LGUW6561MELC

The LGUW6561MELC is a Nichicon LGU-Series aluminum electrolytic capacitor in a snap-in terminal configuration. It provides 560 µF capacitance at a 420 V rating in a radial, snap-in can intended for general-purpose power applications.

Designed for sustained operation up to 105°C with robust ripple-current capability and tray packing for board-level assembly, this part targets designs that require high-voltage bulk capacitance with long endurance.

Key Features

• Capacitance & Tolerance — 560 µF nominal with tolerance of −20% to +20% (measured at 120 Hz, 20°C).
• Rated Voltage — 420 V DC rating for high-voltage power circuits.
• High Ripple Current — Low-frequency ripple current 2.15 A at 120 Hz and high-frequency ripple current 3.075 A at 50 kHz to support demanding ripple conditions.
• Low Loss (tan δ) — tan δ = 0.15 measured at 20°C, 120 Hz for controlled dissipation.
• Leakage Current — Specified leakage current of 1450 µA (after 5 minutes’ application of rated voltage at 20°C).
• Thermal Endurance — Rated for operation from −25°C to +105°C with 3000 hours endurance at 105°C under rated ripple conditions.
• Polarized Snap-In Package — Radial, snap-in can (φ35 × 50 mm) for secure PCB mounting.
• Packaging & Availability — Tray packing; product status: mass production. RoHS compliant.

Typical Applications

• General-purpose power systems — Provides bulk capacitance and voltage handling for general-purpose designs that require 420 V operating voltage.
• High-temperature environments — Suitable where operation at elevated temperatures is required, supported by a −25°C to +105°C range and 3000 h endurance at 105°C.
• High ripple-current circuits — Supports circuits with significant AC ripple due to specified low- and high-frequency ripple current ratings.
• Board-level snap-in assemblies — Snap-in radial can and tray packing simplify installation in power electronics assemblies.

Unique Advantages

• High-voltage bulk capacitance: 560 µF at 420 V gives substantial energy storage in a single component for space-efficient designs.
• Long endurance at elevated temperature: Specified 3000 hours at 105°C under rated ripple conditions for extended lifetime in demanding thermal environments.
• Measured ripple capability: Defined ripple current ratings at 120 Hz and 50 kHz allow designers to quantify thermal and lifetime performance under real operating conditions.
• Controlled dissipation: Low loss tangent (tan δ = 0.15 at 20°C, 120 Hz) supports predictable heating and efficiency behavior.
• Manufacturing-ready packaging: Tray packing and mass-production status facilitate procurement and assembly planning.
• Regulatory compliance: RoHS compliant to support environmental and regulatory requirements.
