LKG1K392MESCAK

The LKG1K392MESCAK from Nichicon is a snap‑in, aluminum electrolytic capacitor in the LKG series engineered for audio applications. It delivers high capacitance (3.9 mF) at an 80 V rating in a radial, can snap‑in package optimized for robust board mounting.

Designed for high‑grade audio equipment (TYPE‑I / Gold Tune grade), this capacitor balances large energy storage, 120 Hz ripple handling and long‑term endurance for power supply smoothing and audio power stages where tonal integrity and stable performance are required.

Key Features

• Audio‑Grade Construction (TYPE‑I / Gold Tune) Designed specifically for high‑grade audio equipment to prioritize sound quality and tonal performance.
• High Capacitance & Voltage 3.9 mF nominal capacitance at an 80 V rated voltage provides substantial energy storage for power supply smoothing and decoupling.
• Electrical Performance Capacitance tolerance ±20% (120 Hz, 20°C) and specified tan δ = 0.25 (20°C, 120 Hz) for predictable AC behavior in audio circuits.
• Ripple Current & Leakage Low‑frequency ripple current of 3.4 A (120 Hz) and measured leakage current of 1670 µA support sustained ripple handling and predictable quiescent behavior.
• Endurance & Temperature Range Rated for 1000 hours at 85°C with operating range −40°C to +85°C, suitable for equipment subject to elevated operating temperatures.
• Mechanical & Packaging Snap‑in radial can (φ35 × 35 mm) for secure chassis/PCB mounting; supplied in tray packing for handling and assembly.
• Regulatory RoHS compliant.

Typical Applications

• High‑Fidelity Amplifier Power Supplies — Energy storage and smoothing for amplifier rails where stable supply and low noise support audio fidelity.
• Professional Audio Equipment — Power filtering and bulk decoupling in mixers, studio gear and other pro audio devices.
• Audio Power Stages and Preamp Circuits — Bulk capacitance for transient support and stable supply under dynamic audio loads.
• Rack and Chassis Mounted Audio Systems — Snap‑in can package provides reliable mechanical mounting for larger, high‑power audio modules.

Unique Advantages

• Large Energy Storage at High Voltage: 3.9 mF at 80 V supplies significant bulk capacitance for smoothing and transient support in audio power rails.
