LNR1H683MSEB

The LNR1H683MSEB is an aluminum electrolytic capacitor in a screw-terminal, radial can package offering 68 mF (68,000 µF) capacitance at 50 V. It is designed for general-purpose applications that require high bulk capacitance, robust screw-terminal connections, and sustained performance up to 85°C.

Key value comes from its high ripple-current capability, long endurance rating, and wide operating temperature range, making it suitable for designs where energy storage and reliable power conditioning are required.

Key Features

• High Capacitance & Rated Voltage — 68 mF (68,000 µF) nominal capacitance rated at 50 V for substantial bulk energy storage.
• Screw-Terminal, Radial Can Package — Screw terminal mounting with a radial can and standard bracketing for φ51 and larger sizes provides secure electrical and mechanical connections.
• High Ripple Current Handling — 11,000 mA at 120 Hz (low frequency) and 12,650 mA at 100 kHz (high frequency) for demanding ripple and smoothing workloads.
• Endurance — 5,000 hours at 85°C under rated D.C. bias plus rated ripple current, with defined limits for capacitance change, tan δ, and leakage after endurance testing.
• Wide Operating Temperature — Specified for −40°C to +85°C operation to accommodate a broad range of thermal environments.
• Electrical Characteristics — Polarized capacitor with ±20% capacitance tolerance and a specified tan δ of 0.25; leakage current specified at 5,000 µA.
• Physical Size — Body diameter φ51 mm with 100 mm length (φ51×100L), standard mounting brackets included for φ51 and larger units.
• Environmental Compliance — RoHS compliant.

Typical Applications

• General-purpose power systems — Bulk energy storage and smoothing where high capacitance and screw-terminal connections are required.
• High ripple-current environments — Circuits that must tolerate continuous ripple currents up to 11 A (120 Hz) and 12.65 A (100 kHz).
• Extended-temperature installations — Deployments needing reliable operation across −40°C to +85°C.
• Long-life equipment — Applications that benefit from a specified 5,000-hour endurance at 85°C under rated conditions.
