LGU2G820MELZ

The LGU2G820MELZ is a snap-in terminal aluminum electrolytic capacitor from Nichicon's LGU series, specified for general-purpose power applications. It provides 82 µF capacitance at a 400 V rated voltage in a compact φ22 × 25 mm can with a snap-in radial mounting style.

Designed for robust thermal and ripple performance, this part is rated for operation from −25 °C to 105 °C and is endurance-tested for 3000 hours at 105 °C under rated ripple current. It is RoHS compliant and available in tray packaging for production use.

Key Features

• Electrolytic Core and Construction Aluminum electrolytic capacitor in a radial, snap-in can package for secure PCB mounting.
• Rated Voltage & Capacitance 400 V rated voltage with 82 µF nominal capacitance and capacitance tolerance of −20% to +20% (measured at 20 °C, 120 Hz).
• Thermal and Endurance Performance Operating temperature range −25 °C to 105 °C and qualified for 3000 hours at 105 °C when subjected to D.C. bias plus rated ripple current.
• Ripple Current Capability Low-frequency ripple current 640 mA (120 Hz) and high-frequency ripple current 915.2 mA (50 kHz), supporting applications with varying ripple profiles.
• Low Dissipation Factor Tangent of loss angle (tan δ) of 0.15 measured at 20 °C, 120 Hz (typical for the 315–450 V range), indicating controlled dielectric losses.
• Leakage Current Specified leakage current of 540 µA, measured after voltage application at 20 °C.
• Compact Mechanical Footprint Dimensions φ22 × 25 mm (length) keep board area small while providing high-voltage capacitance in a snap-in form.
• Production Ready Part is in mass production and supplied in tray packing for manufacturing environments.

Typical Applications

• General-purpose power filtering: Bulk decoupling and smoothing in equipment that requires a 400 V rated electrolytic capacitor.
• Power supply modules: Filter and energy-storage use in power conversion circuits where snap-in mounting and high-voltage capability are needed.
• Industrial electronics: High-temperature endurance (3000 h at 105 °C) makes this suitable for industrial designs operating up to 105 °C.

Unique Advantages

• High-voltage capability: 400 V rating enables use in higher-voltage supply rails without changing capacitor family.
• Proven endurance at elevated temperature: Rated for 3000 hours at 105 °C under rated ripple current, supporting long-term reliability in hot environments.
• Measured ripple performance across frequencies: Specified ripple current values at 120 Hz and 50 kHz let designers account for both low- and high-frequency ripple loading.
• Controlled dielectric losses: Low tan δ (0.15 at 20 °C, 120 Hz) helps minimize heating and efficiency loss in AC-biased applications.
• Compact snap-in form factor: φ22 × 25 mm can with snap-in terminals for secure mounting and efficient PCB assembly.
• RoHS compliant and production available: Meets RoHS requirements and is supplied in tray packing for streamlined manufacturing.
