LNT2E681MSEN

The LNT2E681MSEN is a screw‑terminal aluminum electrolytic capacitor designed for general‑purpose power applications. It offers 680 µF capacitance at 250 V in a robust radial can with screw terminals, delivering bulk energy storage and filtering in systems that require high voltage handling and secure electrical connections.

Built for elevated operating conditions, this part supports operation up to 105°C with a specified load life at temperature, and provides measurable ripple current capability across low and high frequencies for demanding power circuits.

Key Features

• Capacitance & Voltage — 680 µF nominal capacitance rated for 250 V to support bulk filtering and energy storage.
• High‑temperature operation — Rated for −25°C to +105°C operation with a lifetime specification of 2000 hours at 105°C.
• Screw terminal mounting — Radial can with screw terminals for secure, low‑impedance connections suitable for higher current paths and field maintenance.
• Ripple current capability — 1.4 A at 120 Hz and 1.68 A at 100 kHz to handle AC ripple across common power frequency and high‑frequency switching applications.
• Mechanical footprint — Compact φ35 × 80L profile (size L: 8 cm × D: 3.5 cm) that balances capacitance with a small installed area for screw‑terminal cans.
• Polarized design — Electrolytic (polar) capacitor suited for DC bias applications.
• RoHS compliant — Meets RoHS requirements for environmental compliance.

Typical Applications

• Power supplies — Bulk filtering and energy storage in general‑purpose DC power supplies and power modules.
• Industrial control equipment — Smoothing and decoupling in control panels and drive electronics that benefit from secure screw‑terminal connections.
• Uninterruptible power systems — Bulk energy buffering and ripple attenuation in UPS and backup power modules.
• Power conversion — Energy storage and ripple suppression in inverters and DC‑DC converters used in general‑purpose equipment.

Unique Advantages

• High voltage capability: 250 V rating enables use in higher‑voltage DC systems without series configuration.
• Designed for elevated temperature: 105°C rating and a defined 2000‑hour lifetime at that temperature give predictable endurance in hot environments.
• Robust screw‑terminal package: Facilitates secure mechanical and electrical connections, simplifying installation and maintenance.
• Frequency‑tested ripple handling: Specified ripple currents at 120 Hz and 100 kHz provide clear performance expectations across common power frequency ranges.
• Compact cylindrical form factor: φ35 × 80L dimensions deliver substantial capacitance in a small footprint for space‑constrained panels.
• RoHS compliance: Supports environmental and regulatory requirements for equipment manufacturing.
