LGU2W101MELY

The LGU2W101MELY from Nichicon is a snap-in terminal aluminum electrolytic capacitor in the LGU series, rated 450 V with 100 µF nominal capacitance and ±20% tolerance. Designed for general-purpose high-voltage applications, it delivers long-term ripple endurance and stable performance up to 105°C.

Key value propositions include a 3000-hour endurance at 105°C under rated ripple current, low dissipation factor (tan δ = 0.20 at 20°C, 120 Hz), and robust ripple-handling capability—packaged as a radial, snap-in can and supplied in tray packing for production use.

Key Features

• Electrical Rating 100 µF nominal capacitance at 450 VDC with ±20% tolerance, suitable for high-voltage DC circuits requiring capacitance stability.
• High-Temperature Endurance Specified endurance of 3000 hours at 105°C when subjected to rated ripple current and DC bias, meeting LGU series endurance requirements.
• Ripple Current Performance Rated ripple current of 690 mA at 120 Hz and 986.7 mA at 50 kHz, supporting sustained ripple handling in demanding applications.
• Low Losses Maximum tangent of loss angle (tan δ) of 0.20 at 20°C, 120 Hz for the 450 V rating, enabling efficient energy use and lower heating.
• Leakage Current Specified leakage current of 630 µA, measured after standard voltage application at 20°C.
• Mounting & Package Snap-in terminal, radial can (φ20 × 45L dimension: L 4.5 × D 2 cm) designed for secure board mounting; supplied in tray packing for assembly efficiency.
• Environmental Compliance RoHS compliant.

Typical Applications

• Power supply smoothing and ripple control — Provides sustained ripple handling and DC bias endurance up to 105°C for high-voltage power rails.
• High-voltage DC circuits — 450 V rating and 100 µF capacitance support energy storage and decoupling in high-voltage designs.
• General-purpose industrial and commercial electronics — Suitable where long life, RoHS compliance, and snap-in mounting are required.

Unique Advantages

• Long-term high-temperature reliability: 3000-hour rated endurance at 105°C under rated ripple conditions reduces maintenance and replacement frequency.
• Strong ripple-handling capability: High specified ripple currents at both low and high frequencies minimize voltage ripple and heating in service.
• Low dissipation for efficient operation: tan δ = 0.20 at 20°C/120 Hz for the 450 V rating helps limit internal losses during operation.
• High-voltage rating: 450 V nominal rating enables use in higher-voltage DC applications without component substitution.
• Production-ready packaging: Tray packing and mass production status simplify procurement and assembly for volume builds.
• Regulatory compliance: RoHS compliance supports environmentally regulated product lines.
