LKG1V222MESZAK

The LKG1V222MESZAK is a snap-in aluminum electrolytic capacitor from Nichicon’s LKG series, engineered for use in audio equipment and high-fidelity applications. It provides 2.2 mF (2200 µF) capacitance at a 35 V rating in a compact φ22 × 20 mm can with snap-in mounting.

Designed to support audio power systems, the part combines bulk capacitance with a 1.45 A low-frequency ripple capability and controlled loss characteristics (tanδ = 0.3 at 20°C, 120 Hz), while meeting RoHS requirements.

Key Features

• Capacitance & Voltage — 2200 µF (2.2 mF) rated at 35 V provides bulk energy storage for power supply smoothing and decoupling in audio circuits.
• Audio-focused performance — Part of the LKG series specified "For Audio Use" and intended for high-grade/HD audio equipment.
• Loss and measurement — Tangent of loss angle (tanδ) specified as 0.3 when measured at 20°C and 120 Hz, enabling predictable AC behavior in audio-frequency applications.
• Low-frequency ripple capability — 1.45 A ripple current rating at 120 Hz for improved stability under power-supply ripple conditions common in audio amplifiers.
• Leakage current — Measured leakage current of 830 µA, useful for designing bias and standby circuits.
• Endurance — Rated life of 1000 hours at 85°C with the specified voltage applied, with endurance criteria defined in the LKG series data.
• Operating temperature — Specified range −40°C to +85°C to accommodate typical professional and consumer audio environments.
• Package & mounting — Radial, can-type snap-in package (φ22 × 20 mm) with tray packing for board-level installation and secure mechanical retention.
• Regulatory status — RoHS compliant as noted for the LKG series.

Typical Applications

• Audio power supply filtering — Bulk smoothing and decoupling in power rails for amplifiers and preamplifiers where 2.2 mF at 35 V is required.
• Professional and consumer HD audio equipment — Energy storage and ripple handling in systems specified for high-fidelity sound reproduction.
• Amplifier output and bias stabilization — Support for low-frequency ripple currents and leakage characteristics relevant to audio bias networks and power stages.

Unique Advantages

• Audio-oriented design — LKG series specification “For Audio Use” aligns the component with high-fidelity audio requirements.
• Compact, snap-in form factor — φ22 × 20 mm can with snap-in terminals simplifies PCB placement and delivers a secure mechanical connection for board-mounted power sections.
• Measured AC performance — Specified tanδ at 20°C/120 Hz and a defined low-frequency ripple rating provide predictable behavior for audio-frequency filter design.
• Defined endurance — 1000-hour life at 85°C under rated voltage provides a clear reliability baseline for thermal-stressed audio electronics.
• Regulatory compliance — RoHS compliance supports use in designs targeting restricted-substance requirements.
