LNR1K473MSEN

The LNR1K473MSEN is a screw‑terminal aluminum electrolytic capacitor designed for general‑purpose power applications. It combines high bulk capacitance with an 80 V rated voltage and a rugged screw‑terminal radial can package to support demanding power smoothing and energy‑storage needs.

Engineered for durable performance, this capacitor offers a 5000‑hour endurance at 85°C, measured ripple current capability at both low and high frequencies, and RoHS compliance—making it suitable for production designs that require reliable bulk capacitance and secure electrical connections.

Key Features

• High Capacitance & Voltage 47 mF (47,000 µF) nominal capacitance with an 80 V rated voltage provides substantial bulk energy storage for power supply smoothing and decoupling in general‑purpose systems.
• Electrical Performance Specified tan δ of 0.25 and leakage current listed as 5000 µA support predictable impedance and leakage behavior for system design and power budgeting.
• Ripple Current Capability Rated ripple current of 12.7 A at 120 Hz and 14.61 A at 100 kHz enables handling of both low‑frequency and high‑frequency ripple present in modern power electronics.
• Long Endurance 5000 hours life at 85°C under rated conditions provides long term stability; capacitance and loss characteristics are specified after endurance testing per the series datasheet.
• Wide Operating Temperature Operational range from −40°C to +85°C supports deployment across a broad set of ambient conditions commonly encountered in industrial and general‑purpose equipment.
• Robust Mechanical & Mounting Package Radial can with screw terminals (φ63.5 × 100L) and M5 terminal hardware ensure secure electrical connections and straightforward mechanical retention for panel or chassis mounting.
• Production & Packaging Cardboard packing and mass production status indicate availability and handling suitable for volume manufacturing.
• Environmental Compliance RoHS compliant construction supports regulatory requirements for restricted substances in assemblies.

Typical Applications

• General‑purpose power supplies — Bulk energy storage and smoothing where high capacitance and an 80 V rating are required to stabilize DC rails and absorb ripple.
• Industrial equipment — Provides durable bulk capacitance for control cabinets and power modules operating in environments within −40°C to +85°C.
• Power conditioning and filtering — Handles significant low‑ and high‑frequency ripple with rated ripple current specs at 120 Hz and 100 kHz.
• Backup and hold‑up circuits — Large capacitance supports short‑term energy hold‑up and ride‑through functions in general‑purpose systems.

Unique Advantages

• Significant bulk capacitance in a single component: 47,000 µF provides large energy storage density to reduce the number of parallel parts and simplify BOM.
• High ripple handling across frequencies: Rated ripple currents at 120 Hz and 100 kHz give clear design data for both low‑ and high‑frequency stress cases.
• Screw‑terminal reliability: Robust screw terminals (M5) and a radial can form factor enable secure, low‑impedance connections for chassis or bracket mounting.
• Long specified life at elevated temperature: 5000 hours at 85°C offers predictable aging behavior for designs requiring extended field life.
• Design‑friendly electrical limits: Specified tan δ, leakage current, and ±20% capacitance tolerance provide measurable parameters for system modeling and verification.
• Regulatory compatibility: RoHS compliance helps streamline integration into assemblies that must meet restricted‑substance requirements.
