LKG1E222MESZCK

The LKG1E222MESZCK from Nichicon is a snap‑in aluminum electrolytic capacitor designed for audio equipment. It combines 2.2 mF capacitance at 25 V with a snap‑in radial can package tailored for high‑fidelity audio applications.

Key value comes from low‑frequency ripple handling, defined dielectric loss and a long endurance rating at elevated temperature, making it suitable for power filtering and decoupling in professional and consumer audio designs.

Key Features

• Electrical — Capacitance & Voltage 2.2 mF (2200 µF) rated at 25 V with ±20% tolerance (measured at 120 Hz, 20 °C).
• Loss Characteristics Tangent of loss angle (tan δ) = 0.22 measured at 20 °C, 120 Hz, providing a specified dielectric loss reference for audio circuits.
• Ripple Handling Low‑frequency ripple current of 1.85 A at 120 Hz for bulk filtering and smoothing in power rails.
• Leakage Current Specified leakage current of 700 µA after application of rated voltage, useful for predictable biasing behavior.
• Reliability & Endurance Rated for 1000 hours at 85 °C with capacitance change within ±20% and leakage current within specified limits after the endurance test.
• Mechanical & Mounting Snap‑in radial can package (φ22 × 35 mm length) for secure panel or chassis mounting; supplied in tray packing.
• Operating Range & Compliance Operating temperature −40 °C to +85 °C and RoHS compliant.
• Audio‑Focused Series Part of Nichicon’s LKG family, developed for high‑grade audio equipment and tone quality; this unit is TYPE‑III (Super Through) grade as indicated by the CK grade code.

Typical Applications

• Professional Audio Power Supplies — Bulk filtering and smoothing on amplifier and preamplifier power rails where low‑frequency ripple handling is required.
• Audio Amplifier Decoupling — Local energy storage and decoupling for high‑current sections of audio amplifiers to support transient demands.
• High‑Fidelity Consumer Audio — Power conditioning in receivers, integrated amplifiers and high‑grade audio equipment where tone quality is a design priority.

Unique Advantages

• Audio‑oriented design: Belongs to Nichicon’s LKG series developed specifically for high‑grade audio equipment, supporting tone quality considerations.
• High ripple capability: 1.85 A ripple current at 120 Hz enables robust smoothing and reduces stress on downstream circuitry.
• Defined dielectric loss: tan δ = 0.22 at standard measurement conditions provides predictable performance for audio signal paths.
• Rated endurance at elevated temperature: 1000 hours at 85 °C gives designers a measurable reliability baseline for thermal stress cases.
• RoHS compliant and tray packed: Environmentally compliant and supplied in tray packing for organized handling in production.
• Snap‑in radial package: Simplifies secure mechanical mounting in chassis or board assemblies requiring a robust can style capacitor.
