LKG1E392MESAAK

The LKG1E392MESAAK is a snap‑in, polarized aluminum electrolytic capacitor from Nichicon’s LKG series, specified at 3.9 mF (3900 µF) and 25 V. It is part of the TYPE‑I (Gold Tune) audio grade lineup and is designed for use in high‑fidelity audio equipment where stable bulk capacitance and reliable power filtering are required.

Key value comes from a compact snap‑in can package (φ25 × 20 mm length), high ripple handling at 120 Hz, and endurance defined for 1000 hours at 85°C—attributes that support robust audio power supply and filtering applications.

Key Features

• Capacitance & Voltage — 3.9 mF (3900 µF) rated at 25 V with ±20% tolerance for bulk energy storage and supply decoupling.
• Audio‑Grade Construction — TYPE‑I (Gold Tune) designation from the LKG series, intended for high tone quality in audio equipment.
• Package & Mounting — Snap‑in, radial can package (φ25 × 20 mm) for secure chassis or board mounting in power assemblies.
• Ripple Current — 1.55 A ripple current rating at 120 Hz, suitable for smoothing and filtering in audio power supplies.
• Leakage & Loss — Specified leakage current around 930 µA and tan δ of 0.30, enabling predictable loss and leakage behavior in designs.
• Temperature & Endurance — Operating range −40°C to +85°C and endurance of 1000 hours at 85°C per the series specification.
• RoHS Compliance — Compliant to RoHS directives for environmental regulatory requirements.
• Low‑temperature Stability — Series characteristics include defined impedance ratios: Z(−25°C)/Z(+20°C) ≤ 4 and Z(−40°C)/Z(+20°C) ≤ 12 for predictable performance at low temperatures.
• Identification — Marked with gold color lettering on a black sleeve as per series marking convention.

Typical Applications

• High‑Fidelity Amplifiers — Bulk filtering and power smoothing in amplifier power rails to support stable audio output.
• Audio Power Supplies — Energy storage and ripple suppression for preamplifiers, DAC power stages, and other audio supply domains.
• Professional Audio Equipment — Use in mixers, studio components, and consumer high‑grade audio devices where tonal quality and endurance are required.

Unique Advantages

• Audio‑Focused Grade: TYPE‑I (Gold Tune) construction targets high tone quality for audio equipment designs.
• High Capacitance in Compact Can: 3900 µF in a φ25 × 20 mm snap‑in package enables dense energy storage in space‑constrained audio assemblies.
• Robust Ripple Handling: 1.55 A ripple current (120 Hz) helps maintain low ripple on power rails under typical audio loading.
• Designed for Elevated Use Temperatures: 1000‑hour endurance at 85°C provides a defined long‑term performance baseline for warm operating environments.
• Predictable Loss and Leakage: Specified tan δ and leakage current support reliable circuit modeling and margining for audio designs.
• Regulatory Compliance: RoHS conformity supports designs targeting regulated markets and manufacturing flows.
