LKG1H472MESYAK

The LKG1H472MESYAK is a snap‑in, radial aluminum electrolytic capacitor from Nichicon’s LKG series, specified at 4.7 mF (4700 µF) and 50 V. It is part of the LKG family designed for high‑grade audio equipment and provides a compact, polarized energy storage solution for power filtering and decoupling in audio and related electronics.

Key value comes from audio‑focused design and clear electrical specifications: high ripple handling (2.75 A at 120 Hz), defined leakage current, and an endurance rating of 1000 hours at 85 °C—making it suitable for projects requiring stable performance within -40 °C to 85 °C.
