The TAJD106M050RNJ: This is a 10 µF molded tantalum capacitor rated at 50 V with an 800 mOhm ESR, in the D-case (2917 metric) package. The 50 V rating gives a healthy derating margin on a 12 V or 24 V rail — tantalum caps need 50% voltage derating for reliable operation, so this part comfortably covers a 25 V bus. The 800 mOhm ESR limits ripple current to roughly 250 mA RMS at 85°C; above that the internal temperature rise accelerates wear-out.
Active production — no end-of-life signal
No last-time-buy window to chase.
The molded case construction handles the thermal cycling without cracking the dielectric — a known failure mode in conformal-coated tantalums under rapid temperature change.
