LGUW6151MELY

The LGUW6151MELY is a Nichicon LGU-series snap-in aluminum electrolytic capacitor designed for general-purpose power applications that require high-voltage capability and durable ripple endurance. This radial can, snap-in terminal device delivers 150 µF capacitance at a rated voltage of 420 V with ±20% tolerance.

Engineered for continuous operation up to 105°C with a 3000-hour endurance rating, the LGUW6151MELY combines high ripple-current handling and low leakage to support demanding power-filtering and DC-link applications in industrial and commercial equipment.

Key Features

• Electrical performance — 150 µF nominal capacitance with ±20% tolerance and a 420 V rated voltage for high-voltage filtering and energy storage.
• High ripple capability — Rated ripple current of 880 mA at 120 Hz (low frequency) and 1.258 A at 50 kHz (high frequency) to handle sustained AC ripple stress.
• Low leakage — Specified leakage current of 750 µA, supporting low-loss DC applications.
• Thermal and endurance rating — Operates from −25°C to +105°C and meets endurance requirements for 3000 hours at 105°C under rated ripple and DC bias.
• Loss characteristics — Tangent of loss angle (tan δ) max. 0.15 for the 160–420 V range (measured at 120 Hz, 20°C), indicating controlled ESR-related losses.
• Mechanical and packaging — φ20 × 50 mm can size in a radial, snap-in package; supplied in tray packing and produced for mass production runs.
• Regulatory — RoHS compliant for restricted substance requirements.

Typical Applications

• Power-supply filtering — Bulk smoothing and ripple reduction in high-voltage power supplies where 420 V rating and substantial ripple capability are required.
• DC-link and energy storage — DC-link decoupling and short-term energy buffering in industrial power electronics benefiting from high ripple endurance and long life at 105°C.
• General-purpose industrial equipment — Suitable for a variety of general-purpose roles in commercial and industrial systems that call for reliable high-voltage electrolytic capacitance.

Unique Advantages

• High-voltage, high-capacitance combination — 150 µF at 420 V provides substantial stored energy in a compact φ20 × 50 mm package for space-constrained designs.
• Design longevity under stress — 3000-hour endurance at 105°C with rated ripple applied offers predictable life for continuous high-temperature operation.
• Effective ripple handling across frequencies — Specified ripple currents at both low (120 Hz) and high (50 kHz) frequencies support a range of switching and line-frequency conditions.
• Low leakage for stable DC performance — 750 µA leakage current supports applications where minimized standby losses and sustained bias are important.
• Production-ready packaging — Tray packing and mass production availability simplify procurement and assembly for high-volume manufacturing.
• RoHS compliant — Meets current restricted-substances requirements for global manufacturing environments.
