LGX2W151MELB25

The LGX2W151MELB25 is a snap‑in terminal aluminum electrolytic capacitor from Nichicon's LGX series. It delivers 150 µF capacitance at a 450 V rating in a compact φ30 × 25 mm can for general‑purpose power applications.

Designed for power conversion and filtering, the part combines long life endurance with high ripple capability, making it suitable for rectifier circuits in inverters and switching power supplies where sustained performance at up to 105°C is required.

Key Features

• Capacitance & Voltage — 150 µF capacitance rated at 450 V for high‑voltage DC link and filtering applications.
• Long‑life Endurance — 5000 hours rated lifetime at 105°C, specified under rated ripple and DC bias conditions.
• High Ripple Current Handling — 930 mA at 120 Hz (low frequency) and 1.33 A at 50 kHz (high frequency) to support demanding ripple environments.
• Low Leakage — Specified leakage current of 770 µA after voltage application.
• Electrical Losses — Tan δ of 0.20 (max.) measured at 20°C, 120 Hz for the 450 V rating.
• Temperature Range — Operating from −25°C to +105°C to suit elevated operating environments.
• Package & Mounting — Radial can, snap‑in terminal configuration in a φ30 × 25 mm footprint; supplied in tray packing and in mass production status.
• Environmental Compliance — RoHS compliant.

Typical Applications

• Inverter Rectifier Circuits — Bulk and smoothing capacitor for rectifier stages in general inverter designs.
• Switching Power Supplies — Output and intermediate DC filtering where high voltage and ripple endurance are required.
• General Purpose Power Filtering — Decoupling and energy storage in industrial power conversion and control equipment.

Unique Advantages

• Proven long‑life capability: 5000 hours at 105°C provides predictable aging characteristics for designs requiring extended operating life.
• High ripple tolerance: Specified ripple currents at both low and high frequencies support robust performance in switch‑mode and inverter topologies.
• Compact snap‑in form factor: φ30 × 25 mm can with snap‑in terminals simplifies secure PCB mounting while conserving board area.
• Low leakage: 770 µA leakage current helps maintain efficiency and reduce standby losses in DC systems.
• Wide operating range: −25°C to +105°C supports use across a variety of industrial temperature environments.
• Regulatory compliance: RoHS conformity for environmental assurance in production builds.
