LGU2D222MELC

The LGU2D222MELC is a snap-in terminal aluminum electrolytic capacitor from Nichicon’s LGU series. It delivers 2200 µF capacitance at a 200 V rated voltage in a radial, snap-in can package designed for general-purpose power applications.

Engineered for extended operation at elevated temperatures, this part supports high ripple currents and a 3000-hour endurance at 105°C, making it suitable for designs that require robust bulk energy storage, smoothing and filtering under sustained load.

Key Features

• Capacitance & Voltage: 2.2 mF (2200 µF) rated at 200 V with ±20% tolerance, providing substantial bulk capacitance for DC link and smoothing applications.
• Snap-in Terminal, Radial Can: Snap-in mounting simplifies secure board installation and mechanical retention in power assemblies.
• High Ripple Current Capacity: Rated ripple current of 3.78 A at 120 Hz (low frequency) and 5.67 A at 50 kHz (high frequency), supporting circuits with significant AC ripple components.
• Low Loss (tan δ): tan δ ≤ 0.15 measured at 20°C, 120 Hz, indicating controlled dissipation for the 160–420 V voltage class to help manage self-heating.
• Extended Endurance: Withstanding 3000 hours of rated ripple current at 105°C, meeting the LGU series endurance criteria for long-term operation at elevated temperature.
• Wide Operating Range: Operational from −40°C to +105°C, accommodating varied thermal environments.
• Physical Profile & Packaging: φ35 × 50 mm (D × L) radial can; supplied in tray packing and available in mass production quantities.
• Regulatory Compliance: RoHS compliant.

Typical Applications

• General-purpose power electronics: Provides 2200 µF at 200 V with high ripple capability for bulk energy storage and smoothing in power assemblies where sustained ripple current is present.
• Power supply filtering: Supports combined low- and high-frequency ripple handling—3.78 A at 120 Hz and 5.67 A at 50 kHz—to reduce voltage ripple on DC rails.
• Industrial power conversion: Snap-in radial can and extended 3000-hour endurance at 105°C suit sustained operation in industrial environments requiring reliable bulk capacitance.

Unique Advantages

• High-voltage bulk capacitance: 2200 µF at 200 V supplies substantial stored energy for DC link and reservoir needs without parallel modules.
• Designed for sustained ripple loading: Specified ripple currents at both low and high frequencies reduce thermal stress and support long-term operation under AC loading conditions.
• Proven endurance at elevated temperature: 3000 hours at 105°C with defined post-test limits for capacitance, tan δ and leakage current supports predictable lifetime performance.
• Robust thermal range: −40°C to +105°C operating window covers a wide set of deployment environments.
• Practical board mounting: Snap-in terminals in a radial can form factor simplify assembly and mechanical retention in power modules and assemblies.
• Regulatory assurance: RoHS compliance aligns the part with common environmental requirements.
