LKG1H182MESACK

The LKG1H182MESACK is an aluminum electrolytic capacitor from Nichicon’s LKG series, featuring a snap-in terminal package tailored for audio equipment. It delivers 1800 µF at 50 V in a compact φ25 × 40 mm can and is designed for applications where audio-grade performance and robust power-handling are required.

Key attributes include a measured tanδ of 0.22 (20°C, 120 Hz), a low-frequency ripple current rating of 2.45 A (120 Hz), and a rated operating temperature range of −40°C to +85°C with a specified endurance of 1000 hours at 85°C.

Key Features

• Capacitance & Rated Voltage — 1.8 mF (1800 µF) nominal capacitance at a rated voltage of 50 V, with a capacitance tolerance of ±20% (120 Hz, 20°C).
• Audio-Grade Design — Part of the LKG series developed for audio equipment; the series emphasizes high-fidelity sound quality and is specified for audio use.
• Snap-in Package — Radial, can-style snap-in mounting for secure board retention in through-hole assemblies; physical size φ25 × 40 mm (D × L), metric dimensions L: 4 cm × D: 2.5 cm.
• Low-Frequency Ripple Handling — Rated low-frequency ripple current of 2.45 A at 120 Hz to support power filtering duties in audio power circuits.
• Loss & Leakage — Specified tangent of loss angle (tanδ) of 0.22 at 20°C/120 Hz and leakage current of 900 µA, enabling predictable performance under rated conditions.
• Temperature & Endurance — Operating range −40°C to +85°C with a lifetime (endurance) rating of 1000 hours at 85°C when operated at rated voltage.
• Compliance & Packaging — RoHS compliant and supplied in tray packing for handling and assembly.

Typical Applications

• High-fidelity audio equipment — Suited for use in audio designs where series-level LKG performance characteristics are specified.
• Audio power supply filtering — Used for bulk smoothing and decoupling in amplifier and preamplifier power stages where rated ripple current and voltage are required.
• Audio system OEM assemblies — Suitable for integration into assembled audio products that expect RoHS-compliant, snap-in electrolytic capacitors in a compact footprint.

Unique Advantages

• Audio-focused engineering — Part of Nichicon’s LKG series designed specifically for audio equipment, supporting high-fidelity applications.
• Measurable low-loss performance — tanδ specified at 0.22 (20°C, 120 Hz) gives designers a clear expectation of dissipation characteristics in audio-frequency conditions.
• Robust ripple capability — 2.45 A ripple current rating at 120 Hz helps sustain power filtering performance in demanding audio power circuits.
• Compact snap-in form factor — φ25 × 40 mm package with snap-in mounting simplifies mechanical retention for through-hole assemblies.
• Documented endurance — Rated for 1000 hours at 85°C under rated voltage, enabling evaluation against life-cycle requirements.
• Regulatory compliance — RoHS compliant for regulated-product bill-of-materials requirements.
