LGU2W221MELC

The LGU2W221MELC from Nichicon is a snap‑in terminal aluminum electrolytic capacitor in the LGU series, rated for 450 V and 220 µF with ±20% capacitance tolerance. It is a polarized, radial can snap‑in package designed for general‑purpose applications that require high‑voltage bulk capacitance and reliable ripple handling.

Engineered for elevated operating temperatures, the device is specified for operation from −25°C to 105°C and is endurance‑tested for 3000 hours at 105°C under rated ripple current conditions, providing predictable performance in demanding power environments.

Key Features

• High Voltage & Capacitance: 450 V rated voltage with 220 µF nominal capacitance suitable for high‑voltage bulk energy storage in general‑purpose power circuits.
• Snap‑in Mounting, Radial Can: Snap‑in terminal type and radial can package provide secure mechanical retention for vertical mounting and common PCB footprint options.
• High Ripple Current Endurance: Rated ripple current of 1.12 A at 120 Hz and 1.602 A at 50 kHz supports sustained AC ripple handling under load.
• Long High‑Temperature Life: Endurance specified as 3000 hours at 105°C with DC bias plus rated ripple current; capacitance change and dissipation factor remain within defined limits after test.
• Low Leakage & Dissipation: Specified leakage current of 940 µA and a tangent of loss angle (tan δ) of 0.20 at 120 Hz, 20°C for the 450 V rating.
• Operating Range: Rated for −25°C to +105°C operation, matching the LGU series’ 105°C standard for higher temperature applications (315–450 V category).
• Compliance & Production: RoHS‑compliant construction, tray packing, and mass production availability.

Typical Applications

• General‑Purpose Power Systems: Provides high‑voltage bulk capacitance for general‑purpose power circuitry where 450 V rating and robust ripple endurance are required.
• Industrial Power Modules: Suitable for vertical mount installations in industrial power equipment that operate at elevated temperatures and require long endurance at rated ripple current.
• High‑Voltage Filtering/Decoupling: Used where low leakage and controlled dissipation factor are needed to maintain stable performance in high‑voltage DC link and filter networks.

Unique Advantages

• 450 V, 220 µF in a single component: Delivers substantial high‑voltage capacitance without parallel components, simplifying BOM and board layout.
• Proven 105°C Endurance: 3000‑hour rated life at 105°C under ripple load provides predictable aging and reliability for elevated‑temperature deployments.
• High ripple capability across frequencies: Specified ripple currents at both low (120 Hz) and high (50 kHz) frequencies enable versatile use across power conversion topologies.
• Secure snap‑in mounting: Snap‑in terminals and radial can construction provide mechanical robustness for vertical mounting and automated assembly processes.
• Controlled electrical loss and leakage: tan δ = 0.20 and leakage current ~940 µA help maintain efficiency and predictable leakage behavior in high‑voltage circuits.
• RoHS compliant and production ready: Environmentally compliant construction and tray packing support volume manufacturing and regulatory needs.
