220 µF bulk decoupling for 2.5 V rails
The TAJW227M002RNJ is a molded tantalum capacitor from the TAJ series, delivering 220 µF at 2.5 V in a 2312 (6032 Metric) surface-mount package. It is a general-purpose part suited for bulk decoupling and energy storage on low-voltage supplies. With a 300 mOhm ESR, this capacitor handles ripple currents typical of 2.5 V logic rails and point-of-load regulators without excessive self-heating. The ±20% tolerance is standard for tantalum electrolytics; the actual capacitance at 2.5 V bias and 25°C will fall between 176 µF and 264 µF.
The 2312 (6032 Metric) case measures 6.00 mm x 3.20 mm with a seated height of 1.50 mm. The manufacturer size code is W. This is a standard footprint for low-profile tantalum capacitors; the land pattern follows the JEDEC 2312 outline.
