LNT2V681MSEF

The LNT2V681MSEF is a screw-terminal aluminum electrolytic capacitor from Nichicon’s LNT series, rated 350 V with 680 µF capacitance. It is a radial, can-type capacitor with screw terminals designed for general-purpose power applications that require high-voltage capacitance and secure mechanical connection.

Key value propositions include a wide operating range to +105°C, a long-rated life under full ripple load, and RoHS compliance—features that support durable performance in demanding power circuits.

Key Features

• Electrical Rating — 680 µF capacitance at a rated voltage of 350 V with ±20% tolerance, providing stable bulk energy storage for high-voltage circuits.
• Loss and Stability — Specified tangent of loss angle (tanδ) of 0.2, enabling predictable dissipation characteristics at the measurement conditions provided.
• Ripple Current Performance — Rated ripple current of 4.1 A at 120 Hz and 5.74 A at 100 kHz, supporting AC ripple handling across low and high frequency conditions.
• High-Temperature Endurance — Rated lifetime of 5,000 hours at +105°C when subjected to DC bias plus rated ripple current, for sustained operation at elevated temperature.
• Operating Temperature Range — Specified for operation from −25°C to +105°C to cover a broad range of ambient conditions.
• Mechanical & Mounting — Screw terminal, radial can package (φ51 × 80L); size dimensions L: 8 × D: 5.1 cm and Height Seated Max: 3.15 inch, for secure chassis or bracket mounting.
• Environmental Compliance — RoHS compliant as specified in the product data.

Typical Applications

• General-purpose power circuits — Bulk capacitance and voltage rating for smoothing and energy storage in general-purpose electronic power systems.
• High-temperature installations — Components where sustained operation up to +105°C and a 5,000-hour rated life are required.
• Chassis-mounted power modules — Screw-terminal package provides secure electrical and mechanical connection for mounted power assemblies.

Unique Advantages

• High-voltage bulk capacitance — 680 µF at 350 V delivers substantial energy storage for high-voltage circuits.
• Designed for elevated-temperature endurance — 5,000-hour life at +105°C under rated ripple current supports long-term reliability in hot environments.
• Robust ripple handling — Specified ripple currents at 120 Hz and 100 kHz enable predictable performance across a range of operating frequencies.
• Screw-terminal mounting — Secure mechanical and electrical termination simplifies installation in chassis- or bracket-mounted designs.
• Clear mechanical footprint — φ51 × 80L package with documented L and D dimensions and height specification for straightforward mechanical integration.
• RoHS compliance — Meets environmental directive requirements noted in the product information.
