22 µF at 10 V — bulk decoupling and filtering fit
The TPST226K010R0800: Rated 22 µF at 10 V with ±10% tolerance, this molded tantalum capacitor provides the bulk capacitance needed for power rail decoupling, ripple filtering, and hold-up energy storage in low-voltage DC circuits. The 800 mOhm ESR (Equivalent Series Resistance) governs the ripple current rating and self-heating under AC load — a lower ESR means less internal temperature rise for the same ripple, which extends operational life in high-frequency switching regulators.
Molded TPS series — surface-mount footprint and profile
Surface-mount construction with Tape & Reel packaging supports standard reflow soldering on automated pick-and-place lines, eliminating the need for through-hole hand-soldering in volume production. The molded encapsulation provides consistent case dimensions and mechanical robustness against board flexure during assembly and field vibration.
