LKG2A222MESCCK

The LKG2A222MESCCK is an aluminum electrolytic, snap‑in terminal capacitor from Nichicon's LKG series, designed for audio equipment and high‑fidelity applications. It delivers 2200 µF capacitance at a 100 V rating in a φ35 × 50 mm can, combining audio‑oriented series construction with a snap‑in package for secure board mounting.

Engineered for audio use, this TYPE‑III (Super Through) grade part emphasizes tone quality and robust power handling, with datasheet‑specified endurance and performance parameters suitable for demanding audio power supply filtering and bulk energy storage.

Key Features

• Capacitance & Voltage — 2.2 mF (2200 µF) rated at 100 V for bulk energy storage and smoothing in power stages.
• Audio‑Oriented Grade — LKG series, TYPE‑III (Super Through) grade intended for audio equipment; series documentation highlights design focus on high tone quality.
• Low Loss (tan δ) — Specified tan δ of 0.2 (measurement frequency: 120 Hz at 20°C per series datasheet), supporting stable AC characteristics in audio circuits.
• High Ripple Current Capability — 4.75 A ripple current rating at 120 Hz, enabling effective smoothing in high‑current audio power supplies.
• Leakage Current — Specified leakage current of 1400 µA, in line with series performance expectations for large‑value electrolytics.
• Temperature & Endurance — Operating range −40°C to +85°C with an endurance rating of 1000 hours at 85°C as defined by the series specifications.
• Package & Mounting — Snap‑in radial can (φ35 × 50 mm, tray packed) for secure chassis or PCB assembly and simplified handling in production.
• Compliance & Marking — RoHS‑compliant; series marking uses gold color printing on a black sleeve per datasheet guidance.

Typical Applications

• High‑fidelity amplifier power supplies — Bulk smoothing and energy reservoir for clean supply rails in audio amplifiers.
• Audio equipment power filtering — Decoupling and ripple reduction in mixers, preamps, and consumer/pro‑audio electronics.
• Power stage support — Local energy storage for discrete power modules and supply sections in audio systems.

Unique Advantages

• High voltage headroom: 100 V rating provides margin for higher‑voltage audio power rails and robust design options.
• Audio‑focused construction: LKG series TYPE‑III grading targets tonal quality, supporting designers focused on sound performance.
• Strong ripple handling: 4.75 A ripple current (120 Hz) helps maintain low ripple under heavy audio power demands.
• Temperature and endurance specification: −40°C to +85°C operating range with 1000 h endurance at 85°C for predictable lifetime behavior under rated conditions.
• Secure snap‑in mounting: Radial snap‑in can simplifies mechanical retention and assembly in power supply layouts.
• RoHS compliance: Environmentally compliant construction suitable for regulated markets.
