LGUW6271MELA

The LGUW6271MELA is an aluminum electrolytic capacitor from Nichicon's LGU series featuring a snap‑in terminal radial can. It provides 270 µF capacitance at a 420 V rating and is specified for operation from –25°C to 105°C.

Designed for general‑purpose high‑voltage applications, this snap‑in, tray‑packed capacitor offers long endurance and defined ripple handling for designs that require stable performance at elevated temperatures.

Key Features

• Electrical Performance — 270 µF nominal capacitance with ±20% tolerance, rated at 420 V for high‑voltage circuits.
• Loss Characteristics — tan δ (loss tangent) of 0.15 measured at 20°C, 120 Hz, supporting predictable dissipation characteristics in AC bias conditions.
• Ripple Current Capability — Low‑frequency ripple current of 1.22 A at 120 Hz and high‑frequency ripple current of 1.745 A at 50 kHz for sustained ripple handling.
• Leakage Current — Specified leakage current of 1010 µA after voltage application, enabling reliable bias behavior.
• Temperature and Endurance — Rated operating range of –25°C to 105°C with 3000 hours endurance at 105°C under rated ripple and DC bias.
• Mechanical & Mounting — Snap‑in radial can (φ25×50L / D: 2.5 cm × L: 5 cm) for secure board mounting; supplied in tray packing for handling and assembly.
• Compliance — RoHS compliant and listed as in mass production.

Typical Applications

• General‑purpose high‑voltage systems — Suitable for general‑purpose circuits that require a 420 V rated electrolytic capacitor with elevated temperature endurance.
• Power modules and assemblies — Snap‑in radial construction supports robust board mounting in power assemblies operating up to 105°C.
• High‑temperature environments — Specified 3000 hours endurance at 105°C for applications where long life at elevated temperature is required.

Unique Advantages

• High voltage rating: 420 V rating enables use in higher‑voltage designs without series stacking.
• Long endurance at 105°C: 3000 h life specification under rated ripple current provides a predictable lifetime metric for thermal‑stress designs.
• Defined ripple performance: Explicit low‑ and high‑frequency ripple current ratings (1.22 A at 120 Hz; 1.745 A at 50 kHz) help designers size components for real‑world ripple environments.
• Snap‑in radial package: Secure snap‑in terminal and tray packing streamline mechanical assembly and handling for production environments.
• Measured dissipation: Low tan δ (0.15 at 20°C, 120 Hz) supports predictable loss and thermal behavior in AC‑biased applications.
• Regulatory compliance: RoHS compliance for electronics manufacturing requirements.
