LKG1V392MESZBK

The LKG1V392MESZBK is a snap-in aluminum electrolytic capacitor from Nichicon's LKG series, engineered for audio applications. It delivers high bulk capacitance in a radial snap-in can intended for high-fidelity audio equipment and related power circuits.

Key attributes include a 3.9 mF capacitance at 35 V, a compact φ22×40L package, a rated low-frequency ripple current of 2.4 A (120 Hz), and RoHS compliance—engineered to provide stable smoothing and decoupling in audio power rails across a broad temperature range.

Key Features

• Capacitance — 3.9 mF (3900 µF) with tolerance ±20% (measured at 120 Hz, 20°C).
• Rated Voltage — 35 V nominal working voltage for DC rail applications.
• Low-Frequency Ripple Handling — 2.4 A ripple current rating at 120 Hz for sustained smoothing and bulk energy delivery.
• Leakage Current — 1100 µA specified leakage current.
• Loss Tangent (tan δ) — 0.3 measured at 20°C, 120 Hz for predictable AC loss characteristic.
• Mounting & Package — Snap-in radial can (radial, can - snap-in) in a compact φ22×40L package; supplied in tray packing.
• Temperature & Endurance — Operating range −40°C to +85°C with rated endurance of 1000 hours at 85°C.
• Regulatory — RoHS compliant.

Typical Applications

• High-Fidelity Audio Equipment — Bulk energy storage and power-rail smoothing in amplifiers and audio playback systems to support clean power delivery.
• Audio Power Supplies — DC-link and filter capacitor for linear and switching supplies in audio devices where low-frequency ripple performance matters.
• Preamp and Amplifier Circuits — Coupling/decoupling and reservoir capacitance where high capacitance in a compact snap-in package is required.
• Professional Audio Gear — Rack-mount and bench equipment that benefit from predictable tan δ and rated endurance at elevated temperatures.

Unique Advantages

• Designed for audio use — Part of the LKG series, specified for audio equipment to align electrical characteristics with sound-quality-focused applications.
• High capacitance in a compact package — 3900 µF housed in a φ22×40L snap-in can supports significant bulk storage without large board footprint.
• Sustained ripple performance — 2.4 A ripple current rating at 120 Hz addresses low-frequency smoothing demands in audio power rails.
• Measurable AC loss behavior — tan δ = 0.3 (20°C, 120 Hz) provides a defined parameter for design margins and thermal planning.
• Wide operating temperature and defined endurance — −40°C to +85°C range with 1000 hours endurance at 85°C supports predictable life under rated conditions.
• RoHS compliant — Meets RoHS directive requirements for environmental compliance.
