The TAJD107M020HNJ is a 100 µF tantalum capacitor rated at 20 V, from KYOCERA AVX's Specialty Capacitors line. The 100 µF value suits bulk decoupling on power rails that need local energy storage — think a 3.3 V or 5 V rail feeding a small MCU or FPGA core where the supply droop during transient loads must stay under 50 mV.
D case footprint and Tape & Reel delivery
The D case size gives a compact footprint for dense PCB layouts. Supplied on Tape & Reel (TR), it feeds directly into a pick-and-place machine.
