LKG1J223MKNF

The LKG1J223MKNF from Nichicon is a lug-terminal aluminum electrolytic capacitor in the LKG series, optimized for audio equipment. It delivers high bulk capacitance (22,000 µF) at a 63 V rating in a radial can with solder lug mounting, making it suitable for high-capacitance power supply and filtering roles in audio designs.

Designed for high-grade audio applications, the LKG1J223MKNF combines large energy storage, a low-frequency ripple current capability, and a wide operating temperature range to support stable performance in demanding audio power stages.

Key Features

• High Capacitance — 22,000 µF (22 mF) provides substantial bulk energy storage for smoothing and reservoir applications in power supplies.
• 63 V Rated Voltage — Suitable for audio amplifier rails and other mid-voltage power systems requiring robust DC link capacitance.
• Lug-terminal, Radial Can Package — Solder lug (lag) mounting and a φ40 × 100 mm can (radial, solder lug) facilitate secure mechanical and electrical connections in chassis-mounted or point-to-point layouts.
• Ripple Current Capability — Low-frequency ripple current rating of 6.6 A at 120 Hz supports sustained ripple handling in audio power supply environments.
• Endurance and Temperature Range — Rated for 1,000 hours at 85°C and specified operating range of −40°C to +85°C for reliable performance under elevated ambient conditions.
• Electrical Characteristics — Capacitance tolerance −20% to +20% and specified tan δ (loss tangent) of 0.3 at 20°C, 120 Hz; leakage current specified at 3,530 µA.
• RoHS Compliant — Meets RoHS requirements as specified for the series.

Typical Applications

• High-Fidelity Audio Amplifiers — Bulk smoothing and reservoir capacitance for power amplifier rails where large stored energy and stable ripple handling improve supply stability.
• Professional Audio Power Supplies — Filtering and decoupling in high-current low-frequency stages of audio power supplies that require substantial capacitance at mid-range voltages.
• Studio and Broadcast Equipment — Energy storage and ripple suppression for equipment that prioritizes low-noise power delivery and consistent performance across temperature extremes.

Unique Advantages

• Large Energy Storage: 22,000 µF at 63 V provides significant reservoir capacity to maintain rail stability and reduce voltage sag under dynamic audio loads.
• Robust Ripple Handling: 6.6 A ripple current (120 Hz) supports sustained AC loading typical of transformer-rectified audio power supplies.
• Audio-Focused Design: Series design emphasis for high-grade audio equipment supports use in systems where sound fidelity is a priority.
• Wide Operating Temperature: −40°C to +85°C operation and 1,000-hour endurance at 85°C promote reliable long-term performance in varied environments.
• Secure Mechanical Mounting: Lug-terminal solder-lug configuration and radial can package provide durable mounting and straightforward integration into chassis-level assemblies.
• Regulatory Compliance: RoHS compliance reduces end-product regulatory risk for electronic equipment manufacturers.
