LGUW6151MELA

The LGUW6151MELA is a snap‑in terminal aluminum electrolytic capacitor from Nichicon's LGU series, optimized for general‑purpose high‑voltage power applications. It combines a 420 V rated voltage with 150 µF capacitance and snap‑in mounting to support compact, high‑energy smoothing and filtering tasks where robust ripple handling and long endurance are required.

Designed for operation from −25°C to 105°C with a 3000‑hour endurance at 105°C, this radial can capacitor offers measurable performance metrics—tolerance, dissipation factor, leakage, and ripple ratings—that help engineers size and qualify components for industrial and power electronics designs.

Key Features

• High Voltage Rating — 420 V nominal rated voltage for high‑voltage DC filtering and energy buffering in power conversion circuits.
• Capacitance & Tolerance — 150 µF with ±20% tolerance (measured at 120 Hz, 20°C) for predictable bulk capacitance in supply rails.
• Low Dissipation Factor — tanδ 0.15 (max) at 20°C and 120 Hz, supporting efficient AC performance and lower internal heating under ripple stress.
• Ripple Current Capability — 880 mA at 120 Hz (low frequency) and 1.2584 A at 50 kHz (high frequency), enabling effective smoothing of both low‑ and high‑frequency ripple components.
• Leakage Current — 750 µA specified leakage current after application of rated voltage, aiding in predictable bias behavior.
• Thermal & Endurance Rating — Rated for −25°C to 105°C operating range with 3000 hours life at 105°C under rated ripple and DC bias conditions.
• Package & Mounting — Radial, snap‑in can (φ25 × 35 mm) suited to secured board mounting and tray packing for production handling.
• RoHS Compliant — Meets RoHS requirements for restricted substances.

Typical Applications

• High‑voltage power supplies — Bulk smoothing and energy storage on 420 V DC rails where high ripple endurance and low tanδ are required.
• Industrial power conversion — DC link and filter capacitor for inverters, converters, and motor drive front ends operating within the −25°C to 105°C range.
• Energy buffering — Local energy reservoir in systems that require compact high‑voltage capacitance with snap‑in mounting for secure installation.

Unique Advantages

• High‑voltage capability — 420 V rating enables use on elevated DC buses without stacking multiple lower‑voltage capacitors.
• Measurable ripple performance — Specified ripple currents for both low and high frequencies let designers size capacitors to expected ripple profiles with confidence.
• Long endurance at elevated temperature — 3000 hours at 105°C provides verifiable lifetime data for thermal‑stress planning and reliability assessments.
• Compact snap‑in form factor — φ25 × 35 mm radial can with snap‑in terminals supports dense board layouts and reliable mechanical retention.
• Predictable electrical characteristics — Specified tanδ and leakage current values simplify thermal and leakage budgets in power designs.
