LNT2W392MSEGBN

The LNT2W392MSEGBN is a screw-terminal aluminum electrolytic capacitor in Nichicon’s LNT series, rated 3.9 mF (3900 µF) at 450 V. It is a polarized radial can with M5 screw terminals and a φ63.5 × 170 mm can size, designed for general-purpose high-voltage applications requiring substantial capacitance and high ripple handling.

Key value propositions include a 450 V rated voltage, high ripple-current capability at both low and high frequencies, a 5000-hour endurance at 105°C, and RoHS compliance—features that support reliable filtering and energy-storage roles in demanding power systems.

Key Features

• Capacitance & Voltage — 3.9 mF (3900 µF) rated at 450 V for high-voltage DC energy storage and smoothing.
• Screw-Terminal Mounting — Radial can with screw terminals (M5 pitch for φ63.5) enables robust, low-resistance electrical connections and secure mechanical mounting.
• High Ripple Current — Low-frequency ripple current 18.3 A (120 Hz) and high-frequency ripple current 25.62 A (100 kHz) for effective ripple absorption across frequency ranges.
• Endurance at Elevated Temperature — Rated life of 5000 hours at 105°C under specified conditions, supporting long-term operation in hot environments.
• Electrical Losses — Tangent of loss angle (tanδ) of 0.2 measured at 20°C, 120 Hz, enabling predictable dissipation characteristics.
• Leakage Current — Specified leakage current of 3970 µA after rated voltage application, useful for design margining in power circuits.
• Operating Temperature Range — –25°C to +105°C, aligned with the LNT series operating window for 160–500 V parts.
• Compliance & Packaging — RoHS compliant and supplied in cardboard packing; part is in mass production.

Typical Applications

• High-Voltage Power Supplies — Provides bulk energy storage and smoothing for 450 V DC rails, helping stabilize output under load.
• Industrial Inverters & Drives — Acts as a DC-link or buffer capacitor where high ripple current capability and elevated temperature endurance are required.
• Energy Storage & Filtering — Suitable for filtering and decoupling in power conversion systems that need large capacitance at high working voltage.

Unique Advantages

• High Voltage Capacity: 450 V rating paired with 3.9 mF capacitance supports significant energy storage in compact high-voltage circuits.
• Robust Ripple Handling: Specified ripple currents at 120 Hz and 100 kHz give designers predictable thermal and electrical performance across low and high-frequency components of ripple.
• Long Elevated-Temperature Life: 5000 hours at 105°C supports extended operation in hot system compartments, reducing maintenance frequency.
• Secure Mechanical & Electrical Connections: Screw-terminal radial can construction simplifies high-current terminations and mechanical retention for heavy-duty applications.
• Measured Dissipation Characteristics: Known tanδ at standard test conditions (0.2 at 20°C, 120 Hz) helps with thermal and ESR budgeting in designs.
• Regulatory Compliance: RoHS compliance supports use in regions requiring restricted substances conformity.
