The TAJE157M020RNJ is a molded tantalum capacitor from the TAJ series, rated 150 µF at 20 V with ±20% tolerance and a 300 mOhm equivalent series resistance (ESR). The 300 mOhm ESR is the key filtering spec: at 150 µF and 20 V, this part can handle moderate ripple current in a power rail decoupling role without excessive self-heating.
Military temperature range and E-case footprint
The E-case (2917 / 7343 metric) measures 7.30 mm x 4.30 mm with a seated height of 4.30 mm — a standard footprint that matches many 2917 tantalum pads on existing boards.
