The TAJA226M004RNJ: Rated 22 µF at 4 V, this molded tantalum capacitor from the TAJ series handles bulk decoupling on 3.3 V or 2.5 V supply rails where the voltage margin stays above the 4 V ceiling. The 1206 (3216 Metric) case fits standard pick-and-place lines and reflow profiles. The ±20% tolerance is typical for tantalum electrolytics — the capacitance at the low end (17.6 µF) still provides adequate charge storage for most decoupling and filtering roles on a 4 V rail.
Temperature span covers harsh environments
The molded case and tantalum construction maintain stable capacitance across the full temperature band.
