LGU2W470MELY

The LGU2W470MELY is a Nichicon LGU series aluminum electrolytic capacitor in a snap-in radial can package designed for general-purpose power applications. It is a polarized, high-voltage capacitor specified at 47 µF and 450 V with a rated operating range up to 105°C and RoHS compliance.

Engineered to withstand sustained ripple stress, this part endures 3000 hours of rated ripple current application at 105°C, making it suitable for designs that require long-term high-temperature ripple endurance in a snap-in mounting format.

Key Features

• Capacitance & Voltage — 47 µF capacitance at a rated voltage of 450 V for high-voltage energy storage and filtering in compact form.
• High-temperature Endurance — Specified to withstand 3000 hours of rated ripple current at 105°C as defined by the LGU series endurance test.
• Operating Temperature — Rated for operation from −25°C to 105°C (category temperature per 315–450 V range).
• Ripple Current Ratings — Rated ripple current of 390 mA at 120 Hz and 557.7 mA at 50 kHz, supporting AC ripple handling across common frequencies.
• Package & Mounting — Radial, snap-in can package for secure board mounting and mechanical stability in power assemblies.
• Tolerance & Polarity — Capacitance tolerance of −20% to +20% and polarized construction.
• Regulatory Compliance — Compliant with RoHS directives (2011/65/EU, (EU)2015/863).
• Compact Dimensions — Package footprint approximately L: 2.5 × D: 2.0 cm with a low-profile height suitable for constrained assemblies.

Typical Applications

• General-purpose power electronics — Provides high-voltage capacitance for bulk energy storage and smoothing in systems that require 450 V rated components and high-temperature ripple endurance.
• Industrial control equipment — Snap-in mounting and sustained 105°C endurance make it suitable for rugged power sections in industrial assemblies.
• Power supply filtering — 47 µF at 450 V supports filtering and decoupling where polarized electrolytics are required and space is constrained.

Unique Advantages

• High-voltage capability: 450 V rating enables use in higher-voltage power rails without combining multiple lower-voltage components.
• Proven thermal endurance: 3000 hours at 105°C under rated ripple current helps ensure longevity in elevated-temperature operating environments.
• Reliable board attachment: Snap-in radial can package delivers mechanical stability and straightforward PCB insertion for production assemblies.
• Frequency-aware ripple handling: Published ripple current values at 120 Hz and 50 kHz allow designers to assess performance across common ripple frequencies.
• Regulatory alignment: RoHS compliance supports deployment in regions and products that require restricted substance adherence.
• Compact footprint: Small L × D dimensions facilitate integration into space-constrained power designs.
