LKG1K223MKZS

The LKG1K223MKZS is a high-capacitance aluminum electrolytic capacitor in a lug-terminal (solder lug) radial can package, optimized for audio equipment use. It delivers 22,000 µF at a rated voltage of 80 V with a robust low-frequency ripple current capability and long endurance for demanding power‑supply and energy‑storage roles in high‑grade audio systems.

Key attributes include a high ripple current rating, a wide operating temperature range of −40 °C to 85 °C, RoHS compliance, and mechanical packaging suited to secure lug mounting. The part is currently designated End Of Life.

Key Features

• High Capacitance: 22,000 µF nominal capacitance for bulk energy storage and low-frequency smoothing.
• Rated Voltage: 80 V rating suitable for higher-voltage audio power rails and amplifier supplies.
• High Ripple Current: Low-frequency ripple current of 13.7 A (120 Hz) to handle substantial AC ripple in power-supply applications.
• Endurance / Lifetime: Rated for 1,000 hours at 85 °C with specified limits on capacitance change, tan δ, and leakage current after endurance testing.
• Temperature Range: Operates from −40 °C to +85 °C for use across a broad set of environmental conditions.
• Leakage and Dissipation: Specified leakage current (3,970 µA) and tan δ (0.2 at 20 °C, 120 Hz) for predictable electrical behavior.
• Package and Mounting: Radial can with lug (solder lug) terminals for secure mechanical attachment; size φ76 × 100 mm (D × L) packaged in tray packing.
• Tolerance and Marking: Capacitance tolerance ±20% (120 Hz, 20 °C); marking printed in gold on a black sleeve as specified for the LKG series.
• Regulatory Compliance: RoHS compliant per the series documentation.

Typical Applications

• High‑fidelity Audio Amplifiers: Bulk filtering and energy storage on amplifier power rails to support sustained audio transients.
• Audio Power Supplies: Smoothing and ripple management for power-supply stages in high‑grade audio equipment.
• HD Audio Systems: Large-capacitance reservoir to maintain stable DC rails for high-resolution audio playback systems.

Unique Advantages

• Large Energy Storage: 22,000 µF capacitance provides substantial reservoir capability for low‑frequency and transient demands in audio power systems.
• High Ripple Handling: 13.7 A ripple current rating reduces thermal stress under heavy ripple loads, supporting stable operation in power-supply environments.
• Designed for Audio Use: Part of Nichicon’s LKG series, engineered and specified for high‑grade audio applications and HD audio performance.
• Rugged Temperature Performance: −40 °C to +85 °C operating range and 1,000‑hour endurance at 85 °C support reliability in controlled thermal environments.
• Secure Mechanical Mounting: Lug (solder lug) terminals in a radial can package enable robust attachment in chassis or PCB mounting arrangements.
• Regulatory Compliance: RoHS compliance simplifies environmental and regulatory alignment for product designs.
