Active production — mil-temp tantalum for DC rails
33 µF bulk capacitance at 6.3 V rated voltage suits 3.3 V and 5 V supply decoupling where the ripple current is modest — the 2.5 Ohm ESR limits the capacitor's ability to absorb fast transients, so keep it on the output of a linear regulator or as a local reservoir after a low-frequency switching converter. The ±10% tolerance holds the capacitance spread tight enough for timing circuits in RC oscillators or filter poles where a 20 % part would drift the corner frequency out of specification.
1411 / 1210 case — footprint and height constraints
The 3.50 mm x 2.80 mm footprint with a seated height of 1.20 mm fits under a 1.5 mm board-to-shield clearance — common in handheld and portable equipment where the PCB stack is tight.
