LGUW6121MELY

The LGUW6121MELY is a Nichicon LGU series aluminum electrolytic capacitor in a snap‑in terminal format designed for general‑purpose power applications. It provides 120 µF capacitance at a 420 V rated voltage with polarized construction and tray packing for mass production.

Engineered for high‑voltage systems, this part delivers sustained ripple handling and long endurance at elevated temperatures, making it suitable for applications that require robust energy storage and smoothing at up to 105°C operating temperature.

Key Features

• Capacitance & Voltage: 120 µF capacitance rated at 420 V for high‑voltage energy storage and smoothing.
• Ripple Current Handling: 750 mA low‑frequency ripple current at 120 Hz and 1.073 A high‑frequency ripple current at 100 kHz to support demanding power filtering loads.
• Tolerance & Polarization: ±20% capacitance tolerance at 120 Hz, 20°C; polarized construction for DC applications.
• Endurance & Temperature Range: 3000 hours endurance at 105°C; operating temperature range −25°C to 105°C for sustained high‑temperature performance.
• Leakage Current: Initial leakage current specified at 670 µA.
• Package & Mounting: φ20×40 mm can (L: 4 × D: 2 cm) in a radial snap‑in package for secure board mounting and efficient assembly.
• Environmental Compliance: RoHS‑compliant construction.

Typical Applications

• High‑voltage power supplies: Bulk smoothing and energy storage in 420 V power rails and converters where 120 µF capacitance is required.
• Industrial power equipment: Filtering and ripple suppression in industrial inverters and power modules operating up to 105°C.
• Commercial electronics: General‑purpose DC power filtering in commercial systems that benefit from snap‑in mounting for reliable board installation.

Unique Advantages

• 420 V rating: Enables deployment in higher‑voltage circuits without series stacking.
• High ripple capacity: Combines 750 mA at 120 Hz and 1.073 A at 100 kHz to manage both low‑ and high‑frequency ripple currents.
• Long high‑temperature life: 3000 hours endurance at 105°C supports durability in elevated‑temperature environments.
• Compact snap‑in form factor: φ20×40 mm can with snap‑in terminals for robust mechanical mounting and streamlined assembly.
• RoHS compliance: Meets environmental substance regulations for global product integration.
