LGU2A392MELC

The LGU2A392MELC is a snap-in terminal type aluminum electrolytic capacitor designed for general-purpose electronic equipment. It is a polarized radial can capacitor rated 100 V with a capacitance of 3.9 mF and a capacitance tolerance of ±20%.

Engineered for elevated-temperature operation, this capacitor is specified for use from –40°C to 105°C and is endurance-rated to withstand 3000 hours of D.C. bias plus rated ripple current at 105°C. The LGU2A392MELC is RoHS compliant for environmentally conscious designs.

Key Features

• Snap-in Terminal Package: Radial, can-style snap-in mounting for secure board retention and simplified installation in through-hole assemblies.
• High Temperature Endurance: Rated to operate up to 105°C with an endurance specification of 3000 hours under D.C. bias plus rated ripple current.
• Capacitance and Voltage: 3.9 mF nominal capacitance at a rated voltage of 100 V with a tolerance of −20% to +20%.
• Ripple Current Capability: Rated ripple current of 3.69 A at 120 Hz and 4.244 A at 50 kHz, suitable for applications that require sustained ripple handling at these frequencies.
• Wide Operating Temperature Range: −40°C to 105°C, supporting a broad range of ambient conditions.
• Polarized Design: Polarized electrolytic construction for DC bulk energy storage and filtering functions in power circuits.
• Regulatory Compliance: Compliant to the RoHS directive (2011/65/EU, (EU)2015/863).
• Physical Size: Package footprint approximately L: 4.5 × D: 3.5 cm in a radial can, snap-in form factor.

Typical Applications

• General-Purpose Power Supplies: Bulk energy storage and ripple smoothing in general-purpose DC power conversion and regulation circuits.
• Industrial Electronics: Filtering and decoupling in industrial control and power distribution equipment where elevated temperature endurance is required.
• Power Conditioning: AC/DC and DC/DC stages that require polarized electrolytic capacitance with sustained ripple current capability.

Unique Advantages

• High-Temperature Reliability: Specified to withstand 3000 hours at 105°C under rated ripple conditions, supporting long-duration high-temperature operation.
• Solid Ripple Handling: Explicit ripple current ratings at 120 Hz (3.69 A) and 50 kHz (4.244 A) provide quantifiable performance for design verification.
• Wide Ambient Range: −40°C to 105°C operating range accommodates varied environmental conditions without derating beyond the stated limits.
• RoHS Compliant: Meets current RoHS directives for lead-free and restricted-substance requirements.
• Robust Snap-in Mounting: Radial snap-in terminals provide mechanical stability for through-hole assemblies and secure PCB retention.
