LNT1J683MSE

The LNT1J683MSE is a screw‑terminal aluminum electrolytic capacitor from Nichicon's LNT series. It delivers high bulk capacitance (68 mF) at a rated voltage of 63 V in a radial can with screw terminals for secure mechanical and electrical connections.

Engineered for general‑purpose power applications, this capacitor combines high ripple current capability and a wide operating temperature range (−40°C to +105°C), providing reliable bulk energy storage and smoothing in industrial and commercial equipment where robust, serviceable mounting is required.

Key Features

• High Capacitance & Voltage — 68 mF (68,000 µF) rated at 63 V for substantial bulk energy storage in compact screw‑terminal packaging.
• Robust Ripple Current Handling — Low‑frequency ripple current of 13.5 A (120 Hz) and high‑frequency ripple current of 15.53 A (100 kHz) to support demanding power circuits.
• Temperature and Endurance — Rated for operation from −40°C to +105°C with a specified life of 2000 hours at 105°C under rated ripple and bias conditions.
• Electrical Loss and Leakage — Specified tanδ (DF) of 0.5 (measured at 20°C, 120 Hz) and leakage current specified as 5000 µA for predictable loss and self‑discharge characteristics.
• Mechanical / Mounting — Radial can with screw terminals and M5 hardware compatibility (φ76.2 case size) for secure bolt‑down connections in rack or chassis installations.
• Packaging & Availability — Supplied in cardboard packing and listed as mass production status; RoHS‑compliant.

Typical Applications

• General‑Purpose Power Electronics — Use where large bulk capacitance and screw‑terminal mounting are required for energy storage or smoothing on DC rails.
• Industrial Power Supplies — Suitable for power supply filter stages that demand high ripple current capability and stable performance up to 105°C.
• Chassis‑Mounted Energy Storage — Screw‑terminal design enables secure mounting and high current connections in cabinet and rack assemblies.

Unique Advantages

• Substantial Bulk Capacitance: 68 mF at 63 V provides significant energy reserve for smoothing and transient support, reducing the need for parallel components.
• High Ripple Current Capacity: Rated for 13.5 A (120 Hz) and 15.53 A (100 kHz), enabling operation in applications with continuous AC ripple or switching noise.
• Wide Operating Temperature Range: −40°C to +105°C operation with a 2000‑hour life rating at 105°C for dependable performance in elevated ambient conditions.
• Secure Screw‑Terminal Mounting: Radial can with screw terminals (φ76.2 case) provides durable electrical and mechanical connections for serviceable installations.
• Predictable Electrical Behavior: Specified tanδ and leakage current values support straightforward thermal and loss budgeting in power designs.
• Production Readiness: Mass production availability and cardboard packing simplify procurement and handling for volume projects.
