LGUW6331MELB

The LGUW6331MELB is a Nichicon LGU series aluminum electrolytic capacitor in a snap‑in terminal configuration. It provides 330 µF capacitance at a 420 V rated voltage with snap‑in radial can packaging and tray packing for board‑level installation.

Designed for general‑purpose power applications, the component delivers long‑term endurance at elevated temperatures and robust ripple handling, making it suitable where high‑voltage bulk capacitance and reliable thermal performance are required.

Key Features

• Capacitance & Voltage — 330 µF nominal capacitance rated at 420 V for high‑voltage bulk energy storage and filtering.
• High‑temperature Endurance — Rated for operation up to 105°C with an endurance specification of 3000 hours at 105°C when subjected to rated ripple current.
• Ripple Current Performance — Low‑frequency ripple current of 1.45 A (120 Hz) and high‑frequency ripple current of 2.074 A (50 kHz) support demanding power conversion and filtering loads.
• Loss Characteristics — tanδ (DF) of 0.15 measured at 20°C, 120 Hz, indicating controlled dissipation suitable for power applications at the rated voltage.
• Leakage and Tolerance — Specified leakage current of 1110 µA and capacitance tolerance of ±20% (–20% to +20%), specified at 20°C and 120 Hz.
• Package & Mounting — Snap‑in radial can (φ30 × 45 mm) with tray packing for efficient board assembly and handling.
• RoHS Compliant — Conforms to RoHS requirements as noted in the product documentation.

Typical Applications

• General‑purpose power circuits — Bulk smoothing and energy storage in high‑voltage power stages where 420 V capability and 330 µF capacitance are required.
• Power conversion equipment — Filtering and ripple management in power supplies and converters that operate at elevated temperatures up to 105°C.
• Industrial and commercial electronics — Board‑mounted snap‑in solution for robust, long‑life filtering in general‑purpose industrial systems.

Unique Advantages

• High‑voltage capability: 420 V rating enables use in higher DC bus and power systems without compromise to capacitance.
• Long life at elevated temperature: 3000 hours endurance at 105°C under rated ripple current provides predictable lifetime behavior in hot operating environments.
• Strong ripple handling: Specified low‑ and high‑frequency ripple currents support both mains‑frequency smoothing and higher‑frequency switching ripple suppression.
• Snap‑in mounting for secure board retention: Radial snap‑in can design simplifies panel and board assembly for robust mechanical retention.
• Clear electrical specifications: Defined tanδ, leakage current and tolerance values make it straightforward to evaluate for design and reliability margins.
• RoHS compliance: Meets RoHS requirements to support regulatory needs for many commercial and industrial products.
