LKG1H223MKZS

The LKG1H223MKZS is a lug‑terminal aluminum electrolytic capacitor from Nichicon’s LKG series, engineered for audio equipment. It offers 22 000 µF capacitance at 50 V in a radial can with solder‑lug mounting, providing bulk energy storage and low‑frequency ripple handling for high‑fidelity audio applications.

Designed for use across consumer and professional audio systems, this capacitor balances high capacitance, robust ripple current capability, and a broad operating temperature range to support power supply smoothing and audio amplifier rail stabilization.

Key Features

• High Capacitance — 22 000 µF nominal capacitance (±20%) for substantial bulk energy storage and smoothing in power supply rails.
• 50 V Rated Voltage — Suitable for higher‑voltage audio power supplies and amplifier rail applications requiring a 50 V rating.
• Robust Ripple Handling — Low‑frequency ripple current capability of 10.5 A (120 Hz) to manage large ripple currents encountered in audio power stages.
• Audio‑Focused Design — Part of the LKG series specified “for audio use,” engineered with priority on high‑fidelity sound quality for audio equipment applications.
• Lug/Solder‑Lug Mounting — Radial can with solder lug (lag terminal) mounting for secure mechanical and electrical connections in chassis and PCB assemblies.
• Temperature and Endurance — Rated for −40 °C to +85 °C with an endurance specification of 1000 hours at 85 °C, enabling reliable operation in typical audio environments.
• Leakage and Loss Characteristics — Specified leakage current up to 3 140 µA and tangent of loss angle (tan δ) of 0.22 (measured at 20 °C, 120 Hz), allowing designers to budget for standby losses and AC loss.
• Physical Form Factor — Compact radial can size φ63 × 80 mm (L: 8 cm × D: 6.3 cm) with tray packing for handling and assembly.

Typical Applications

• High‑fidelity Audio Amplifiers — Bulk smoothing and reservoir capacitance on amplifier power rails to support stable, low‑noise power delivery for audio output stages.
• Power Supply Filtering — DC link and filtering in audio power supplies where large capacitance and ripple current capability are required.
• Professional Audio Equipment — Use in mixers, preamps, and studio gear that demand stable bulk storage and attention to audio quality characteristics.

Unique Advantages

• Large Energy Storage: 22 000 µF provides significant capacitance per package, reducing the number of units needed for bulk filtering.
• High Ripple Current Capacity: 10.5 A (120 Hz) rating helps maintain voltage stability under heavy audio load transients.
• Audio‑Oriented Series: Part of Nichicon’s LKG line, explicitly specified for audio use and designed with fidelity considerations in mind.
• Durable Operating Range: −40 °C to +85 °C operating window with 1000 h endurance at 85 °C supports reliable long‑term performance in typical audio installations.
• Secure Mechanical Mounting: Lug terminal (solder lug) package ensures robust electrical connections in chassis‑mounted or PCB‑anchored installations.
