LNR2E472MSE

The LNR2E472MSE is a screw‑terminal aluminum electrolytic capacitor rated 4700 µF at 250 V, designed for general‑purpose power filtering and energy storage in industrial and power electronics systems. It delivers high ripple handling and long endurance in a radial can package with screw terminals, suitable for systems that require robust bulk capacitance and secure mechanical mounting.

Key value comes from its combination of high capacitance, high voltage rating, and rated endurance of 5000 hours at 85°C, providing predictable performance for designs that must manage significant ripple currents and DC bias.

Key Features

• Capacitance and Voltage: 4700 µF nominal capacitance with a 250 V rated voltage, offering substantial bulk energy storage for high‑voltage power rails.
• Capacitance Tolerance: ±20% at 120 Hz, 20°C, enabling designers to account for expected variation in system capacitance.
• Screw‑Terminal Mounting: Radial can with screw terminals (φ63.5 body), providing secure electrical and mechanical connections for high‑current assemblies; nominal bolt size for φ63.5 parts is M5.
• High Ripple Current Capability: Low‑frequency ripple current 7.3 A (120 Hz) and high‑frequency ripple current 8.76 A (100 kHz), supporting demanding filtering and decoupling duties under AC ripple load.
• Leakage and Dissipation: Specified leakage current 3250 µA and tanδ (DF) 0.2 measured at 20°C, 120 Hz, for predictable loss and self‑heating characteristics.
• Endurance and Temperature Range: Rated endurance 5000 hours at 85°C with an operating temperature range of −25°C to +85°C for the 160–250 V class, providing longevity in elevated temperature environments.
• Form Factor and Packaging: Body size φ63.5 × 100L (L: 10 × D: 6.35 cm) in a radial can with standard 3‑leg mounting bracket; shipped in cardboard packing for handling and storage.
• RoHS Compliant: Conforms to RoHS requirements as stated in the product data.

Typical Applications

• Power Supply Bulk Filtering: Smooths DC output and absorbs ripple in high‑voltage SMPS and industrial power supplies where high capacitance and ripple handling are required.
• Energy Storage for Power Converters: Provides bulk energy for DC bus stabilization and transient support in motor drives and converter stages.
• UPS and Backup Systems: Used for bulk charge storage and smoothing in uninterruptible power supplies and battery‑assist circuits operating at elevated voltages.
• Industrial Electronics: Suited to control cabinets and power distribution modules that require secure screw‑terminal connections and robust lifetime at higher ambient temperatures.

Unique Advantages

• High Bulk Capacitance at 250 V: 4700 µF provides substantial energy storage in a single component, reducing the number of parallel devices needed.
• Robust Ripple Performance: Specified ripple currents at both low and high frequencies enable predictable thermal and electrical behavior under AC stress.
• Long Endurance at Elevated Temperature: 5000 hours at 85°C gives designers a clear reliability target for long‑term applications.
• Secure Mechanical and Electrical Termination: Screw terminals and standard 3‑leg bracket for φ63.5 ensure strong mounting and low‑resistance connections in high‑current assemblies.
• Measurable Loss Characteristics: Provided tanδ and leakage current figures allow accurate thermal and leakage budgeting in power system designs.
• Compliance and Handling: RoHS compliance and cardboard packing support environmental requirements and practical handling during assembly and storage.
