What this 2.2 µF tantalum does for your rail
The TAJA225M025HNJ is a molded tantalum capacitor from the TAJ series, 2.2 µF at 25 V with ±20% tolerance. The 7 Ohm ESR dominates impedance at high frequencies, limiting ripple attenuation per stage.
The molded case handles humidity better than conformal-coated chips; no additional potting needed for most sealed assemblies.
No pin-compatible equivalent from another manufacturer is documented; the TAJ series is the reference.
