LKG2A222MESCBK

The LKG2A222MESCBK is a snap‑in aluminum electrolytic capacitor from Nichicon’s LKG series, engineered for audio equipment applications. It pairs a high capacitance of 2200 µF with a 100 V rating to support energy storage and smoothing in audio power chains.

Designed as a radial can with snap‑in mounting, this component is optimized for high‑grade audio systems where low‑frequency ripple handling and stable performance across a wide temperature range are required. The part is RoHS compliant and follows the LKG series’ audio‑focused design approach.

Key Features

• Capacitance: 2200 µF (2.2 mF) with tolerance ±20% at 120 Hz, 20°C, providing substantial bulk storage for power supply smoothing.
• Rated Voltage: 100 V — suitable for higher‑voltage audio power stages and rail filtering.
• Low‑frequency ripple handling: 3.8 A ripple current specified at 120 Hz, supporting robust performance under AC ripple conditions typical in audio power supplies.
• Loss characteristics: tanδ = 0.25 (measured at 20°C, 120 Hz), enabling predictable dissipation behavior within audio circuits.
• Leakage current: 1400 µA (specified condition), providing a defined baseline for power loss and bias considerations.
• Temperature and endurance: Operating range −40°C to +85°C with endurance rated at 1000 hours at 85°C under rated voltage.
• Package and mounting: Radial, can‑type with snap‑in terminal for secure chassis/board mounting; physical size φ35 × 40 mm length supports compact power assemblies.
• Audio‑oriented series design: Part of Nichicon’s LKG family, developed for audio equipment and graded as TYPE‑II (Gold Tune) in the LKG series.
• Regulatory: RoHS compliant.

Typical Applications

• Professional audio power supplies: Bulk filtering and smoothing for amplifier power rails where 100 V rating and high capacitance are required.
• High‑fidelity amplifiers: Decoupling and energy buffering to support transient current demands and maintain stable rail voltages.
• Studio and consumer audio equipment: General DC link and reservoir capacitor use in systems designed for high tone quality.

Unique Advantages

• High voltage capability: 100 V rating allows use in higher‑voltage audio power architectures without compromising capacitance.
• Substantial energy storage: 2200 µF provides meaningful bulk capacitance for smoothing and transient support, reducing ripple on supply rails.
• Designed for ripple load: 3.8 A ripple current at 120 Hz helps maintain performance under AC loading typical of audio power supplies.
• Temperature and life characterization: Specified operating range of −40°C to +85°C and 1000 h endurance at 85°C give predictable lifetime behavior under rated conditions.
• Secure snap‑in mounting: Radial snap‑in can facilitates robust mechanical retention for chassis or board assemblies.
• Audio‑focused grade: Inclusion in the LKG series (TYPE‑II) aligns the component with Nichicon’s audio‑oriented design and marking conventions.
