Molded tantalum chip for higher-voltage rails
The TAJB105K050RNJ is a KYOCERA AVX TAJ series molded tantalum capacitor, rated 1 µF at 50 V with ±10% tolerance. The 50 V rating provides margin on common power rails, and the molded case suits automated assembly. The 7 ohm ESR is a key parameter for ripple current handling — higher ESR means more self-heating under AC ripple, so derate the ripple current accordingly in your design.
Temperature range and field-fit
The 1411 (3528 Metric) case with B size code is a common footprint; the 0.138" x 0.110" body and 0.083" seated height fit standard pick-and-place nozzles.
