LNR1C473MSEN

The LNR1C473MSEN is a screw-terminal aluminum electrolytic capacitor offering 47,000 µF capacitance at a 16 V rating in a φ35 × 80 mm can. Designed for general-purpose power applications, it delivers large bulk energy storage with polarized screw-terminal connections for robust electrical and mechanical mounting.

Key value comes from high ripple-current capability, long endurance at elevated temperature, and a compact radial can package that supports reliable power smoothing and energy-hold functions in equipment that requires substantial capacitance and sustained performance.

Key Features

• Large Capacitance & Voltage: 47,000 µF nominal capacitance at 16 V with ±20% tolerance, providing significant bulk energy storage for DC smoothing and hold-up.
• High Ripple-Current Handling: 6.4 A at 120 Hz (low frequency) and 7.36 A at 100 kHz (high frequency) rated ripple currents to support heavy AC ripple conditions and switching power stages.
• Endurance & Temperature Range: Rated for 5,000 hours at 85°C with operating range −40°C to +85°C, enabling sustained performance under elevated temperature stress.
• Leakage & Loss Characteristics: Specified leakage current of 2,600 µA and tangent of loss angle (tan δ) of 0.4 at 20°C, 120 Hz, for predictable DC leakage and dissipation behavior.
• Screw Terminal Mounting: Radial can with screw terminals for secure electrical connections and easy integration into chassis or bracket-mounted power assemblies.
• Packaging & Production Status: Supplied in cardboard packing and available in mass production for volume designs.

Typical Applications

• General-purpose power filtering: Bulk energy storage and smoothing in power supplies where large capacitance and high ripple-current capability are required.
• DC bus and hold-up circuits: Energy hold and transient support in systems that need substantial stored charge at low voltage.
• Power conditioning for industrial equipment: Use in assemblies that require screw-terminal mounting and robust ripple handling for continuous operation at elevated temperatures.

Unique Advantages

• Exceptional bulk capacitance: 47,000 µF provides ample charge storage to reduce voltage ripple and extend hold-up time without increasing stack complexity.
• Dual-frequency ripple capability: Rated ripple currents at both 120 Hz and 100 kHz ensure performance across legacy line-frequency and modern switching environments.
• Long endurance at 85°C: 5,000-hour lifetime rating supports designs that must maintain capacitance, dissipation factor, and leakage over prolonged elevated-temperature exposure.
• Screw-terminal robustness: Provides a secure, low-resistance electrical connection suitable for high-current paths and straightforward mechanical mounting.
• Predictable electrical behavior: Specified tan δ and leakage current figures enable accurate thermal and leakage budgeting in power designs.
