4.7 µF, 25 V molded tantalum — bulk decoupling for a 25 V rail
The TAJW475M025RNJ is a 4.7 µF ±20% molded tantalum capacitor from the KYOCERA AVX TAJ series, rated at 25 V with a 1.2 Ohm ESR. It comes in a 2312 (6032 Metric) surface-mount package, size code W, standing 1.50 mm max seated height. This is a general-purpose part — no low-ESR or high-reliability screening.
Military temperature range — -55 to +125 °C
At 125 °C, the DC leakage current rises and the capacitance may drift near the ±20% tolerance edge — derate the working voltage by 50% above 85 °C per standard tantalum practice.
