The TAJC157K006RNJ: That means it is safe to design into new builds and requalify without a looming obsolescence deadline.
150 µF capacitance with a 6.3 V rated voltage — this is the classic bulk decoupling value for a 3.3 V or 1.8 V rail that needs a low-impedance reservoir. The ±10% tolerance keeps the actual capacitance tight enough for most filtering and hold-up jobs.
1.3 Ohm ESR — what it means for ripple and heat
1.3 Ohm ESR at 25 °C sets the ripple current ceiling. At 100 kHz, the capacitor's self-heating rises with I² × ESR; a 500 mA ripple current pushes about 325 mW of internal dissipation. That heat has to escape through the 2312 (6032 Metric) case, so the board copper area around the pad matters more than with a low-ESR polymer cap.
Molded case, C size, surface mount
Molded construction in the C case code (6.00 mm × 3.20 mm footprint, 2.80 mm seated height) — the package is self-aligning during reflow and the molded body gives consistent stand-off for cleaning. Surface mount, tape-and-reel delivery for automated pick-and-place.
-55 to +125 °C — full military temperature band
No derating needed down to -55 °C; at +125 °C the voltage derating per MIL-PRF-55365 guidelines still applies.
