LNT2W681MSEF

The LNT2W681MSEF is a screw‑terminal aluminum electrolytic capacitor designed for general‑purpose power electronics requiring high voltage handling and robust ripple performance. It delivers 680 µF at a 450 V rating in a radial can with screw terminals, packaged for cardboard shipment and available in mass production.

Engineered for continuous operation up to +105°C and a rated endurance of 5,000 hours at that temperature, this capacitor targets applications that demand sustained DC‑link energy storage, high ripple tolerance and reliable long‑term operation in industrial environments.

Key Features

• Capacitance & Voltage: 680 µF nominal capacitance at a 450 V rated voltage for high‑voltage DC filtering and energy storage.
• Tolerance & Dissipation: ±20% capacitance tolerance; tan δ (DF) 0.2 maximum at 20°C, 120 Hz for predictable loss behavior.
• High Ripple Capability: 4.4 A low‑frequency ripple current at 120 Hz and 6.16 A high‑frequency ripple current at 100 kHz to handle both mains‑frequency and switching ripple.
• Leakage Current: 1,650 µA specified leakage current (measured per product data) after rated voltage application.
• Endurance & Temperature Range: 5,000 hours life at +105°C; operating temperature range −25°C to +105°C for elevated‑temperature reliability.
• Package & Termination: Radial can with screw terminals (φ51 × 100L size); terminal pitch and bolt sizing follow the LNT series dimensions for φ51 (nominal bolt M5).
• Compliance & Availability: RoHS‑compliant and in mass production for consistent supply.

Typical Applications

• Power Supplies: DC‑link and bulk filtering in high‑voltage power supplies where 450 V rating and high ripple current capability are required.
• Industrial Drives & Inverters: Energy buffering and smoothing in motor drive and inverter front ends that operate at elevated temperatures and require long endurance.
• Uninterruptible Power Systems (UPS): Bulk energy storage and ripple suppression for DC buses in UPS and backup power systems.
• Power Conversion Equipment: Filtering in high‑voltage converters and rectifier stages where screw‑terminal mounting and robust ripple handling simplify assembly and maintenance.

Unique Advantages

• High‑Voltage Capability: 450 V rating enables use in higher‑voltage DC systems without additional series stacking.
• Dual‑Band Ripple Performance: Specified ripple current at both 120 Hz and 100 kHz supports designs subject to mains and switching ripple components.
• Long Endurance at Elevated Temperature: 5,000 hours at +105°C provides predictable life for demanding thermal environments.
• Screw‑Terminal Robustness: Radial can with screw terminals (φ51 size with M5 nominal bolt) simplifies field wiring and mechanical mounting for heavy‑current applications.
• Clear Electrical Parameters: Explicit tan δ, leakage current and tolerance specifications enable straightforward reliability and thermal management calculations.
• Production‑Ready Supply: Mass production status and RoHS compliance support volume deployment and regulatory requirements.
