LKG1K821MESYCK

The LKG1K821MESYCK is an aluminum electrolytic, snap-in (radial can) capacitor in Nichicon’s LKG series, engineered for audio equipment applications. It provides 820 µF capacitance at an 80 V rating and is optimized for use where stable low-frequency filtering and reliable power handling are required.

As part of the LKG family designed for high-grade audio, this component combines audio-focused design intent with measurable electrical characteristics such as low loss (tan δ), defined leakage, and specified ripple-handling capacity to support amplifier and power-supply circuits in professional and consumer audio systems.

Key Features

• Capacitance & Voltage — 820 µF nominal capacitance with a rated voltage of 80 V and a tolerance of -20% to +20%.
• Audio-focused Series — Part of the LKG series designed for audio equipment and high-fidelity applications.
• Low Loss (tan δ) — Tangent of loss angle (tan δ) specified at 0.2 under measurement conditions of 20°C and 120 Hz at rated voltage.
• Ripple Current Capability — Low-frequency ripple current rating of 2.4 A at 120 Hz, supporting power-supply smoothing in audio circuits.
• Leakage Current — Leakage current specified at 760 µA (after standard application conditions).
• Temperature & Endurance — Operating range from -40°C to +85°C with an endurance rating of 1000 hours at 85°C.
• Stability at Low Temperature — Impedance ratios per series data: Z(-25°C)/Z(+20°C) = 4 and Z(-40°C)/Z(+20°C) = 12 (measurement frequency 120 Hz).
• Mechanical & Packaging — Snap-in radial can package, size φ20 × 50L (diameter × length), supplied in tray packing for assembly handling.
• Regulatory Status — RoHS compliant.

Typical Applications

• High-fidelity audio amplifiers — Bulk and smoothing capacitance for amplifier power supplies where low-frequency ripple handling is required.
• Studio and consumer audio equipment — Energy storage and filtering in power rails for high-grade audio electronics.
• Power supply filtering in audio subsystems — Supports decoupling and smoothing tasks that benefit from the capacitor’s rated ripple current and voltage.

Unique Advantages

• Audio-oriented design: Being part of the LKG series, this capacitor is specified for audio equipment use, aligning component selection with sound-quality-focused designs.
• Measured low loss: A tan δ of 0.2 (20°C, 120 Hz, rated voltage) provides predictable dissipation characteristics for audio power circuits.
• Robust ripple handling: 2.4 A low-frequency ripple current rating at 120 Hz enables effective power-supply filtering in amplifier designs.
• Wide operating range and proven endurance: Specified for -40°C to +85°C operation with 1000 hours endurance at 85°C for demanding thermal environments.
• Compact snap-in form factor: φ20 × 50L radial can with snap-in terminals simplifies installation in chassis-mounted or board-mounted power modules.
• Regulatory compliance: RoHS status ensures alignment with common environmental directives.
