4.7 µF, 6.3 V — molded tantalum for low-voltage rails
The TAJA475K006RNJ is a molded tantalum capacitor from the KYOCERA AVX TAJ series, rated at 4.7 µF with ±10% tolerance and a 6.3 V working voltage. The 6 Ohm ESR (equivalent series resistance) sets the ripple current ceiling and output impedance for decoupling a sub-10 V rail — a common fit for 3.3 V or 5 V supply filtering in portable or embedded gear.
1206 case, surface-mount — rework-friendly footprint
Housed in a 1206 (3216 Metric) molded case, 3.20 mm x 1.60 mm footprint with a seated height of 1.80 mm max. The molded body and standard pad layout mean a hot-air rework station can swap this part without removing adjacent components — a practical advantage for repair benches and prototype spins.
Active — still in production for new builds
Temperature range — -55 to +125 °C
The full military-temperature band means it holds capacitance and ESR through cold-start and high-ambient conditions — avionics, downhole instrumentation, or outdoor telecom gear where the board sees seasonal extremes.
