LKG1E392MESACK

The LKG1E392MESACK is an aluminum electrolytic, snap‑in terminal capacitor from Nichicon’s LKG series, engineered for audio equipment. It delivers 3900 µF at 25 V with design priorities aligned to high‑grade audio applications and high fidelity sound quality.

Built for power‑handling and stability in AV and professional audio circuits, this radial can‑style capacitor combines a compact φ25 × 45 mm package with a 2.8 A low‑frequency ripple current rating and a 1000‑hour endurance at 85°C.

Key Features

• Capacitance & Voltage  3900 µF rated capacitance at 25 V with a tolerance of ±20% (measured at 120 Hz, 20°C).
• Audio‑Grade Series Design  Part of Nichicon’s LKG series, developed for high‑grade audio equipment and prioritizing fidelity in sound reproduction.
• Loss Angle (tan δ)  Specified tanδ of 0.22 (measurement condition: 20°C, 120 Hz), giving a defined dissipation characteristic for audio applications.
• Ripple Current Capability  Low‑frequency ripple current rated at 2.8 A (120 Hz), supporting applications with significant power supply ripple demands.
• Leakage Current  Specified leakage current of 930 µA, measured after voltage application conditions consistent with the datasheet method.
• Endurance & Temperature Range  Rated for 1000 hours at 85°C; operational temperature range from −40°C to +85°C.
• Package & Mounting  Snap‑in radial can (φ25 × 45 mm), tray packaging for board‑level assembly and secure snap‑in mounting.
• Environmental Compliance  RoHS‑compliant construction in line with the LKG series declaration.

Typical Applications

• High‑grade Audio Equipment  Suited for use in audio systems where the LKG series’ design focus on fidelity is required.
• Power Supply Filtering in Amplifiers  Large capacitance and 2.8 A ripple rating make it appropriate for smoothing and decoupling in audio power rails.
• Professional AV and Studio Gear  Rugged operating range (−40°C to +85°C) and 1000‑hour endurance at 85°C support demanding pro‑audio environments.

Unique Advantages

• Engineered for audio fidelity: The LKG series prioritizes high‑tone quality and sound reproduction, making this part suitable for high‑grade audio designs.
• High ripple handling: 2.8 A low‑frequency ripple current rating at 120 Hz helps manage power‑supply ripple in amplifier and AV circuits.
• Clearly specified electrical behavior: Measured tanδ (0.22) and defined leakage current (930 µA) provide predictable dissipation and leakage characteristics for design validation.
• Robust thermal endurance: 1000 hours at 85°C endurance rating supports reliable long‑term operation within the specified temperature range.
• Compact snap‑in form factor: φ25 × 45 mm radial can with snap‑in terminals enables secure board mounting while minimizing footprint.
• RoHS compliant: Meets RoHS directive requirements as declared for the LKG series.
