LKG1H472MESBBK

The LKG1H472MESBBK is an aluminum electrolytic capacitor in a snap-in radial can package, optimized for audio equipment. It provides 4.7 mF (4700 µF) capacitance at a 50 V rating with a ±20% tolerance, and is designed for applications that require capacitance stability, ripple handling, and reliable operation across a wide temperature range.

Part of Nichicon’s LKG series for audio use, this snap-in terminal capacitor combines a compact φ30 × 40 mm package with a 3.3 A ripple current rating (120 Hz) and a specified endurance of 1000 hours at 85°C, making it suitable for power supply smoothing and reservoir duties in audio systems.

Key Features

• Capacitance & Voltage — 4.7 mF (4700 µF) rated at 50 V with ±20% tolerance for bulk energy storage and filtering in power rails.
• Mounting & Package — Snap-in terminal, radial can (φ30 × 40 mm) for secure chassis or board installation in compact audio assemblies.
• Ripple Handling — 3.3 A ripple current rating at 120 Hz to support smoothing of audio power supplies and reduce output ripple under load.
• Loss Characteristic (tan δ) — Specified tan δ of 0.3 (measurement at 120 Hz, 20°C) for predictable AC loss behavior in audio circuits.
• Leakage Current — Initial leakage current specified at 1450 µA to inform bias and bleed resistor design.
• Temperature & Endurance — Operating range −40°C to +85°C with a rated life of 1000 hours at 85°C under rated voltage conditions.
• Regulatory — RoHS compliant.

Typical Applications

• Audio Power Supplies — Used as bulk smoothing and reservoir capacitance to stabilize DC rails for amplifiers and reduce audible ripple.
• High-Fidelity Amplifiers — Provides energy storage and decoupling in preamp and power amp sections where consistent capacitance and low loss are required.
• Audio System Filtering — Employed in output and supply filter networks to improve transient response and maintain stable biasing.

Unique Advantages
