LKG1V392MESABK

The LKG1V392MESABK is an aluminum electrolytic, snap‑in terminal capacitor from Nichicon's LKG series, specifically designed for audio applications. Its 3.9 mF capacitance at 35 V, low loss characteristic (tan δ 0.3), and audio‑grade construction make it well suited for high‑fidelity audio equipment.

Engineered for reliable operation across a broad temperature range (−40 °C to +85 °C) with a rated endurance of 1000 hours at 85 °C, this component targets designers who need stable bulk capacitance, defined ripple handling and predictable leakage characteristics in compact radial can packaging.

Key Features

• Audio‑grade design Designed for high‑grade audio equipment to prioritize high‑fidelity sound quality as part of the LKG series.
• High bulk capacitance 3.9 mF (3900 µF) capacitance provides substantial energy storage for power supply smoothing and decoupling in audio circuits.
• Rated voltage 35 V DC rating suitable for a variety of audio power rails and intermediate bus voltages.
• Low loss (tan δ) Specified tan δ of 0.3 (measurement at 120 Hz, 20 °C) for controlled dissipation in audio signal environments.
• Ripple current capability Rated ripple current of 2.3 A at 120 Hz to handle AC stress in power supply applications.
• Leakage current Specified leakage current of 1100 µA after application of rated voltage (measurement conditions per datasheet).
• Snap‑in radial can package φ25 × 35 mm can with snap‑in terminals for secure board mounting and straightforward installation.
• Temperature and reliability Operating range −40 °C to +85 °C and rated for 1000 hours at 85 °C for application lifecycle planning.
• Regulatory status RoHS compliant as specified in the product documentation.
