LGU2W101MELZ

The LGU2W101MELZ is a Nichicon LGU-series aluminum electrolytic capacitor in a radial, snap-in can package designed for general-purpose power applications. It delivers 100 µF capacitance at a 450 V rating with polarized construction and snap-in terminals for secure mounting.

Key value propositions include high-voltage capability, designed endurance at elevated temperature, and defined ripple-current handling for power systems that require reliable bulk capacitance under load.

Key Features

• Capacitance & Voltage — 100 µF rated capacitance at 450 V for high-voltage bulk energy storage and filtering.
• Snap-in Radial Can Package — Radial, can-type snap-in mounting intended for robust chassis or PCB assembly with snap-in terminals.
• High-Temperature Endurance — Engineered to withstand 3000 hours of rated ripple current at 105°C, meeting the LGU series endurance criteria.
• Operating Temperature Range — Specified range of −25°C to +105°C for 315–450 V parts, supporting elevated-temperature operation.
• Ripple Current Ratings — Rated ripple current of 690 mA at 120 Hz and 986.7 mA at 50 kHz, demonstrating usable high-frequency performance.
• Tolerance & Polarization — Capacitance tolerance ±20% and polarized construction for conventional electrolytic use.
• Regulatory — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).
• Compact Dimensions — Size L: 3.5 × D: 2.2 cm for designs where board area and height profile are constrained.

Typical Applications

• General-purpose power filtering — Provides bulk capacitance and smoothing in general-purpose power systems requiring a 450 V rating.
• High-temperature power assemblies — Suited for equipment where components must tolerate continuous operation up to 105°C with 3000 hours rated ripple endurance.
• Snap-in mounted power modules — Used where snap-in radial can mounting is preferred for secure mechanical and electrical installation.

Unique Advantages

• High-voltage capability: 450 V rating enables use in higher-voltage power rails and bulk storage applications without upsizing to larger packages.
• Proven thermal endurance: Designed to meet LGU-series endurance requirements of 3000 hours at 105°C under rated ripple current, helping ensure long-term stability in hot operating environments.
• Defined ripple performance: Documented ripple current values (690 mA at 120 Hz, 986.7 mA at 50 kHz) allow precise thermal and lifetime budgeting in power designs.
• Secure snap-in mounting: Radial snap-in terminals provide reliable mechanical retention for chassis or PCB installations where vibration or handling are considerations.
• Regulatory compliance: RoHS compliance supports deployment in regions and products that require restricted-substance conformance.
• Compact footprint: 3.5 × 2.2 cm can dimensions make it suitable where space-efficient high-voltage capacitance is required.
