LKG1H223MKZ

The LKG1H223MKZ is a high-capacitance aluminum electrolytic capacitor engineered for audio equipment applications. It uses a lag terminal (solder lug) radial can package and provides 22,000 µF at 50 V with a ±20% tolerance, aimed at reservoir and filtering roles in high-fidelity audio power supplies.

Key electrical characteristics include a low-frequency ripple current rating of 8.3 A (120 Hz), a specified tanδ of 0.3 (measured at 20°C, 120 Hz), and a rated operating temperature range of -40°C to 85°C with a 1,000-hour endurance at 85°C. The part is RoHS compliant and supplied in tray packing.

Key Features

• High Capacitance: 22,000 µF (22 mF) nominal capacitance suitable for bulk energy storage in audio power stages.
• Rated Voltage: 50 V rating for mid-voltage audio and power supply applications.
• Lag Terminal / Radial Can Package: Lag terminal (solder lug) mounting in a radial, can-style package for secure mechanical and electrical connections.
• Ripple Current Capability: Low-frequency ripple current 8.3 A at 120 Hz to support smoothing and decoupling under AC load conditions.
• Loss and Leakage: tanδ (DF) of 0.3 at 20°C, 120 Hz and a specified leakage current of 3,140 µA for predictable loss and standby behavior.
• Temperature and Endurance: Operating range -40°C to 85°C with lifecycle endurance of 1,000 hours at 85°C, meeting defined stability requirements after endurance testing.
• Audio-Grade Design: Designed for high-grade audio equipment and HD audio needs as part of the LKG series.
• Packaging and Compliance: Tray packing for handling and RoHS compliance for environmental requirements.
• Physical Size: Diameter φ50 × length 80 mm (approx. L: 8 cm × D: 5 cm) for layout planning and enclosure fit.

Typical Applications

• High-Fidelity Audio Amplifiers: Bulk energy storage and power-supply smoothing for amplifier stages in high-grade audio equipment.
• Audio Power Supplies: Main reservoir and decoupling capacitor to support stable DC rails under dynamic audio loads.
• Audio Signal Systems: Power conditioning in HD audio systems where sustained ripple current handling and large capacitance are required.

Unique Advantages

• Large Energy Storage: 22,000 µF capacitance provides substantial reservoir capacity for audio power rails, reducing voltage sag under load.
• High Ripple Handling: 8.3 A ripple current rating at 120 Hz supports demanding low-frequency smoothing tasks common in audio power supplies.
• Audio-Focused Specification: Part of the LKG series tailored for high-grade audio equipment and HD audio requirements.
• Durability at Elevated Temperature: 1,000-hour endurance at 85°C delivers predictable performance over specified life testing conditions.
• Practical Mounting and Handling: Lag terminal (solder lug) radial can package simplifies secure solder connections and mechanical mounting in chassis or PCB layouts.
• Regulatory Compliance: RoHS compliant to meet environmental directive requirements.
