LKG1H392MESCBK

The LKG1H392MESCBK is an aluminum electrolytic, snap‑in terminal capacitor from Nichicon’s LKG series, specified at 3900 µF and 50 V. It is designed for high‑grade audio equipment with an emphasis on high‑fidelity sound and suitability for HD audio applications.

This snap‑in, radial can package provides a compact power reservoir for audio circuits while delivering rated endurance and ripple performance for demanding audio power supplies and amplifier stages.

Key Features

• Audio‑focused design  Designed for high‑grade audio equipment and HD audio applications where fidelity is a priority.
• Capacitance & voltage  3900 µF nominal capacitance at a rated voltage of 50 V, with capacitance tolerance ±20%.
• Snap‑in radial package  Snap‑in terminal mounting in a radial can (φ35 × 25 mm case), enabling secure panel or chassis mounting for power supply reservoirs.
• Operating temperature & endurance  Specified for −40°C to +85°C operation with 1000 hours endurance at 85°C under rated voltage.
• Ripple current capability  Rated ripple current 3.15 A at 120 Hz to support smoothing and decoupling in audio power stages.
• Polarized construction  Polarized electrolytic type suitable for DC power filtering and reservoir applications.
• RoHS compliant  Complies with the RoHS directive (2011/65/EU, (EU)2015/863).
• Leakage current specification  Leakage current meets the series specification: after 5 minutes at rated voltage and 20°C, leakage ≤ 3√CV (µA) as per the datasheet.

Typical Applications

• High‑grade audio amplifiers  Acts as a power reservoir and smoothing capacitor to support amplifier output stages in premium audio equipment.
• HD audio systems  Provides bulk energy storage and low‑frequency filtering where preservation of audio fidelity is required.
• Professional audio equipment  Useful in mixers, preamps, and studio gear that require reliable DC filtering and stable performance over time.

Unique Advantages

• Audio‑first engineering  Part of the LKG series developed with priority on high‑fidelity sound quality for HD audio use.
• High energy density at 50 V  3900 µF in a φ35 × 25 mm can provides substantial capacitance for power smoothing within a compact footprint.
• Snap‑in mounting for secure installation  Snap‑in radial can simplifies integration into chassis and power assemblies where vibration resistance and mechanical stability matter.
• Temperature and endurance rated  Rated −40°C to +85°C and qualified for 1000 hours at 85°C under rated voltage for predictable life in heated enclosures.
• Designed for ripple handling  3.15 A ripple current rating at 120 Hz supports dynamic power demands typical of audio power supplies.
• Standards‑aware manufacture  RoHS compliance and datasheet‑defined leakage and endurance limits support regulatory and reliability requirements.
