LNR1A474MSEB

The LNR1A474MSEB is a screw-terminal aluminum electrolytic capacitor designed for general-purpose power applications requiring very large bulk capacitance. It is a radial, can-style screw terminal device with a rated capacitance of 470000 µF (470 mF) at 10 V and an 85°C category temperature rating.

Engineered for high ripple environments and long endurance, this capacitor combines high capacitance, substantial ripple-current capability, and a 5000-hour life at 85°C to support demanding power-conditioning and energy-storage roles in industrial and commercial equipment.

Key Features

• High Capacitance: 470000 µF (470 mF) nominal capacitance for substantial bulk energy storage and smoothing in DC power systems.
• Rated Voltage: 10 V DC rated voltage suitable for low-voltage power rails and storage applications.
• High Ripple Current Capability: Low-frequency ripple current of 19.0 A (120 Hz) and high-frequency ripple current of 21.85 A (100 kHz), enabling reliable operation under continuous ripple stress.
• Endurance and Reliability: Rated for 5000 hours at 85°C under D.C. bias plus rated ripple current, with defined limits for capacitance change, tan δ, and leakage current after endurance testing.
• Loss Characteristics: Specified tangent of loss angle (tan δ) of 1.2 measured at 20°C and 120 Hz to characterize dissipation behavior.
• Leakage Current: Specified leakage current up to 5000 µA following rated voltage application conditions.
• Robust Mechanical Package: Radial can with screw terminals and a physical size of φ63.5 × 120 mm, supplied in cardboard packing for handling and storage.
• Operating Range and Compliance: Rated operating temperature range of −40°C to +85°C and RoHS compliant.

Typical Applications

• General-purpose power supplies: Bulk energy storage and smoothing on low-voltage DC rails where large capacitance and high ripple capability are required.
• Power-conditioning modules: Filtering and stabilization in systems that experience substantial AC ripple or high-frequency switching currents.
• Industrial equipment: Energy buffering and decoupling in industrial power assemblies that need long endurance at elevated temperatures.

Unique Advantages

• Exceptional bulk storage: 470000 µF nominal capacitance provides large charge capacity to reduce voltage sag in power subsystems.
• High ripple tolerance: Specified ripple currents of 19.0 A (120 Hz) and 21.85 A (100 kHz) support sustained operation under heavy ripple loading.
• Long-rated life at elevated temperature: 5000-hour endurance at 85°C underrated conditions gives predictable performance for long deployments.
• Secure screw-terminal mounting: Screw terminals and a robust radial-can package simplify mechanical integration and high-current connections.
• Measured dissipation and leakage data: Clear tan δ (1.2 at 20°C, 120 Hz) and leakage current limits allow designers to quantify losses and stand-by drain.
• Regulatory compliance and supply status: RoHS compliant and in mass production for reliable sourcing.
