LKG1J392MESCAK

The LKG1J392MESCAK is a Nichicon LKG series aluminum electrolytic capacitor in a snap‑in terminal configuration, optimized for audio equipment. It provides 3.9 mF capacitance at a 63 V rated voltage with a polarized design suited to power‑stage and signal‑chain applications in high‑grade audio systems.

Designed with audio performance in mind, this capacitor combines a low loss tangent specification and a high low‑frequency ripple current rating with a compact φ35 × 25 mm package and snap‑in mounting for secure board assembly. It is RoHS compliant and supplied in tray packing.

Key Features

• Core electrical — 3.9 mF capacitance rated at 63 V with ±20% tolerance (120 Hz, 20°C), providing bulk energy storage for audio circuitry.
• Low loss characteristic — tan δ specified at 0.3 (measured at 20°C, 120 Hz), supporting fidelity-focused designs that prioritize low dissipation.
• High low‑frequency ripple capability — Rated low‑frequency ripple current of 3.0 A at 120 Hz for robust handling of power stage ripple in audio applications.
• Leakage and polarization — Polarized capacitor with a specified leakage current of 1480 µA after initial voltage application, consistent with electrolytic performance expectations.
• Reliability and temperature — Endurance of 1000 hours at 85°C; operational temperature range from −40°C to +85°C.
• Package and mounting — Snap‑in radial can (φ35 × 25 mm) for secure mechanical retention; supplied in tray packing for handling and assembly.
• Standards compliance — RoHS compliant as indicated in product data.

Typical Applications

• High‑grade audio amplifiers — Bulk energy storage and smoothing in amplifier power sections where audio fidelity and stable supply decoupling are required.
• Audio equipment power modules — Power filtering and reservoir use in dedicated audio electronics designed for high‑fidelity sound reproduction.
• HD audio systems — Integration into audio equipment where low loss (tan δ) and controlled ripple handling support sound quality objectives.

Unique Advantages

• Audio‑oriented design — Part of Nichicon’s LKG series engineered for high‑grade audio equipment, focusing on tone quality and fidelity.
• High ripple handling — 3.0 A low‑frequency ripple current rating at 120 Hz helps maintain stable DC rails under dynamic audio loads.
• Compact, secure mounting — φ35 × 25 mm snap‑in can provides a space‑efficient solution with reliable board retention for power sections.
• Measured low dissipation — tan δ = 0.3 (20°C, 120 Hz) supports low power loss in audio signal environments where dissipation affects performance.
• Engineered reliability — 1000 hours endurance at 85°C and an operational range of −40°C to +85°C provide predictable behavior over typical audio equipment lifecycles.
• RoHS compliant — Meets RoHS directive requirements noted in the product data, supporting regulatory compliance in assemblies.
