LKG1H392MESABK

The LKG1H392MESABK is an aluminum electrolytic capacitor in Nichicon's LKG series, featuring a snap‑in radial can package and a 3.9 mF (3900 µF) capacitance at a 50 V rating. The LKG series is developed for audio equipment, prioritizing high‑fidelity sound quality and stable power filtering where audible performance matters.

This part is offered with a ±20% capacitance tolerance, a tangent of loss angle (tan δ) of 0.3, an operating temperature range of −40 °C to +85 °C, and a specified endurance of 1000 hours at 85 °C. Note: this part is listed as End of Life/Discontinued—availability may be limited.

Key Features

• Capacitance — 3.9 mF (3900 µF) for bulk energy storage and supply smoothing in audio power rails.
• Rated Voltage — 50 V rating suitable for mid‑voltage audio supply designs.
• Tolerance & Loss — ±20% capacitance tolerance and tan δ = 0.3 (measured at 120 Hz, 20 °C) to characterize AC loss behavior.
• Package & Mounting — Snap‑in radial can (lug / snap‑in terminal) for secure board retention and mechanical stability in through‑hole assemblies.
• Temperature & Endurance — Operating range −40 °C to +85 °C with endurance specified as 1000 hours at 85 °C under rated voltage.
• Ripple Current — 3 A at 120 Hz, suitable for filtering and smoothing duties at typical audio frequencies.
• Polarized — Electrolytic polarized capacitor intended for DC power applications.
• RoHS Compliant — Meets RoHS directive requirements.

Typical Applications

• High‑Fidelity Audio Amplifiers — Bulk and decoupling capacitance for analog amplification stages and power supply smoothing where audio performance is critical.
• Audio Power Supply Filtering — Energy storage and ripple reduction on DC rails feeding preamplifiers and power amps.
• Professional Audio Equipment — Use in mixers, studio rack gear, and other pro audio modules that require reliable, high‑capacity filtering.
