LKG1H223MKNF

The LKG1H223MKNF is an aluminum electrolytic capacitor in a lug (solder-lug) radial can package, specified at 22,000 µF and 50 V. It is part of Nichicon’s LKG series developed for audio applications and designed with audio-grade priorities in mind.

This unit is built for power filtering and energy storage in audio equipment, offering a rated capacitance of 22 mF, a rated voltage of 50 V, and endurance specified for 1,000 hours at 85 °C. Status: End Of Life.

Key Features

• Capacitance & Voltage — 22,000 µF nominal capacitance at a rated voltage of 50 V with a tolerance of ±20% (measured at 120 Hz, 20 °C).
• Audio-oriented design — Part of the LKG series marketed for high-grade audio equipment and engineered to prioritize high-fidelity sound quality.
• Low-frequency ripple handling — Rated low-frequency ripple current of 5.4 A at 120 Hz, suitable for reservoir and smoothing roles in audio power supplies.
• Electrical loss and leakage — Specified tangent of loss angle (tan δ) of 0.3 (20 °C, 120 Hz); leakage current listed as 3,140 µA.
• Endurance and temperature range — Endurance rated 1,000 hours at 85 °C; operating temperature range −40 °C to +85 °C.
• Mechanical and mounting — Lug / solder-lug (lag terminal) radial can package; physical size φ40 × 68 mm (6.8 × 4.0 cm); supplied in tray packing.
• Environmental compliance — RoHS compliant.

Typical Applications

• High-fidelity audio amplifiers — Bulk reservoir and power supply smoothing where large capacitance (22,000 µF) and 50 V rating are required for stable rail performance.
• Studio and pro-audio equipment — Energy storage and decoupling in audio systems that emphasize tonal quality and low-frequency performance.
• Power filtering for audio electronics — Low-frequency ripple current capability (5.4 A at 120 Hz) supports smoothing under moderate load conditions.

Unique Advantages

• Large energy storage: 22,000 µF nominal capacitance provides significant reservoir capacity for audio power supplies and smoothing.
• Audio-grade series pedigree: LKG series is specified for high-grade audio use, aligning component selection with sonic priorities in design.
• High ripple tolerance: 5.4 A low-frequency ripple current rating (120 Hz) helps maintain performance under ripple-heavy supply conditions.
• Specified endurance: Rated for 1,000 hours at 85 °C, enabling designers to account for long-term performance in elevated-temperature environments.
• Robust mechanical form factor: Lug/solder-lug radial can package and tray packing support secure mounting and repeatable assembly for through-hole designs.
• Regulatory compliance: RoHS compliant for restricted substances requirements.
