LGUW6820MELZ

The LGUW6820MELZ is a Nichicon LGU series snap-in aluminum electrolytic capacitor designed for general-purpose power applications. It delivers 82 µF capacitance at a 420 V rated voltage in a compact snap-in can (φ22 × 25L) and is intended for use where high-voltage filtering and bulk energy storage are required.

Built for elevated-temperature operation, this capacitor is specified to operate from −25°C to 105°C and is endurance-rated for 3000 hours at 105°C with rated ripple current applied, providing predictable performance in demanding thermal environments.

Key Features

• High Voltage Rating — 420 V rated voltage enables application in higher-voltage DC bus and power-supply circuits.
• Capacitance & Tolerance — 82 µF nominal capacitance with ±20% tolerance (measured at 120 Hz, 20°C) for bulk smoothing and decoupling.
• High Ripple Current Capability — Low-frequency ripple current 640 mA (120 Hz) and high-frequency ripple current 915.2 mA (50 kHz) for reliable handling of AC ripple across the frequency spectrum.
• Elevated-Temperature Endurance — Rated life of 3000 hours at 105°C under rated ripple conditions; designed for sustained operation at high case temperatures.
• Low Loss Characteristics — Tangent of loss angle (tan δ) 0.15 measured at 20°C, 120 Hz (per 160–420 V specification), supporting efficient energy storage with controlled dissipation.
• Leakage Current — Specified leakage current of 550 µA (after rated voltage application at 20°C), suitable for power applications requiring defined leakage behavior.
• Robust, Easy Mounting — Snap-in terminal radial can (φ22 × 25L) for secure board retention in bulk power assemblies.
• Regulatory — RoHS compliant.
• Packaging & Availability — Tray packing; product is in mass production.

Typical Applications

• Power Supply Filtering — Bulk smoothing and DC bus filtering in high-voltage power supplies where 420 V rating and 82 µF capacitance are required.
• Industrial Power Electronics — Energy storage and ripple handling in industrial converters and control systems, leveraging the 3000-hour endurance at 105°C.
• High-Voltage DC Link — DC link and charge/discharge buffering where elevated-temperature stability and high ripple current capability are necessary.

Unique Advantages

• High-Voltage Capability: 420 V rating enables use in elevated-voltage circuits without stacking multiple capacitors.
• Temperature-Qualified Endurance: 3000 hours at 105°C under rated ripple current delivers predictable long-term behavior in warm operating environments.
• Frequency-Range Ripple Handling: Distinct ripple current specifications at 120 Hz and 50 kHz provide designers with clear performance across common low- and high-frequency ripple scenarios.
• Compact Snap-In Form Factor: φ22 × 25L radial can with snap-in terminals offers secure mounting for bulk capacitor applications while conserving board space.
• Measured Dissipation: Low tan δ (0.15 at 120 Hz, 20°C for 160–420 V range) supports efficient energy storage with controlled dielectric losses.
• RoHS Compliance: Meets RoHS requirements for reduced hazardous substance content.
