LNX2W102MSEFBN

The LNX2W102MSEFBN is a screw-terminal aluminum electrolytic capacitor from Nichicon’s LNX series designed for high-voltage, high-ripple power applications. With a 1000 µF capacitance at 450 V and a robust screw-terminal package, it targets industrial power supplies and inverter circuitry where sustained ripple handling and long endurance are required.

This part combines high ripple-current capability, extended operational life at elevated temperature, and a compact radial can form factor (φ51 × 80L) to deliver reliable bulk energy storage and smoothing in demanding DC-link and power-filter roles.

Key Features

• Electrical Rating: 1000 µF nominal capacitance at 450 V with ±20% tolerance, suitable for high-voltage DC-link and filter applications.
• Loss Characteristics: tanδ (DF) specified as 0.2 at 20°C and 120 Hz, enabling predictable dissipation and thermal planning.
• High Ripple-Current Capability: 4000 mA (4 A) at 120 Hz for low-frequency ripple and 5600 mA (5.6 A) at 100 kHz for high-frequency ripple, supporting heavy ripple-loading conditions.
• Leakage Current: Specified leakage current of 2010 µA, provided for accurate standby and fault current budgeting.
• Long Endurance: Rated for 20,000 hours life under rated ripple current at +85°C, delivering extended service life in continuous-power environments.
• Operating Range and Low-Temperature Stability: Operational from −25°C to +85°C; impedance stability at low temperature is characterized (Z(−25°C)/Z(+20°C) up to 8 for the series).
• Mechanical & Mounting: Screw terminal, radial can (φ51 × 80L), M5 bolt terminal pitch; mounting options supported by common log- and 2-/3-leg brackets.
• Compliance & Packaging: RoHS compliant; supplied in cardboard packing and currently in mass production.

Typical Applications

• Industrial Power Supplies: Bulk energy storage and DC-link smoothing in industrial power supply designs where high voltage and sustained ripple handling are required.
• Inverter Circuits: DC-link and filter capacitor for inverter modules, supporting continuous ripple currents and long-term endurance at elevated temperatures.
• High-Voltage Power Electronics: Energy buffering and decoupling in high-voltage converter stages that demand 450 V electrical rating and screw-terminal robustness.

Unique Advantages

• High-Voltage, High-Capacity Solution: 450 V rating paired with 1000 µF capacitance provides substantial energy storage for DC-link and filter duties without multiple parallel parts.
• Designed for Sustained Ripple Stress: Specified ripple currents at both low and high frequencies (4 A @120 Hz, 5.6 A @100 kHz) reduce thermal stress and improve reliability under real-world loading.
• Long Service Life at Elevated Temperature: 20,000 hours endurance at +85°C under rated ripple current supports long maintenance intervals and predictable end-of-life planning.
• Robust Screw-Terminal Packaging: Radial can with screw terminals (M5) enables secure, low-resistance connections suited to high-current power paths and mechanical retention.
• Predictable Loss and Leakage Parameters: Specified tanδ and leakage current figures enable accurate thermal and leakage budgeting in system-level designs.
• RoHS-Compliant and Production-Ready: Environmentally compliant construction and mass-production status streamline procurement and design-in timelines.
