LGW2D471MELA25

The LGW2D471MELA25 is a Nichicon LGW-series aluminum electrolytic capacitor in a snap-in radial can. It provides 470 µF capacitance at a 200 V rating with polarized terminals and is intended for general-purpose applications.

Designed for high ripple-current operation and extended high-temperature endurance, this part supports sustained ripple current at elevated temperatures and is compliant with RoHS (2011/65/EU, (EU)2015/863).

Key Features

• Electrical Capacity — 470 µF capacitance with a rated voltage of 200 V and capacitance tolerance of ±20% (120 Hz, 20°C).
• High Ripple-Current Capability — Rated ripple current of 2.17 A at 120 Hz and 3.255 A at 50 kHz. Frequency coefficient for the 200–250 V range increases ripple allowance at higher frequencies (e.g., 1.50 at 50 kHz).
• High-Temperature Endurance — Specified to withstand 3000 hours of rated ripple current at 105°C with limits on capacitance change, tan δ, and leakage current defined by the endurance spec.
• Operating Temperature Range — –40°C to +105°C (applicable for the 200–250 V range), with documented low-temperature impedance ratios (Z(–25°C)/Z(+20°C) = 3; Z(–40°C)/Z(+20°C) = 12 for 200–250 V).
• Leakage and Loss Characteristics — Leakage current specified by I ≤ 3√(C·V) μA (after 5 minutes at 20°C). Tangent of loss angle (tan δ) maximum 0.15 for the 200–400 V range (measured at 120 Hz, 20°C).
• Mechanical & Mounting — Snap-in terminal, radial can package with size φ25 × 25 mm (diameter × length) for secure board mounting.
• Regulatory Compliance — Compliant to the RoHS directive (2011/65/EU,(EU)2015/863).

Typical Applications

• General-purpose electronic equipment — For designs requiring 200 V, 470 µF bulk capacitance with elevated ripple-current handling and long high-temperature endurance.
• High-ripple circuits — Suitable where sustained rated ripple current at up to 105°C is required, supported by specified ripple current values and frequency coefficients.
• Industrial and commercial power modules — Use in assemblies that need robust electrolytic capacitance with clear endurance and leakage specifications.

Unique Advantages

• High ripple-current endurance: Rated ripple current of 2.17 A (120 Hz) and 3.255 A (50 kHz) enables sustained operation under ripple stress.
• Proven high-temperature life: Endurance tested for 3000 hours at 105°C under rated ripple conditions, with controlled limits on capacitance change, tan δ, and leakage current.
• Wide operating range: –40°C to +105°C operating temperature range for the 200–250 V rating supports a broad set of environmental conditions.
• Design-ready form factor: Snap-in radial can (φ25 × 25 mm) simplifies PCB mounting and mechanical retention in power assemblies.
• Specification transparency: Clear electrical parameters (leakage formula, tan δ limits, impedance ratios) help with predictable thermal and electrical design margins.
• RoHS compliant: Meets current RoHS directives for restricted substances.
