LKG1E222MESBCK

The LKG1E222MESBCK is an aluminum electrolytic capacitor in a snap-in terminal radial can designed for audio equipment. It combines a 2.2 mF (2200 µF) rated capacitance with a 25 V rating and an audio-focused construction from Nichicon's LKG series.

Engineered for high-fidelity audio applications, this capacitor offers low loss (tan δ 0.22 at 120 Hz), robust ripple handling, and a compact φ30 × 25 mm can for use where reliable bulk filtering and signal decoupling are required across -40°C to +85°C.

Key Features

• Capacitance and Tolerance — 2.2 mF (2200 µF) with ±20% tolerance (measured at 120 Hz, 20°C), suitable for bulk energy storage and smoothing in audio power stages.
• Rated Voltage — 25 V DC rating provides headroom for a variety of low-voltage audio power supply designs.
• Low Loss — tan δ of 0.22 (specified at 120 Hz) to support low dissipation in audio signal and power circuits.
• Ripple Current Handling — 1.8 A at 120 Hz, enabling effective filtering of low-frequency ripple in power supply rails.
• Leakage Current — Specified leakage current around 700 µA, supporting predictable bias behavior in audio circuits.
• Operating and Endurance — Rated for -40°C to +85°C operation with 1000 hours endurance at 85°C under rated voltage.
• Package and Mounting — Radial, snap-in can (φ30 × 25 mm length) for secure board mounting and mechanical retention in chassis or filter assemblies.
• Audio-Oriented Design — Part of Nichicon's LKG series developed for audio equipment, with sleeve marking printed in gold on black for clear identification.
• RoHS Compliance — Conforms to RoHS directive requirements.

Typical Applications

• High-Fidelity Audio Amplifiers — Bulk decoupling and power-supply smoothing to support low-noise, stable rails for preamplifiers and power amplifiers.
• Audio Power Supplies — Filtering of low-frequency ripple and energy storage in regulated and unregulated audio PSU designs.
• DAC and Analog Front-Ends — Local reservoir and supply stabilization where controlled leakage and low loss contribute to signal integrity.
• Speaker Crossover and Passive Networks — DC blocking and smoothing tasks where a durable snap-in can provides mechanical stability in assemblies.

Unique Advantages

• Audio-focused construction — Designed within the LKG series to prioritize sound quality for HD audio equipment, aligning component behavior with audio system requirements.
• Predictable electrical behavior — Specified tan δ, leakage, and ripple current figures enable engineers to model performance precisely in power and signal paths.
• Robust operating window — Wide -40°C to +85°C range and 1000-hour endurance at 85°C provide reliable service in typical audio environments.
• Secure snap-in mounting — Radial snap-in can package simplifies assembly and provides mechanical retention for chassis-mounted filter banks and power modules.
• Clear identification — Gold-on-black sleeve marking improves traceability and assembly verification in production environments.
• Regulatory compliance — RoHS-compliant materials support environmental and regulatory requirements.
