LNR1A683MSEN

The LNR1A683MSEN is a screw‑terminal aluminum electrolytic capacitor in Nichicon’s LNR series, offering 68 mF (68,000 µF) capacitance at a 10 V rating in a radial can with screw terminals. It is designed for general‑purpose power applications where large bulk capacitance and robust terminal connections are required.

Key value comes from its high capacitance density, rated ripple current capability across low and high frequency bands, a wide operating temperature range, and a 5,000‑hour endurance at 85°C—making it suitable for sustained DC bias and ripple conditions in industrial and power electronics designs.

Key Features

• High Capacitance — 68 mF (68,000 µF) provides substantial bulk energy storage for smoothing and decoupling in power subsystems.
• 10 V Rated Voltage — Designed for low‑voltage power rails and DC bus applications requiring a 10 V working voltage.
• Screw Terminal Mounting — Radial can with screw terminals allows secure electrical and mechanical connections for high current paths.
• Ripple Current Capability — Low‑frequency ripple: 7.2 A at 120 Hz; high‑frequency ripple: 8.28 A at 100 kHz, supporting demanding ripple load conditions.
• Endurance and Reliability — Rated for 5,000 hours at 85°C under DC bias plus rated ripple current; after endurance the capacitance change remains within ±15% and leakage current meets initial specification.
• Temperature Range — Operating from −40°C to +85°C to cover a wide range of industrial environments.
• Loss Tangent — tanδ (DF) specified as 0.6 measured at 20°C, 120 Hz, enabling predictable dissipation characteristics.
• Leakage Current — Measured leakage current reported at 2,470 µA; datasheet leakage limit follows the standard 3√(C·V) (µA) or 5 mA rule, whichever is smaller.
• Form Factor — Compact φ35 × 80 mm body (L: 8 cm × D: 3.5 cm) with cardboard packing for shipment.
• RoHS Compliant — Meets RoHS environmental requirements.

Typical Applications

• Power Supply Bulk Storage — Large capacitance and high ripple current make the LNR1A683MSEN suitable for energy storage and smoothing on low‑voltage DC rails.
• DC Link and Bus Filtering — Screw terminal connections and robust ripple handling support filtering in power converters and intermediate DC links.
• Industrial Power Electronics — Useful in general‑purpose industrial equipment requiring durable bulk capacitance across −40°C to +85°C and long endurance at elevated temperature.

Unique Advantages

• Substantial Bulk Capacitance: 68,000 µF provides significant energy reserve, reducing the need for multiple smaller parts.
• Dual‑Band Ripple Performance: Specified ripple currents at both 120 Hz and 100 kHz offer predictable behavior across common low‑ and high‑frequency disturbances.
• Screw‑Terminal Robustness: Secure mechanical and electrical connections simplify integration into high‑current PCB or busbar assemblies.
• Endurance at Elevated Temperature: 5,000 hours at 85°C under rated conditions ensures maintained capacitance (±15%) and controlled tanδ increase, supporting long‑term reliability planning.
• Clear Leakage Specification: Documented leakage current value and accepted datasheet limits allow accurate power and standby current budgeting.
• RoHS Compliance: Environmentally compliant material set for regulated designs.
