LNR1H683MSEN

The LNR1H683MSEN is a screw-terminal aluminum electrolytic capacitor offering 68 mF (68,000 μF) at a 50 V rating in a radial can package. Designed for general-purpose power applications, it provides high bulk capacitance, substantial ripple current capability, and a robust endurance profile for demanding DC systems.

Its screw-terminal construction and φ51 × 100 mm form factor make it suitable for installations requiring secure bolted connections and easy replacement or maintenance. Key durability characteristics include a 5,000 hour endurance at 85 °C and RoHS compliance.

Key Features

• Capacitance and Voltage: 68 mF (68,000 μF) rated at 50 V for high bulk energy storage and DC bus support.
• High Ripple Current Handling: Rated ripple current of 11 A at 120 Hz and 12.65 A at 100 kHz to support high-current filtering and smoothing.
• Endurance and Stability: 5,000 hours at 85 °C under D.C. bias plus rated ripple current; capacitance change is specified within ±15% after endurance testing per the datasheet.
• Temperature Range: Operating from –40 °C to +85 °C (applicable to the 10–100 V range as specified in the series datasheet).
• Loss and Leakage: Specified tangent of loss angle (tan δ) of 0.25; leakage current limit after 5 minutes is not more than 3√(C·V) μA or 5 mA, whichever is smaller (measured at 20 °C).
• Rugged Screw-Terminal Package: Radial can with screw terminals and standard φ51 mounting bracket arrangement; nominal bolt diameter for φ51 units is M5 for secure electrical and mechanical connection.
• Size and Packaging: Body dimensions φ51 × 100 mm (diameter × length); supplied in cardboard packing for mass production handling.
• Regulatory: RoHS compliant.

Typical Applications

• Power supplies: Bulk smoothing and energy storage on DC rails where 68 mF at 50 V and multi-amp ripple handling are required.
• Industrial power electronics: DC bus support and filtering in general-purpose industrial equipment that requires robust, serviceable screw-terminal connections.
• Energy storage / hold-up: Temporary energy buffering and hold-up in systems needing large capacitance and defined endurance at elevated temperatures.

Unique Advantages

• Large bulk capacitance: 68 mF provides significant energy storage in a single component, reducing the number of parallel capacitors needed.
• High ripple capability: 11 A (120 Hz) and 12.65 A (100 kHz) ripple ratings enable use in high-current smoothing and filtering applications.
• Proven endurance: 5,000 hours at 85 °C under rated conditions with controlled capacitance drift and specified tan δ limits for predictable lifetime performance.
• Secure screw-terminal mounting: Radial can with screw terminals and M5 bolt compatibility for robust mechanical and electrical connections in field-serviceable designs.
• Wide ambient range: –40 °C to +85 °C operation (for the 10–100 V range) supports deployment across varied environments.
• Regulatory compliance: RoHS status documented for environmentally conscious designs.
