Molded tantalum for wide-temp bulk decoupling
The TAJX157M010RNJ is a 150 µF molded tantalum capacitor rated at 10 V with a 300 mOhm ESR, built for surface-mount bulk decoupling across the full -55°C to 125°C military temperature range. The 300 mOhm ESR defines the ripple current ceiling — at 125°C ambient the self-heating from ripple must stay below the derating curve, so the actual AC current the cap can handle is lower than the DC rating suggests.
2917 footprint and polarity marking
The 2917 (7343 Metric) case measures 7.30 mm x 4.30 mm with a seated height of 1.50 mm max. Molded tantalum caps are polarised — the anode (+) is marked on the top face; reverse voltage beyond 1 V at rated temperature can cause catastrophic failure.
