LNT2W332MSEGBN

The LNT2W332MSEGBN is a Nichicon LNT series aluminum electrolytic capacitor in a screw-terminal can designed for high-voltage, high-capacitance general-purpose power applications. It provides 3.3 mF nominal capacitance at a 450 V rated voltage in a robust radial screw-terminal package sized φ63.5 × 150 mm.

Engineered for sustained operation up to 105°C with a 5,000-hour rated life, this part delivers high ripple-current capability and secure screw-terminal mounting for reliable connections in industrial and power-electronics environments.

Key Features

• Core Electrical Specs — 3.3 mF (3300 µF) nominal capacitance with a tolerance of −20% to +20% at 20°C, 120 Hz; polarized design for DC applications.
• High Voltage Rating — Rated voltage 450 V, suitable where elevated DC voltage handling is required.
• Low Loss Characteristic — Tangent of loss angle (tan δ) 0.2 measured at 20°C, 120 Hz, for predictable AC loss behavior.
• High Ripple-Current Capability — Low-frequency ripple current 16.5 A (120 Hz) and high-frequency ripple current 23.1 A (100 kHz) to support demanding power smoothing and filtering tasks.
• Reliable Endurance — Rated for 5,000 hours at 105°C under specified ripple conditions, with capacitance and tan δ endurance limits defined by the series specification.
• Robust Mechanical / Mounting — Screw terminal, radial can package (φ63.5 case) with nominal bolt size M5 and terminal pitch 28.6 mm for secure, serviceable connections.
• Operational Temperature Range — Specified for −25°C to +105°C for 160 to 500 V products in the series, matching this 450 V part’s temperature class.
• Packaging & Production Status — Supplied in cardboard packing and currently in mass production.
• Regulatory — RoHS-compliant.

Typical Applications

• General-purpose power supplies — Bulk smoothing and energy buffering where high DC voltage and substantial capacitance are required to stabilize supply rails.
• Industrial power electronics — Filtering and ripple suppression in high-voltage converters and inverters that require high ripple-current handling.
• Energy-storage and bus capacitors — Local energy reservoir and decoupling in systems needing sustained high-voltage capacitance with long-term thermal endurance.

Unique Advantages

• High-voltage, high-capacitance combination — 3.3 mF at 450 V provides substantial bulk capacitance in a single radial screw-terminal can, reducing the need for multiple smaller parts.
• Designed for high ripple loads — Specified LF and HF ripple currents (16.5 A / 23.1 A) enable handling of both low- and high-frequency ripple without compromising performance.
• Long thermal endurance — 5,000-hour life rating at 105°C supports sustained operation in elevated-temperature environments.
• Secure, serviceable connections — Screw terminal and M5 bolt provisions simplify installation and replacement in equipment racks and panels.
• Predictable electrical behavior — Specified tan δ and leakage current figures (tan δ 0.2; leakage 3650 µA) allow engineers to design accurately for loss and standby current budgets.
• RoHS-compliant and production-ready — Standard packaging and mass-production status support procurement and volume deployment.
