LNT1J683MSEB

The LNT1J683MSEB is a screw-terminal aluminum electrolytic capacitor engineered for general-purpose power applications that require high bulk capacitance and robust ripple handling. It provides 68,000 µF at a 63 V rating in a screw-terminal can package designed for secure electrical and mechanical connections.

Built for elevated-temperature operation up to 105°C and produced for mass-production supply with cardboard packing, this capacitor targets designs where high stored energy, sustained ripple current capability, and RoHS compliance are required.

Key Features

• High Capacitance & Voltage — 68,000 µF nominal capacitance with a 63 V rated voltage and ±20% tolerance, delivering significant bulk energy storage per component.
• Screw Terminal Mounting — Radial can with screw terminals provides secure, low-impedance connections suitable for robust power assemblies and repeatable installation.
• High Temperature Rating — Rated for operation from −40°C to +105°C, enabling use in elevated-temperature environments.
• Endurance at Elevated Temperature — Specified lifetime of 2,000 hours at 105°C under rated conditions, with defined limits for capacitance change, dissipation factor, and leakage current after life test.
• Ripple Current Capability — Handles 13.5 A at 120 Hz and 15.53 A at 100 kHz, supporting applications with substantial AC ripple on DC links.
• Compact Screw-Can Mechanical Size — Physical form factor: φ76.2 × 120L (listed also as L: 12 × D: 7.62 cm), suitable where large capacitance must be packaged in a screw-terminal can.
• RoHS Compliant — Conforms to RoHS requirements for restricted substances.
• Production-Ready Packaging — Supplied for mass production with cardboard packing to support manufacturing logistics.

Typical Applications

• Power Supply Filtering — Used for bulk smoothing and decoupling in general-purpose power supplies where large capacitance and ripple handling are required.
• Energy Storage — Suitable for applications that require significant stored charge for hold-up or transient energy delivery.
• DC Link / Power Electronics — Employed in power conversion systems to stabilize DC link voltage under variable load and ripple conditions.

Unique Advantages

• Large-Capacity Single Component — 68,000 µF reduces the component count for bulk energy storage compared with multiple smaller capacitors.
• High Ripple Handling — Specified ripple currents at both low and high frequencies enable reliable operation in demanding ripple environments.
• Secure Screw-Terminal Connections — Facilitates strong, serviceable electrical connections for heavy-current applications.
• Wide Operating Temperature Range — −40°C to +105°C rating supports deployment in elevated-temperature equipment.
• Production & Environmental Readiness — Mass-production packaging and RoHS compliance streamline procurement and regulatory considerations.
• Defined Lifetime Performance — Lifetime and endurance specifications at 105°C provide predictable performance planning for design and maintenance cycles.
