LNR1H473MSEB

The LNR1H473MSEB is a screw‑terminal aluminum electrolytic capacitor designed for high-capacitance DC energy storage and power‑filtering applications. It provides 47,000 µF at a 50 V rating in a radial can with screw terminals, offering a compact, serviceable form factor for industrial and power-electronics systems.

Engineered for general-purpose power systems, the capacitor combines high bulk capacitance, robust screw-terminal mounting and an −40 °C to +85 °C operating range with a rated endurance of 5,000 hours at 85 °C, supporting reliable performance in demanding environments.

Key Features

• High Capacitance & Voltage 47,000 µF nominal capacitance at 50 V provides substantial bulk energy storage for smoothing and decoupling in DC power rails.
• Package & Mounting Radial can with screw terminals (φ51 body) for secure mechanical and electrical connections; terminal hardware compatible with M5 nominal bolt size for φ51 types as specified in the series documentation.
• Operating Temperature & Lifetime Rated for −40 °C to +85 °C operation with an endurance specification of 5,000 hours at 85 °C under rated ripple and DC bias conditions.
• Ripple Current Performance Rated ripple current of 8.6 A at 120 Hz and 9.89 A at 100 kHz, suitable for applications with significant AC components on DC lines.
• Electrical Characteristics Polarized design with ±20% capacitance tolerance (at 120 Hz, 20 °C) and leakage current limited by the standard series specification (after 5 minutes: ≤ 3√CV µA or 5 mA, whichever is smaller, at 20 °C).
• Mechanical Size Cylinder dimensions: diameter 5.1 cm × length 9 cm (φ51 × 90 mm), supplied in cardboard packing for mass production handling.

Typical Applications

• Power Supply Filtering: Bulk smoothing and energy buffering on 50 V DC rails to reduce ripple and stabilize downstream converters.
• DC Bus Energy Storage: Local energy reservoir for inverters, motor drives or power converters where high-capacitance, low-impedance storage is required.
• Industrial & UPS Systems: Energy hold-up and surge absorption in industrial power subsystems and uninterruptible power supplies with screw-terminal mounting for easy serviceability.

Unique Advantages

• Substantial Bulk Storage: 47,000 µF at 50 V delivers high energy density for minimizing voltage sag and providing hold-up energy in DC systems.
• Robust Screw-Terminal Connections: Screw terminal construction with M5-compatible hardware (φ51 size) ensures secure, low-resistance connections for high-current applications.
• Designed for High Ripple Loads: Specified ripple current values at 120 Hz and 100 kHz indicate suitability for power electronics with both low- and high-frequency ripple components.
• Tolerant Thermal Range and Proven Endurance: −40 °C to +85 °C operating range and 5,000-hour endurance at 85 °C provide predictable aging and performance over time.
• Clear Electrical Limits: Leakage current governed by the series standard (≤ 3√CV µA or 5 mA after 5 minutes at 20 °C) supports predictable power‑loss budgeting in designs.
