LGW2W151MELZ40

The LGW2W151MELZ40 is a snap-in terminal aluminum electrolytic capacitor from Nichicon's LGW series. It delivers 150 µF capacitance at a 450 V rating in a radial, can-style snap-in package designed for general-purpose applications.

Engineered for high ripple-current environments, this component withstands 3000 hours of application of rated ripple current at 105°C and is RoHS compliant. Its polarized design and snap-in mounting make it suitable for robust power-related circuitry where sustained ripple handling is required.

Key Features

• Capacitance & Voltage: 150 µF nominal capacitance with a 450 V rated voltage and ±20% tolerance (120 Hz, 20°C).
• High Ripple-Current Endurance: Designed to withstand 3000 hours of rated ripple current at 105°C, providing predictable long-term performance under continuous ripple stress.
• Ripple Current Performance: Rated ripple current values include 1.22 A at 120 Hz and 1.745 A at 50 kHz, supporting a range of frequency conditions.
• Operating Temperature Range: Specified for operation from −25°C to +105°C.
• Package & Mounting: Radial, can-style snap-in package with snap-in terminals for secure board installation and polarization marking for correct orientation.
• Reliability Characteristics: Meets endurance requirements for capacitance change, tan δ, and leakage current after the specified 3000-hour ripple-current endurance test at 105°C.
• RoHS Compliance: Compliant with the RoHS directive (2011/65/EU,(EU)2015/863).
• Physical Size: Body dimensions approximately L: 4 × D: 2.2 cm (radial can, snap-in).

Typical Applications

• General-Purpose Power Circuits: Use where a polarized, high-voltage capacitor with strong ripple-current endurance is required for energy storage and smoothing.
• High-Ripple Environments: Suitable for circuits that subject capacitors to sustained ripple current up to the rated values and require 3000-hour endurance at 105°C.
• Board-Level Power Modules: Snap-in mounting provides reliable board retention for radial assemblies in commercial and industrial equipment.

Unique Advantages

• Extended Endurance under Ripple Stress: 3000 hours at 105°C under rated ripple current ensures stable capacitance and controlled tan δ over long operating periods.
• High Voltage Capability: 450 V rating enables use in higher-voltage general-purpose applications while maintaining electrolyte performance.
• Frequency-Responsive Ripple Handling: Published ripple-current values at 120 Hz and 50 kHz give designers concrete performance metrics across common frequency ranges.
• Snap-In Mechanical Retention: Radial snap-in terminals provide secure PCB mounting suitable for assemblies that benefit from robust mechanical retention.
• Regulatory Compliance: RoHS compliance supports use in assemblies requiring restriction-of-hazardous-substances conformance.
