LKG1K122MESBAK

The LKG1K122MESBAK is a snap-in, radial aluminum electrolytic capacitor in Nichicon's LKG series, specified for audio equipment and high-fidelity applications. It provides 1.2 mF (1200 µF) capacitance at an 80 V rating in a compact φ30 × 20 mm can with snap-in mounting and tray packing.

Designed with audio performance in mind, the LKG series emphasizes sound quality while offering practical power-handling and reliability characteristics for professional and high-grade audio designs. Key electrical parameters include a low-frequency ripple current rating of 2.0 A (120 Hz), a dissipation factor (tanδ) of 0.25 (20°C, 120 Hz), and a rated operating range of −40°C to +85°C with 1000 hours endurance at 85°C.

Key Features

• Form Factor — Snap-In Radial Can Snap-in mounting and radial can package with dimensions φ30 × 20 mm and tray packing for board-level power modules.
• Capacitance & Voltage 1.2 mF (1200 µF) nominal capacitance with ±20% tolerance at 120 Hz, rated for 80 V operation.
• Audio-Grade Series Part of Nichicon's LKG series, developed for audio equipment and high-fidelity sound quality.
• Ripple Current Capability Low-frequency ripple current rating of 2.0 A at 120 Hz to support power smoothing in audio power supplies.
• Dissipation & Leakage tanδ = 0.25 (measured at 20°C, 120 Hz) and specified leakage current of 920 µA for predictable analog behavior.
• Temperature & Endurance Operating temperature −40°C to +85°C with a rated lifetime of 1000 hours at 85°C under specified conditions.
• Regulatory RoHS compliant.

Typical Applications

• High-fidelity audio amplifiers — Power smoothing and decoupling where stable capacitance and ripple handling support audio performance.
• Professional audio equipment — Designed for use in high-grade audio products where tone quality is a priority.
• Audio power supplies and filtering — Bulk filtering and low-frequency decoupling on higher-voltage audio rails.

Unique Advantages

• Audio-focused design: Series-level development targets high tone quality and high-fidelity applications, aligning the part with professional audio needs.
• High voltage in a compact can: 80 V rating combined with 1200 µF capacitance in a φ30 × 20 mm package reduces board footprint for higher-voltage audio rails.
