LGU2P471MELZ

The LGU2P471MELZ is a Nichicon LGU series aluminum electrolytic capacitor in a snap-in terminal can package, specified for general-purpose electronic applications. It provides 470 µF capacitance at a 220 V rating with polarized construction and snap-in mounting for secure board attachment.

Designed for applications requiring sustained performance at elevated temperatures, this part endures 3000 hours of rated ripple current at 105°C and is RoHS compliant.

Key Features

• Electrical Performance: 470 µF nominal capacitance with a rated voltage of 220 V and capacitance tolerance of ±20% (–20% to +20%).
• High-temperature Endurance: Specified endurance of 3000 hours at 105°C under D.C. bias plus rated ripple current, with limits on capacitance change, tan δ and leakage current defined by the LGU series specifications.
• Ripple Current Capability: Rated ripple current of 1.45 A at 120 Hz and 2.175 A at 50 kHz, enabling sustained AC stress handling in appropriate circuit conditions.
• Temperature Range: Operating temperature range from –40°C to +105°C for the 220 V rating.
• Mounting & Package: Snap-in radial can package for PCB installation; package dimensions approximately L: 4.0 cm × D: 2.2 cm and a maximum seated height of 1.575 inch.
• Polarized Design: Polarized electrolytic capacitor intended for circuits that accommodate polarity requirements.
• Environmental Compliance: RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• General-purpose electronic equipment: Use where a 470 µF, 220 V polarized capacitor with snap-in mounting is required for energy storage and smoothing.
• Power assemblies and modules: Suitable for designs that require endurance at elevated temperatures and continuous ripple handling per the specified ripple current ratings.
• Industrial control systems: For circuits needing a robust aluminum electrolytic with long-duration high-temperature performance.

Unique Advantages

• Proven high-temperature endurance: 3000 hours at 105°C provides predictable lifetime behavior in elevated-temperature environments.
• High-voltage capability: 220 V rating supports applications requiring higher DC voltage handling without changing capacitor topology.
