The LKG1H392MESAAK is an aluminum electrolytic, snap-in terminal capacitor from Nichicon's LKG series, optimized for audio equipment applications. It delivers high bulk capacitance and a voltage rating suited to power supply filtering and decoupling in high-fidelity audio designs.

Key attributes include a 3.9 mF nominal capacitance, 50 V rated voltage, snap-in radial can package for robust mounting, and construction targeted at audio use. Note: this part is listed as End of Life/Discontinued.

Key Features

• Capacitance and Voltage — 3.9 mF (3900 µF) nominal capacitance with a 50 V rated voltage and ±20% tolerance for bulk energy storage and smoothing in audio power rails.
• Audio-focused Grade — Part of the LKG series designed for audio equipment; series documentation identifies versions intended to prioritize high-fidelity sound quality.
• Package and Mounting — Snap-in radial can (snap-in terminal) package for secure board mounting and ease of installation in chassis or PCB power trays.
• Dissipation Characteristic — Specified tangent of loss angle (tan δ = 0.3) measured at 120 Hz, 20°C, providing a defined dissipation parameter for system design.
• Temperature and Endurance — Rated operating range of −40°C to +85°C with an endurance specification of 1000 hours at 85°C under rated voltage.
• Ripple Capability — Rated ripple current of 2.5 A at 120 Hz, suitable for smoothing and ripple suppression in audio power supplies.
• Polarized Electrolytic — Polarized design for DC power rail applications; packaged in a black sleeve with gold-color marking as per series marking practice.
• RoHS Compliant — Conforms to RoHS directives as indicated for the LKG series.
• Compact Footprint — Physical size approximately 25 × 30 mm (L: 3 cm × D: 2.5 cm), balancing capacitance with a small board footprint.

Typical Applications

• High-Fidelity Audio Amplifiers — Bulk filtering and reservoir capacitance on amplifier power rails to support stable, low-noise operation.
• Professional Audio Equipment — Power smoothing in mixers, preamps, and studio gear where audio-focused component selection matters.
• Consumer Hi‑Fi Systems — Energy storage and ripple reduction in power supplies used by home audio receivers and integrated amplifiers.

Unique Advantages

• Audio-Oriented Design: Series-level design emphasis on high-grade audio use supports fidelity-focused system designs.
• High Bulk Capacitance: 3.9 mF nominal value provides substantial energy storage for power-supply smoothing in compact form.
• Robust Snap-In Mounting: Snap-in radial can simplifies secure installation for chassis- and board-mounted power components.
• Defined Dissipation Parameter: Specified tan δ (0.3 at 120 Hz, 20°C) gives engineers a measurable loss characteristic for thermal and damping calculations.
• Endurance Specified: 1000 hours at 85°C under rated voltage provides a clear reliability expectation for thermal stress conditions.
• Regulatory Compliance: RoHS compliance supports designs that must meet environmental substance restrictions.

Why Choose LKG1H392MESAAK?

The LKG1H392MESAAK is positioned for audio-focused power-supply roles where a combination of high capacitance, a 50 V rating, and snap-in mechanical retention are needed. Its specified electrical characteristics—capacitance, tan δ, ripple current, and endurance—allow engineers to design predictable filter and reservoir stages for audio amplifiers and professional equipment.

This part is suitable for designers and procurement teams specifying components for high-fidelity audio products that require clear, measurable capacitor performance and RoHS compliance. Because the part is End of Life/Discontinued, verify current availability and consider series alternatives if long-term sourcing is required.
