Molded tantalum for harsh environments
The TAJC475K020SNJ is a molded tantalum capacitor from the TAJ series, rated at 4.7 µF and 20 V with ±10% tolerance. The 1.4 Ohm ESR sets the ripple current ceiling and self-heating limit — for a 100 kHz switching regulator output, the ripple current should stay below the capacitor's rated ripple to keep the core temperature within the -55 to 125 °C operating range.
2312 case, size code C
The 2312 (6032 Metric) case measures 6.00 mm x 3.20 mm with a seated height of 2.80 mm max. The manufacturer size code C corresponds to this footprint. Surface-mount assembly on a standard FR-4 board — the pad layout follows the 2312 recommended land pattern; no via-in-pad required.
