LNR1H473MSEN

The LNR1H473MSEN is a screw‑terminal aluminum electrolytic capacitor designed for general‑purpose power applications. It provides a high bulk capacitance of 47,000 µF at a 50 V rating in a radial can with screw terminals, optimized for systems that require substantial energy storage and ripple handling.

Built for robust operation up to 85°C with a 5,000‑hour endurance at that temperature and RoHS compliance, this module targets power electronics, industrial equipment, and commercial systems where high capacitance, reliable lifetime, and secure screw‑terminal mounting are required.

Key Features

• High Capacitance: 47,000 µF (47 mF) rated capacitance for substantial bulk energy storage in power systems.
• Rated Voltage: 50 V working voltage suitable for mid‑voltage power rails and energy buffering.
• Operating Temperature & Endurance: Specified for –40°C to +85°C operation with a rated endurance of 5,000 hours at 85°C; capacitance change is within ±15% after endurance testing per datasheet.
• Ripple Current Capability: 8.6 A at 120 Hz and 9.89 A at 100 kHz, supporting significant AC ripple and decode/rectifier load conditions.
• Low Loss (tan δ): Specified tan δ of 0.25, with endurance limits defined (tan δ ≤ 175% of initial specified value after testing).
• Screw Terminal Mounting: Radial can with screw terminals; for φ51 body size the nominal terminal bolt is M5 and the standard fixture includes a 3‑leg mounting bracket.
• Leakage Current Specification: After 5 minutes at rated voltage leakage current ≤ 3√(C·V) µA or 5 mA, whichever is smaller (measured at 20°C), per datasheet guidance.
• Physical Size & Packaging: Body approximately φ51 mm × 90 mm length (L: 9 × D: 5.1 cm) supplied in cardboard packing for mass production handling.
• RoHS Compliant: Meets RoHS requirements for lead‑free materials and processes.

Typical Applications

• General‑Purpose Power Systems: Bulk energy storage and smoothing on DC rails where a 50 V, 47,000 µF capacitor is required to stabilize voltage and support transient loads.
• Industrial Power Electronics: Filtering and ripple absorption in industrial converters and power supplies benefiting from high ripple current capability and long endurance at 85°C.
• Commercial Equipment: Energy buffering and decoupling in commercial machines and systems that require secure screw‑terminal connections and robust mechanical mounting.

Unique Advantages

• Large Bulk Capacitance: 47,000 µF provides significant energy storage density for designs requiring reduced voltage sag during load transients.
• High Ripple Handling: Specified ripple currents at both 120 Hz and 100 kHz allow designers to size capacitors for rectifier outputs and higher‑frequency switching environments.
• Secure Mechanical Mounting: Screw terminal package with M5 nominal bolt (φ51 size) and a standard 3‑leg bracket improves connection reliability and simplifies chassis attachment.
• Endurance‑Tested Reliability: 5,000 hours at 85°C with defined limits for capacitance, tan δ, and leakage current supports predictable life planning.
• Clear Leakage Specification: Leakage current bound by the 3√(C·V) µA or 5 mA rule (after 5 minutes at rated voltage) enables accurate thermal and standby current budgeting.
• Regulatory Compliance: RoHS compliance supports deployments in regions requiring lead‑free component selection.
