PCH1K470MCL1GS

The PCH1K470MCL1GS is a conductive‑polymer aluminum solid electrolytic chip capacitor in an SMD can package designed for high‑voltage, high‑temperature applications. With a 47 µF capacitance at a rated voltage of 80 V, this polarized capacitor delivers low equivalent series resistance (33 mΩ at 100 kHz) and strong ripple‑current capability for demanding power systems.

Engineered for reliability, the PCH series supports long life (4000 hours at 135°C), AEC‑Q200 qualification, and lead‑free reflow soldering up to a 260°C peak. Typical use cases include automotive electronic modules and high‑temperature power electronics where voltage handling, thermal endurance, and low ESR are required.
