LKG1K222MESBAK

The LKG1K222MESBAK is an aluminum electrolytic, snap-in terminal capacitor engineered for audio equipment. It delivers 2.2 mF (2200 µF) of bulk capacitance at an 80 V rated voltage in a radial, snap-in can package designed for board-level installation.

Targeted at high-grade audio applications, this part combines audio-focused design with practical power-handling and thermal endurance: a 2.55 A ripple current rating (120 Hz), a specified leakage current rating, and a 1000-hour endurance at 85°C to support stable operation in demanding audio power supplies and amplifier circuits.

Key Features

• Capacitance & Voltage — 2.2 mF (2200 µF) nominal capacitance with an 80 V rated voltage and ±20% tolerance for bulk energy storage and smoothing in higher-voltage audio circuits.
• Audio-Focused Design — Part of the LKG series designed specifically for audio equipment, prioritizing high-fidelity sound quality in high-grade and HD audio systems.
• Low Loss Performance — Tangent of loss angle (tan δ) specified at 0.25 (measurement conditions per series datasheet: 120 Hz, 20°C), supporting stable AC behavior in audio-frequency applications.
• Ripple Current Handling — Rated ripple current of 2.55 A at 120 Hz, enabling effective smoothing under dynamic load conditions common in amplifier and power-supply stages.
• Leakage & Endurance — Specified leakage current of 1,250 µA and rated endurance of 1000 hours at 85°C; series endurance criteria specify capacitance change within ±20%, tan δ ≤ 200% of initial, and leakage not exceeding initial specified value after test.
• Package & Mounting — Snap-in radial can (φ30 × 30 mm) for secure board mounting and straightforward integration into PCB layouts; polarized construction intended for correct-power polarity applications.
• Environmental Compliance — RoHS compliant per manufacturer information.

Typical Applications

• High-Grade Audio Amplifiers — Bulk energy storage and smoothing for power rails in professional and consumer amplifiers where stable supply under dynamic loads is required.
• Audio Power Supplies — Filtering and decoupling in high-voltage audio power supplies, leveraging the 80 V rating and 2.55 A ripple capability.
• HD Audio Systems — Designed for audio equipment that prioritizes fidelity; suitable for use where series-level audio-grade components are specified.
• Signal Conditioning Modules — Bulk capacitance for reservoir or reservoir-decoupling roles in audio front-end and processing modules.

Unique Advantages

• Audio-First Engineering: Built as part of the LKG series expressly for audio use, offering component-level choice aligned to high-fidelity system goals.
• High Voltage Capability: The 80 V rating enables use in higher-voltage audio and power designs where lower-voltage electrolytics would be unsuitable.
• Robust Ripple Handling: 2.55 A ripple current rating at 120 Hz supports sustained smoothing under dynamic amplifier loads, improving supply stability.
• Proven Endurance: 1000 hours at 85°C endurance with defined post-test limits provides quantifiable performance expectations for thermal stress and long-term use.
• Practical Snap-In Form Factor: φ30 × 30 mm radial snap-in can simplifies PCB mounting and replacement in rack or chassis-mounted audio equipment.
• Regulatory Compliance: RoHS compliance addresses environmental regulatory requirements for assembly and product shipments.
