LNX2W472MSEGBB

The LNX2W472MSEGBB is a screw-terminal aluminum electrolytic capacitor from Nichicon’s LNX series, designed for high-voltage, high-ripple power applications. It delivers 4700 µF capacitance at a 450 V rating with a radial can and screw terminal mounting for robust mechanical and electrical connections.

Suited for industrial power supplies and inverter circuitry, this part emphasizes long operational life and high ripple capability, making it appropriate for demanding power-conversion and energy-storage roles where sustained performance at elevated temperature is required.

Key Features

• Capacitance & Voltage — 4.7 mF (4700 µF) nominal capacitance rated at 450 V for high-energy smoothing and bulk storage in power rails.
• Long Life — Rated lifetime of 20,000 hours at +85°C under specified ripple conditions, supporting extended maintenance intervals.
• High Ripple Handling — Standard ripple current capability of 13 A at 120 Hz and 18.2 A at 100 kHz to manage significant AC ripple in converters and inverters.
• Screw Terminal Mounting — Radial can with screw terminals provides secure, low-resistance connections for high-current applications.
• Operating Range & Polarization — Polarized capacitor with operating temperature range from −25°C to +85°C and capacitance tolerance of −20% to +20%.
• Package & Size — Radial can (screw terminals); physical dimensions L: 19 cm × D: 6.35 cm (φ63.5 × 190L).
• RoHS Compliance — Manufactured in compliance with RoHS requirements.
• Series-Level Reliability Options — LNX series offers flame-retardant electrolyte types and extended size ranges for higher capacitance and voltage options.

Typical Applications

• Industrial Power Supplies — Bulk energy storage and smoothing for switched-mode power supplies and power-conditioning systems used in industrial equipment.
• Inverter and Motor Drives — DC bus filtering and ripple absorption in inverter stages and motor drive electronics where high voltage and ripple endurance are required.
• High-Voltage Power Converters — Energy storage and decoupling in high-voltage converter topologies that demand sustained ripple current capacity.

Unique Advantages

• Extended Operational Life: 20,000 hours at 85°C under rated ripple current reduces replacement frequency and supports long-term deployments.
• High Ripple Capability: Measured ripple ratings at both low and high frequencies (13 A at 120 Hz; 18.2 A at 100 kHz) enable reliable filtering across a range of switching systems.
• Robust Mechanical Termination: Screw terminals provide durable, low-impedance connections suited to high-current and high-vibration environments.
• High Voltage Handling: 450 V rating supports use in elevated-voltage DC buses and converter circuits without series stacking.
• Clear Specification Set: Polarized design, operating temperature range (−25°C to +85°C), and defined tolerance (−20% to +20%) simplify design verification and BOM selection.
