp of ripple current.
Buyers need to budget and compare costs before purchasing.
Availability determines if the part can be sourced immediately for production.
Identifies authorized distributors to ensure genuine parts and proper warranty.
ESR affects circuit performance, especially in power supply and filtering applications.
Compliance with environmental regulations is mandatory for many designs.
When the original part is unavailable, engineers need a drop-in substitute to avoid redesign.
