LGN2D122MELC30

The LGN2D122MELC30 is a 1.2 mF (1200 µF), 200 V polarized aluminum electrolytic capacitor in a snap-in, large-can package from Nichicon's LGN series. It is designed for general-purpose power applications that require high capacitance, high ripple-handling capability and a compact snap-in form factor.

Key value propositions include high ripple endurance at elevated temperature (3000 hours at 105°C), a controlled dissipation factor (tan δ) measured at 20°C/120 Hz, and RoHS compliance—making it suitable for production environments that demand robust, long-life power filtering and energy storage components.

Key Features

• Capacitance & Voltage — 1.2 mF (1200 µF) rated at 200 V for bulk energy storage and smoothing in higher-voltage power rails.
• Endurance at Elevated Temperature — Rated life of 3000 hours at 105°C when subjected to rated ripple current, providing predictable long-term performance in hot operating environments.
• High Ripple Current Capability — Low-frequency ripple current of 2650 mA (120 Hz) and high-frequency ripple current of 3975 mA (100 kHz) to support demanding power-supply ripple conditions.
• Low Dissipation Factor — tan δ max 0.15 (measured at 20°C, 120 Hz) for controlled losses and thermal performance.
• Leakage Current — Specified leakage current of 1460 µA after standard conditioning, aiding in predictable start-up and standby behaviour.
• Mechanical & Mounting — Snap-in terminal, radial can package (φ35 × 30 mm) for secure board retention and assembly; supplied in tray packing for production handling.
• Operating Temperature Range — –40°C to +105°C to support a wide range of environmental conditions.
• RoHS Compliant — Meets RoHS directive requirements for restricted substances.

Typical Applications

• Power Supply Bulk Smoothing — Use on higher-voltage DC rails up to 200 V for bulk capacitance and ripple smoothing, leveraging 1200 µF capacitance and high ripple ratings.
• Industrial Power Electronics — Suitable for power conditioning and energy buffering in industrial control equipment where elevated ambient temperatures and continuous ripple are present.
• Switch-Mode Power Supplies — Acts as an output/input reservoir capacitor in SMPS designs requiring robust ripple endurance and stable dissipation factor at 120 Hz and higher frequencies.

Unique Advantages

• Long High-Temperature Endurance — 3000 hours at 105°C ensures sustained performance under continuous ripple stress, reducing maintenance and replacement frequency.
• High Ripple Handling Across Frequencies — Separate ratings for low-frequency (2650 mA at 120 Hz) and high-frequency (3975 mA at 100 kHz) ripple let designers specify the part with confidence for mixed-frequency applications.
• Compact Snap-In Can — φ35 × 30 mm can with snap-in terminals provides a space-efficient, secure mounting solution for high-capacitance needs where board retention and ease of assembly matter.
• Predictable Electrical Losses — Low tan δ (0.15 at 20°C/120 Hz) gives controlled dissipation and helps manage thermal budget in dense power designs.
• Production-Friendly Packaging — Tray packing supports automated handling and consistent supply-chain logistics for volume assembly.
• RoHS Compliance — Conforms to RoHS requirements for regulated-substance control in manufacturing.
