LGU2G151MELB

The LGU2G151MELB is a Nichicon aluminum electrolytic capacitor in a snap‑in terminal (radial can) package designed for general purpose applications. It offers 150 µF capacitance at a 400 V rated voltage with polarization and a rated operating range to 105°C.

Designed to withstand demanding ripple conditions, this part endures 3000 hours of rated ripple current at 105°C and is RoHS compliant, making it suitable where high‑voltage smoothing and long‑term thermal endurance are required.

Key Features

• Capacitance & Voltage: 150 µF nominal capacitance with a 400 V rated voltage and ±20% tolerance, suitable for high‑voltage filtering and energy storage within its rating.
• High‑Temperature Endurance: Rated for operation up to 105°C and guaranteed to withstand 3000 hours of rated ripple current at 105°C.
• Ripple Current Performance: Rated ripple current of 880 mA at 120 Hz and 1.258 A at 50 kHz, supporting continuous ripple handling in AC‑biased circuits.
• Mounting & Package: Snap‑in terminal, radial can package for secure board attachment and straightforward installation in panel or chassis mounted power assemblies.
• Polarized Electrolytic: Polarized configuration for DC applications requiring electrolytic capacitance.
• Environmental Compliance: Compliant with RoHS (2011/65/EU, (EU)2015/863).
• Compact Dimensions: Physical size L: 2.5 × D: 3 cm, enabling dense placement in power modules and assemblies.

Typical Applications

• General Purpose Electronics — Used where a 400 V, 150 µF polarized capacitor with high‑temperature endurance is required for bulk capacitance or decoupling.
• Power Modules and Converters — Employed for DC link smoothing and ripple attenuation in assemblies that operate at elevated temperatures and require sustained ripple handling.
• Industrial Equipment — Suitable for industrial power circuitry needing reliable high‑voltage electrolytic capacitance with long thermal life.

Unique Advantages

• Long Endurance at Elevated Temperature: Specified to withstand 3000 hours of rated ripple current at 105°C, providing predictable life performance in hot environments.
• High Voltage Capability: 400 V rating supports designs that require high DC voltage handling without series stacking.
• Measured Ripple Ratings: Published ripple current values at 120 Hz and 50 kHz (880 mA and 1.258 A respectively) allow engineers to size capacitors against actual ripple conditions.
• Robust Snap‑In Mounting: Snap‑in terminal and radial can packaging enable secure mechanical mounting and repeatable assembly in power chassis.
• Regulatory Compliance: RoHS conformity reduces environmental compliance overhead for regulated product lines.
• Compact Footprint: 2.5 × 3 cm envelope permits integration into space‑constrained power designs.
