LKG1E472MESZBK

The LKG1E472MESZBK is a snap-in, polarized aluminum electrolytic capacitor with 4700 µF capacitance and a 25 V rated voltage. It is part of Nichicon’s LKG series developed for audio use and is specified for applications that require high capacitance, controlled loss characteristics, and secure snap-in mounting.

Designed for audio equipment and HD audio applications, this capacitor combines a compact radial can package with measurable performance data—tolerance, loss angle, ripple handling and endurance—that engineers can use directly in power filtering and decoupling designs.

Key Features

• Capacitance & Tolerance — 4700 µF (4.7 mF) with a tolerance of ±20% (measured at 120 Hz, 20 °C).
• Rated Voltage — 25 V DC for typical low-voltage audio and power supply stages.
• Low Loss — Tangent of loss angle (tan δ) of 0.3 measured at 20 °C and 120 Hz, indicating controlled dissipation for audio applications.
• Ripple Current Handling — Low-frequency ripple current rating of 2.3 A at 120 Hz for robust bulk and smoothing duties.
• Leakage Current — Specified leakage current of 1020 µA.
• Endurance & Temperature Range — Rated for 1000 hours at 85 °C and an operating temperature range of −40 °C to +85 °C.
• Package & Mounting — Snap-in, radial can (φ22 × 35 mm) designed for secure PCB installation; supplied in tray packing.
• Audio-Focused Series Grade — Part of the LKG series “For Audio Use”; the BK grade corresponds to TYPE-II, the center grade aimed at balanced sound quality using electrode foil.
• RoHS Compliance — Declared RoHS compliant.

Typical Applications

• High-Fidelity Audio Amplifiers — Bulk supply filtering and decoupling where 4700 µF and a 2.3 A ripple current rating support steady rail voltage under dynamic audio loads.
• Audio Power Supplies — Smoothing and energy storage in power modules for audio equipment operating up to 25 V.
• HD Audio Systems — Component selection for equipment targeting high-tone-quality performance as addressed by the LKG series.

Unique Advantages

• Audio-oriented electrochemical design — Series design and TYPE-II (BK) grade focus on balanced sonic performance useful in audio equipment builds.
• Measured electrical characteristics — Explicit values for tan δ, ripple current and leakage current enable predictable circuit design and validation.
• Secure snap-in mounting — Radial snap-in can simplifies board installation and mechanical retention in assemblies.
• Rated endurance at elevated temperature — 1000 hours at 85 °C offers a defined lifecycle metric for thermal-stressed environments.
• RoHS compliant — Aligns with lead-free product requirements for regulated regions.
