LGU2W151MELB

The LGU2W151MELB is a Nichicon LGU series aluminum electrolytic capacitor in a snap‑in terminal, radial can package. It is rated 150 µF at 450 V with polarized construction and ±20% tolerance, designed for general-purpose applications.

This part delivers high-voltage capability with specified ripple handling (880 mA at 120 Hz and 1.258 A at 50 kHz), low loss (tan δ = 0.2 at 20°C, 120 Hz), and long endurance (3000 hours at 105°C), providing reliable bulk energy storage and smoothing in demanding environments.

Key Features

• Core Electricals — 150 µF capacitance at 450 V with ±20% tolerance; polarized design suitable for DC energy storage and smoothing.
• Ripple Performance — Rated ripple current of 880 mA at 120 Hz and 1.258 A at 50 kHz enables effective handling of both low- and high-frequency ripple conditions.
• Low Loss — Specified tangent of loss angle (tan δ) of 0.2 at 20°C, 120 Hz for predictable dissipation characteristics.
• Thermal & Endurance — Operating temperature range of –25°C to 105°C and endurance of 3000 hours at 105°C under rated ripple current and DC bias.
• Leakage Current — Characterized leakage current of 770 µA, enabling reliable performance after voltage application.
• Mechanical & Mounting — Snap‑in terminal, radial can package (φ30 × 30L / 3 × 3 cm), supplied in tray packing for board-level assembly.
• Environmental — RoHS‑compliant construction.

Typical Applications

• General-purpose power supplies — Bulk smoothing and energy storage at high DC voltages using the 450 V rating and specified ripple currents to reduce voltage ripple.
• High-voltage DC link filtering — Providing DC link capacitance where long endurance at elevated temperature (3000 h at 105°C) and high ripple capability are required.
• Industrial power electronics — Supporting filtering and decoupling in industrial converters and power modules that operate at higher voltages and elevated temperatures.

Unique Advantages

• High-voltage rating: 450 V rating enables use in higher-voltage DC applications without stacking multiple capacitors.
• Validated ripple endurance: Rated ripple currents at both low and high frequencies provide confidence in handling real-world ripple spectra.
• Long high-temperature life: 3000 hours endurance at 105°C under rated conditions supports longevity in thermally demanding systems.
• Compact snap‑in package: φ30 × 30L radial can with snap‑in terminals simplifies secure board mounting and mechanical retention.
• Defined electrical loss and leakage: Specified tan δ and leakage current values enable predictable thermal and leakage behavior in designs.
• Production-ready supply: Tray packing and mass production status aid volume procurement and assembly workflows.
