LGU2D271MELY

The LGU2D271MELY is an aluminum electrolytic, snap-in terminal capacitor designed for general-purpose power applications. It delivers 270 µF capacitance at a 200 V rating with ±20% tolerance and is built for sustained operation up to 105°C.

This part combines high ripple-current capability, low loss (tan δ = 0.15 at 20°C and 120 Hz), and long endurance (3000 hours at 105°C) in a compact φ20 × 30 mm can with snap-in mounting and tray packing suitable for mass production.

Key Features

• Rated Capacitance & Voltage — 270 µF at 200 V with ±20% tolerance for bulk energy storage and DC link stabilization.
• Snap-in Radial Can Package — Snap-in terminal type and radial can package for secure board mounting and high-current connections; size listed as φ20 × 30L (L: 3 × D: 2 cm).
• High-Temperature Endurance — Qualified for 3000 hours of operation at 105°C under rated ripple current conditions, supporting prolonged use in hot environments.
• High Ripple Current Capability — 1.10 A at 120 Hz (low frequency) and 1.65 A at 50 kHz (high frequency) to handle significant AC components on DC rails.
• Low Loss — tan δ of 0.15 measured at 20°C and 120 Hz for efficient performance with reduced heating from dielectric losses.
• Controlled Leakage — Leakage current specified at 690 µA, consistent with stable DC performance after voltage application.
• Wide Operating Temperature Range — Rated for −40°C to +105°C, enabling use across a broad range of environmental conditions.
• RoHS Compliant — Meets RoHS directive requirements for restricted substances.

Typical Applications

• Industrial Power Supplies — Bulk smoothing and ripple suppression on 200 V rails where high ripple current and 105°C endurance are required.
• Power Conversion Modules — DC link and energy-storage capacitor for converters and inverters that demand stable capacitance under thermal stress.
• Backup & Hold-up Circuits — Energy buffering and hold-up time support where controlled leakage and long life are important.

Unique Advantages

• Long Endurance at Elevated Temperature: 3000-hour rating at 105°C provides predictable lifetime behavior under continuous ripple stress.
• High Ripple Capability Across Frequencies: Specified ripple currents at 120 Hz and 50 kHz support both mains-frequency smoothing and higher-frequency switching environments.
• Low Dielectric Loss: tan δ = 0.15 at 20°C/120 Hz reduces internal heating and helps maintain performance over temperature and time.
• Compact Snap-in Form Factor: φ20 × 30 mm can with snap-in terminals offers a space-efficient solution for high-voltage DC rails in rack and board-level power systems.
• RoHS Compliance: Conforms to RoHS requirements for deployment in regulated product lines.
