LGX2D222MELC50

The LGX2D222MELC50 is a 2200 µF, 200 V aluminum electrolytic capacitor from Nichicon’s LGX series featuring a snap-in terminal radial can. Designed for general-purpose power electronics, it is suited for rectifier circuits in inverters and switching power supplies where long-term endurance and high ripple handling are required.

Key value propositions include long-life assurance at elevated temperatures, high ripple-current capability across low and high frequencies, and a compact snap-in package for robust mounting in mass-production assemblies.

Key Features

• Capacitance & Voltage — 2.2 mF (2200 µF) rated at 200 V for bulk energy storage and smoothing in power rails.
• Endurance / Reliability — Rated for 5000 hours at 105°C when subjected to DC bias plus rated ripple current, providing long life in high-temperature applications.
• High ripple-current capability — Handles 3450 mA at 120 Hz (low frequency) and 5175 mA at 50 kHz (high frequency) for demanding filtering and rectification tasks.
• Leakage current specification — Specified leakage current of 1980 µA; datasheet leakage formula I ≤ 3√CV (µA) applies after 5 minutes at 20°C.
• Operating temperature range — −25°C to +105°C to support a wide range of industrial environments.
• Package & termination — Snap-in terminal, radial can package in a φ35 × 50 mm body (35 mm diameter × 50 mm length) for secure chassis or PCB mounting; supplied in tray packing for mass production.
• Tolerance & polarity — ±20% capacitance tolerance at 120 Hz, 20°C; polarized capacitor.
• RoHS compliant — Meets RoHS environmental requirements.

Typical Applications

• Inverter rectifiers — Bulk smoothing and energy storage in rectifier stages of general inverters, leveraging the LGX’s long-life and high ripple capability.
• Switching power supplies — Output filtering and hold-up capacitors where sustained ripple current and endurance at 105°C are required.
• Industrial power electronics — General-purpose filtering and decoupling in industrial converters and power modules operating across −25°C to +105°C.

Unique Advantages

• Long-life assurance: 5000 hours rated endurance at 105°C improves service life and reduces replacement frequency in high-temperature designs.
• High ripple-current handling: 3.45 A at 120 Hz and 5.175 A at 50 kHz enable effective smoothing in both low- and high-frequency power circuits.
• High-voltage capability: 200 V rating supports higher-voltage rails and provides design headroom for many power-electronics topologies.
• Robust snap-in package: Radial can with snap-in terminals and φ35 × 50 mm footprint simplifies mechanical retention and assembly for production environments.
• Manufacturing-ready supply: Tray packing and mass-production availability support scalable deployment and streamlined BOM sourcing.
• Documented performance limits: Leakage current and tan δ specifications and the datasheet endurance criteria provide verifiable parameters for reliability assessments.
