LGU2D122MELC

The LGU2D122MELC is an aluminum electrolytic, snap‑in terminal capacitor from Nichicon’s LGU series designed for general‑purpose power applications. It provides 1.2 mF capacitance at a 200 V rating with a rugged snap‑in radial can package and tray packing for production deployment.

Engineered for high ripple environments and elevated operating temperatures, this unit combines high ripple‑current capability, controlled loss (tan δ), and a long 3000‑hour endurance at 105°C to support reliable performance in demanding power systems.

Key Features

• Capacitance & Voltage — 1.2 mF (1200 µF) nominal capacitance with a 200 V rated voltage and ±20% tolerance for bulk energy storage and smoothing.
• High Ripple‑Current Handling — Rated ripple current of 2.65 A at 120 Hz (low frequency) and 3.975 A at 50 kHz (high frequency) to support circuits with significant AC ripple.
• Low Loss and Leakage — Tangent of loss angle (tan δ) 0.15 at 20°C, 120 Hz, and measured leakage current of 1460 µA, enabling predictable ESR/DF behavior and manageable standby losses.
• High‑Temperature Endurance — Qualified for 3000 hours at 105°C under rated ripple conditions, with an operating temperature range of −40°C to +105°C for thermal robustness.
• Snap‑in Radial Package — φ35 × 35L can with snap‑in terminals for secure PCB mounting; supplied in tray packing and available for mass production volumes.
• RoHS Compliant — Manufactured in compliance with RoHS requirements for restricted substances.

Typical Applications

• Industrial Power Supplies — Bulk filtering and smoothing where a 200 V rated capacitor with 1200 µF capacity and high ripple tolerance is required.
• Power Conversion and Drives — Filtering and DC energy buffering in power conversion circuits that demand sustained ripple handling and elevated temperature endurance.
• Uninterruptible Power and Backup Systems — Energy storage and discharge smoothing in backup power circuits relying on long endurance at 105°C and controlled leakage.

Unique Advantages

• Designed for High Ripple Environments: Specified ripple currents at both low and high frequencies ensure the capacitor can handle substantial AC stress without immediate degradation.
• Long Endurance at Elevated Temperature: 3000 hours at 105°C under rated ripple current gives predictable life characteristics for thermal‑stress applications.
• Predictable Electrical Performance: Low tan δ (0.15 at 20°C, 120 Hz) and a measured leakage current provide consistent loss and leakage profiles for design margin planning.
• Robust Mechanical Package: Snap‑in radial can (φ35 × 35L) and tray packing support reliable board mounting and production handling for high‑volume assembly.
• Compliance and Production Ready: RoHS compliant and listed as mass production status for supply chain continuity and regulatory alignment.
