LGL2W561MELC40

The LGL2W561MELC40 is a Nichicon LGL series aluminum electrolytic capacitor in a snap-in, radial can package. It delivers 560 µF capacitance at a 450 V rating in a compact φ35 × 40 mm can, designed for general-purpose high-voltage power circuits.

Engineered for reliability in demanding thermal and ripple environments, this part supports continuous operation to 105°C and is supplied in tray packing for high-volume production.

Key Features

• Capacitance & Voltage: 560 µF rated capacitance at 450 V for bulk energy storage and filtering in high-voltage circuits.
• Package & Mounting: Snap-in radial can (φ35 × 40 mm) for secure mechanical mounting and straightforward PCB installation.
• Temperature Range & Endurance: Operating temperature –25°C to +105°C with endurance specified as 2000 hours at 105°C under DC bias plus rated ripple current.
• Ripple Performance: Rated ripple current 1.66 A at 120 Hz and 2.374 A at 50 kHz; frequency coefficient reaches 1.43 at 50 kHz or more for elevated ripple capability at higher frequencies.
• Tolerance & Polarization: Capacitance tolerance ±20% and polarized construction; designed for polarized high-voltage applications.
• Leakage & Loss Characteristics: Leakage current specified as I ≤ 3√(C·V) µA after 5 minutes at 20°C; tan δ max 0.20 at 450 V (measurement at 120 Hz, 20°C).
• Series Reliability Features: Stability at low temperature with Z(–25°C)/Z(+20°C) ≤ 8 and defined post-endurance limits (capacitance within ±20%, tan δ ≤ 200% of initial spec, leakage ≤ initial spec).
• Production Packaging: Tray packing suitable for mass production and automated handling.

Typical Applications

• High-voltage power supplies: Bulk filtering and smoothing where 450 V dielectric and 560 µF capacitance are required.
• DC-link and inverter circuits: Energy storage and ripple handling in industrial power conversion systems operating up to 105°C.
• UPS and power conditioning: High-voltage smoothing and transient energy support for standby and conditioning equipment.

Unique Advantages

• High-voltage capability: 450 V rating enables use in high-voltage power circuits without upsizing multiple components.
• Compact snap-in form factor: φ35 × 40 mm radial can with snap-in terminals simplifies board mounting and delivers mechanical stability.
• Designed for elevated temperature operation: Rated for −25°C to +105°C with 2000 hours endurance at 105°C, providing predictable long-term behavior under thermal stress.
• Defined ripple specifications: Explicit ripple current ratings at 120 Hz and 50 kHz plus frequency coefficients allow accurate thermal and lifetime budgeting for designers.
• Measurable leakage and loss limits: Leakage current formula and tan δ limits provide clear acceptance criteria for quality control and circuit reliability analysis.
• Production-ready packaging: Tray-packed for mass production reduces handling risk and supports automated assembly lines.
