LKG1K223MKZ

The LKG1K223MKZ is a high‑capacitance lug‑terminal aluminum electrolytic capacitor from Nichicon's LKG series, engineered for audio applications. Its 22,000 µF capacitance at an 80 V rating and lug (solder‑lug/radial) package make it suitable where substantial energy storage and robust mechanical mounting are required.

Designed with audio use in mind, the LKG series prioritizes sound quality and stable performance across a wide temperature range while meeting RoHS requirements.

Key Features

• High Capacitance & Voltage 22,000 µF capacitance rated at 80 V provides large bulk energy storage for demanding audio circuits.
• Low‑Frequency Ripple Handling Rated low‑frequency ripple current of 11.6 A (120 Hz) supports sustained ripple currents typical in power rails for audio equipment.
• Electrical Characteristics Capacitance tolerance ±20% and specified tanδ (DF) of 0.25 measured at 20°C, 120 Hz for predictable AC performance.
• Leakage & Endurance Specified leakage current of 3970 µA and an endurance rating of 1000 hours at 85°C reflect predictable long‑term behavior under rated conditions.
• Wide Operating Temperature Rated for −40°C to +85°C to maintain performance across common environmental conditions for audio equipment.
• Rugged Package Radial can with solder lug (lug terminal) mounting in a φ63 × 100 mm can offers robust mechanical attachment; supplied in tray packing.
• Regulatory RoHS compliant.

Typical Applications

• High‑grade audio equipment — Suited for use where audio fidelity is prioritized, matching the LKG series design intent for sound quality.
• HD audio systems and amplifiers — Provides bulk energy storage and ripple handling for amplifier power rails and audio power supplies.
• Power reservoir and decoupling in audio circuits — Large capacitance supports stable DC rails and transient response in amplifier designs.

Unique Advantages

• Substantial energy storage: 22,000 µF at 80 V delivers significant bulk capacitance for demanding audio power rails.
• High ripple capability: 11.6 A low‑frequency ripple rating (120 Hz) helps manage sustained ripple currents in power supply applications.
• Designed for audio quality: Part of the LKG series, expressly developed for audio use and high‑fidelity requirements.
• Durable thermal performance: Specified endurance of 1000 hours at 85°C and an operating range of −40°C to +85°C support reliable operation in varied environments.
• Robust mechanical mounting: Lug (solder lug/radial can) package affords secure attachment for heavier can‑style capacitors.
• RoHS compliant: Meets environmental regulatory requirements for lead‑free assemblies.
