Molded tantalum, 2.2 µF at 35 V — B-case footprint
TAJB225K035RNJ is a molded tantalum capacitor from the KYOCERA AVX TAJ series, rated 2.2 µF at 35 V with ±10% tolerance. The 4.2 ohm ESR means this part suits bulk decoupling and moderate-ripple filtering but is less effective for high-frequency bypass where sub-ohm ESR is typical. The 1411 (3528 Metric) case with B code defines a 3.50 mm x 2.80 mm footprint and 2.10 mm seated height — confirm the land pattern matches your PCB layout before committing the BOM.
Active production with wide temperature range
This is a common spec for avionics, satellite, and downhole instrumentation where the capacitor sees the full temperature swing unpowered or biased.
