LGG2W471MELC40

The LGG2W471MELC40 is an aluminum electrolytic capacitor in a snap-in terminal, radial can package offering 470 µF capacitance at a 450 V rated voltage. It is part of Nichicon's LGG series and is intended for general-purpose applications that require high-voltage bulk capacitance in a compact footprint.

Designed for sustained operation up to 105°C, this device delivers low loss (tanδ 0.2 at 20°C/120Hz), defined leakage current, and rated ripple performance at both low and high frequencies, making it suitable where stable high-voltage energy storage and ripple handling are required.

Key Features

• Rated Capacitance & Voltage — 470 µF nominal capacitance with a 450 V rated voltage and ±20% tolerance, providing high-voltage bulk storage in a single component.
• Snap-In Radial Can Package — Snap-in terminal type in a radial, can-style package (φ35 × 40 mm) for secure PCB mounting and straightforward assembly; tray packing for mass production.
• Loss and Leakage Characteristics — Tangent of loss angle (tanδ) 0.2 max at 20°C and 120 Hz (450 V); leakage current specified at 1370 µA.
• Ripple Current Handling — Rated ripple current of 1.55 A at 120 Hz (low frequency) and 2.216 A at 100 kHz (high frequency) to support both mains-frequency and high-frequency ripple conditions.
• Wide Operating Temperature — Specified for operation from −25°C to +105°C, with endurance of 2000 hours at 105°C under rated conditions.
• RoHS Compliant — Compliant to RoHS directives, meeting applicable environmental regulations.

Typical Applications

• General Purpose Electronics — Provides high-voltage bulk capacitance for general-purpose designs that require 470 µF at 450 V.
• Power Filtering — Handles low- and high-frequency ripple currents (1.55 A @120 Hz, 2.216 A @100 kHz) for smoothing and filtering in high-voltage circuits.
• Energy Storage in High-Voltage Modules — Offers compact high-voltage storage in a snap-in radial can suitable for production assemblies.

Unique Advantages

• High-voltage bulk capacitance: 470 µF at 450 V provides substantial energy storage in a single component for high-voltage designs.
• Dual-frequency ripple capability: Specified ripple current at both 120 Hz and 100 kHz supports applications with mixed-frequency ripple profiles.
• Endurance at elevated temperature: Rated 2000 hours at 105°C, enabling sustained operation under high-temperature stress when subjected to rated ripple and DC bias.
• Controlled loss and leakage: tanδ 0.2 (20°C/120Hz) and defined leakage current (1370 µA) allow predictable behavior for filter and storage applications.
• Compact snap-in form factor: φ35 × 40 mm snap-in can and tray packing streamline PCB mounting and volume production workflows.
• Series heritage: LGG series design reduces case size compared with certain prior LG series variants, aiding equipment downsizing efforts.
