The LNT2W472MSEHBB is a screw-terminal aluminum electrolytic capacitor designed for general-purpose power applications. It provides high-voltage energy storage in a radial can with screw terminals for secure, low-resistance connections.

Engineered for robust operation up to 105°C and featuring long endurance under rated ripple conditions, this capacitor addresses high-voltage smoothing, DC energy storage and high-ripple environments in industrial and power-electronics designs.

Key Features

• Capacitance and Voltage: 4.7 mF (4700 µF) nominal capacitance rated at 450 V for high-voltage energy storage and smoothing.
• Tolerance & Loss: ±20% capacitance tolerance and tan δ (DF) 0.2 at 20°C, 120 Hz for predictable AC loss behavior.
• High Ripple Capability: Low-frequency ripple current 21.7 A (120 Hz) and high-frequency ripple current 30.38 A (100 kHz) to handle substantial AC stress under load.
• Leakage Current: Specified leakage current 4360 µA after application of rated voltage, aiding predictable standby and bias behavior.
• Temperature & Endurance: Operating range −25°C to +105°C with a rated life of 5000 hours at 105°C under rated ripple conditions.
• Mounting & Package: Screw terminal, radial can (φ76.2 × 150 mm), designed for secure bolted connections and mechanical stability; shipped in cardboard packing.
• Environmental Compliance: RoHS compliant for regulatory alignment in lead-restricted designs.

Typical Applications

• General-purpose power filtering: Bulk smoothing and decoupling in high-voltage DC power rails where large capacitance and high ripple capability are required.
• DC energy storage: Energy buffering and charge storage in systems that need 450 V rated components with long endurance at elevated temperature.
• High-ripple power circuits: Circuits subject to substantial AC ripple across a broad frequency range, leveraging the capacitor’s specified low- and high-frequency ripple currents.

Unique Advantages

• High-voltage capacity: 450 V rating enables use in elevated-voltage power systems without series stacking.
• Large stored energy: 4.7 mF (4700 µF) provides significant charge storage for smoothing and transient support.
• Robust ripple handling: Dual-frequency ripple specifications (21.7 A at 120 Hz, 30.38 A at 100 kHz) support designs with mixed-frequency stress.
• Long endurance at elevated temperature: 5000-hour life at 105°C supports sustained operation in thermally demanding environments.
• Screw-terminal mounting: Mechanical reliability and low-contact resistance for secure connections in high-current applications.
• Standards-conscious design: RoHS compliance for compatibility with lead-restricted manufacturing requirements.
