LGU2W820MELZ

The LGU2W820MELZ is a Nichicon LGU‑series aluminum electrolytic capacitor in a snap‑in terminal, radial can package. It delivers 82 µF capacitance at a 450 V rated voltage and is designed for general‑purpose applications that require high‑voltage, high‑temperature performance.

Key value comes from its 105°C endurance rating and long life specification (3000 hours at 105°C), combined with measured ripple and leakage characteristics suitable for demanding power applications where a robust, compact snap‑in capacitor is required.

Key Features

• Capacitance & Tolerance — 82 µF nominal capacitance with tolerance of −20% to +20% (measured at 120 Hz, 20°C).
• High Voltage Rating — Rated voltage of 450 V for high‑voltage applications.
• High‑Temperature Endurance — Rated for operation from −25°C to 105°C with a specified life of 3000 hours at 105°C under rated ripple current and DC bias.
• Ripple Current Performance — Low‑frequency ripple current: 640 mA at 120 Hz; high‑frequency ripple current: 915.2 mA at 50 kHz.
• Loss and Leakage — Tangent of loss angle (tan δ) of 0.20 (measured at 20°C, 120 Hz) and specified leakage current of 570 µA.
• Package and Mounting — Radial snap‑in can package (φ22 × 30 mm) for secure PCB mounting; supplied in tray packing and available in mass production.
• RoHS Compliant — Conforms to RoHS requirements as specified in product information.

Typical Applications

• General‑Purpose Power Systems — Suitable where a high‑voltage, snap‑in electrolytic capacitor is required for bulk capacitance in general‑purpose designs.
• High‑Temperature Environments — Useful in applications that require operation up to 105°C with a 3000‑hour endurance rating at that temperature.
• High‑Voltage Capacitor Arrays — Appropriate for assembling high‑voltage capacitor banks or arrays where compact radial snap‑in components are preferred.

Unique Advantages

• Long Endurance at Elevated Temperature — Specified 3000 hours at 105°C provides predictable long‑term performance under sustained thermal stress.
• High Voltage Capability — 450 V rating supports higher‑voltage designs without compromise to nominal capacitance.
• Measurable Ripple Handling — Specified ripple currents at both low and high frequencies (640 mA at 120 Hz, 915.2 mA at 50 kHz) enable designers to assess thermal and lifetime impacts precisely.
• Controlled Dielectric Losses — tan δ of 0.20 (20°C, 120 Hz) helps quantify dissipation for thermal and efficiency calculations.
• Compact Snap‑In Form Factor — φ22 × 30 mm radial can with snap‑in terminals offers a space‑efficient solution for PCB mounting and secure mechanical retention.
• Production Availability — Status listed as mass production with tray packing for streamlined assembly and procurement.
