LGU2A472MELC

The LGU2A472MELC is an aluminum electrolytic capacitor from Nichicon's LGU series, featuring a snap-in terminal can designed for general-purpose power electronics. It provides 4.7 mF capacitance at a 100 V rating, polarized configuration, and is specified for operation from −40 °C to +105 °C.

Engineered for high-ripple and high-temperature applications, this part withstands 3000 hours of rated ripple current at 105 °C and is RoHS compliant, making it suitable for industrial and commercial power filtering and bulk energy-decoupling tasks.

Key Features

• Capacitance and Voltage: 4.7 mF capacitance with a 100 V rated voltage and ±20% tolerance, suitable for bulk energy storage and smoothing in power systems.
• High-Temperature Endurance: Rated for operation up to 105 °C and specified to withstand 3000 hours of D.C. bias plus rated ripple current at 105 °C, supporting demanding thermal environments.
• High Ripple Current Capability: Ripple current ratings of 4.14 A at 120 Hz and 4.761 A at 50 kHz allow effective handling of AC ripple in switching and power-conversion circuits.
• Snap-In Radial Package: Radial, can-type snap-in mounting for secure board retention and straightforward insertion into PCB layouts.
• Polarized Electrolytic Construction: Designed as a polarized capacitor for DC filtering and bulk decoupling applications.
• Environmental Compliance: Compliant with the RoHS directive (2011/65/EU, (EU)2015/863), meeting common environmental regulatory requirements.

Typical Applications

• Power Supply Filtering: Bulk smoothing and output filtering in switch-mode and linear power supplies where high capacitance and durability at elevated temperatures are required.
• Power Conversion Systems: Input and output decoupling in inverters, converters, and industrial power electronics that experience significant ripple currents.
• Industrial Equipment: Energy storage and noise suppression in factory automation and heavy-duty control systems operating in higher ambient temperatures.
• Commercial UPS and Backup Systems: Bulk decoupling and energy buffering for backup power and uninterruptible power supply modules.

Unique Advantages

• Proven High-Temperature Performance: 3000-hour endurance at 105 °C under rated ripple current provides quantifiable reliability for thermal-stressed designs.
• Robust Ripple Handling: Specified ripple current values at both 120 Hz and 50 kHz enable designers to size capacitors confidently for switching-frequency and low-frequency ripple scenarios.
• Secure Snap-In Mounting: Radial snap-in package offers mechanical stability on the PCB, simplifying assembly for medium- to high-current power modules.
• Clear Specification Set: Manufacturer-provided limits for operating temperature, lifetime, and tolerance allow straightforward engineering trade-offs and BOM selection.
• Regulatory Compliance: RoHS conformity supports deployment in environments that require restricted-substance compliance.
