LNR1A473MSE

The LNR1A473MSE is an aluminum electrolytic capacitor in Nichicon’s LNR series, configured as a screw-terminal, large-can radial package. It provides 47,000 µF of bulk capacitance at a 10 V rated voltage for general-purpose power applications.

Designed for installations that require high bulk capacitance with secure screw-terminal connections, the LNR1A473MSE combines long-term endurance and measurable ripple handling to support demanding DC power circuits within its specified temperature range.

Key Features

• Capacitance & Voltage: 47 mF (47,000 µF) nominal capacitance at a 10 V rating with a capacitance tolerance of ±20% (measured at 120 Hz, 20°C).
• Ripple Current Capability: Rated ripple current of 6.0 Arms at 85°C (120 Hz) and 6.9 A at 100 kHz, suitable for circuits with sustained AC ripple stress.
• Electrical Losses & Leakage: Specified tangent of loss angle (tan δ) of 0.60 and a measured leakage current of 2.05 mA.
• Temperature & Endurance: Operating temperature range –40°C to +85°C with a rated endurance of 5000 hours at 85°C under DC bias plus rated ripple current.
• Mechanical & Mounting: Screw terminal mounting in a radial, large-can package with body dimensions φ35 × 80 mm (L: 8 × D: 3.5 cm) for secure, high-current connections.
• Polarization & Packaging: Polarized aluminum electrolytic design in a screw-terminal can format for robust panel or chassis mounting.
• Compliance: RoHS compliant.

Typical Applications

• General-purpose power circuits — Provides 47,000 µF bulk capacitance at 10 V for smoothing and energy storage in general-purpose designs.
• Screw-terminal installations — Designed for applications that require secure, bolted electrical connections using screw terminals and a large-can package.
• High-ripple environments — Rated ripple currents of 6.0 Arms (120 Hz) and 6.9 A (100 kHz) make it suitable where sustained AC ripple is present.

Unique Advantages

• Large bulk capacitance: 47,000 µF provides substantial energy storage for DC systems requiring high reservoir capacity.
• Documented ripple performance: Rated ripple current values at both 120 Hz and 100 kHz support predictable thermal and electrical behavior under AC stress.
• Long endurance at rated conditions: 5000 hours at 85°C under DC bias plus rated ripple current demonstrates extended operational life within the specified temperature range.
• Secure mechanical connection: Screw-terminal, radial can package (φ35 × 80 mm) enables reliable bolted connections for high-current applications.
• Wide operating temperature: –40°C to +85°C operating range covers a broad set of general-purpose environments.
• Regulatory compliance: RoHS compliant for use in assemblies requiring restricted-substance conformity.
