LGL2W271MELB30

The LGL2W271MELB30 is an aluminum electrolytic, snap-in terminal capacitor designed for general-purpose applications. It delivers 270 μF at a 450 V rating in a compact φ30 × 30 mm can with snap-in mounting for robust board retention.

Engineered for high-voltage circuits, the part combines a wide operating temperature range (–25°C to +105°C) and a 2000-hour endurance at 105°C with rated ripple performance, making it suitable where sustained voltage, ripple handling and long-term reliability are required.

Key Features

• Capacitance and Voltage — 270 μF nominal capacitance at a rated voltage of 450 V for high-voltage bulk storage and filtering.
• Operating Temperature & Endurance — Specified for –25°C to +105°C with 2000 hours life at 105°C under rated conditions.
• Snap-in, Radial Can Package — Snap-in terminal type in a radial, can-style package (φ30 × 30 mm) for secure mounting and ease of assembly.
• Ripple Current Performance — 930 mA at 120 Hz (low frequency) and 1.33 A at 50 kHz (high frequency), with frequency coefficients provided for ripple scaling.
• Electrical Loss and Leakage — Tangent of loss angle (tan δ) up to 0.20 at 20°C, 120 Hz; specified leakage current listed at 1040 μA.
• Capacitance Tolerance & Polarization — ±20% tolerance at 120 Hz, 20°C; polarized component for DC applications.
• Packaging and Production — Tray packing and available for mass production.

Typical Applications

• General-purpose power equipment — Bulk energy storage and smoothing in high-voltage DC circuits where 450 V rating and high ripple tolerance are required.
