The TAJT475K020RNJ is a molded tantalum capacitor from the TAJ series, rated 4.7 µF at 20 V with ±10% tolerance. The 3.1 Ohm ESR sets the ripple current capability and self-heating limit — for a 12 V rail with 100 mV ripple, this capacitor handles the ripple current without exceeding the 125°C ceiling.
The molded case (1411 / 3528 Metric) is a standard footprint for surface-mount assembly — 3.50 mm x 2.80 mm, 1.20 mm seated height.
Design engineers need to verify electrical and mechanical specifications before using the part.
Sourcing buyers need to find authorized distributors to purchase the part.
Buyers compare pricing across distributors for budget and BOM cost estimation.
Immediate availability is crucial for production deadlines and avoiding lead times.
Engineers and buyers need to know alternatives for supply chain flexibility or obsolescence.
Maintenance techs and buyers need to confirm tape and reel packaging for assembly equipment.
