The LNR2C473MSEB from Nichicon is a screw‑terminal aluminum electrolytic capacitor offering 47,000 µF capacitance at a 160 V rating. It is a high‑capacity, polarized radial can designed for general‑purpose power applications that require substantial bulk energy storage and robust ripple handling.

Built on the LNR series platform, this component delivers high ripple current capability and long endurance for sustained operation at elevated temperatures, making it suitable for demanding industrial and power electronics environments where secure screw‑terminal connections are required.

Key Features

• Capacitance: 47 mF (47,000 µF) nominal capacitance for significant bulk energy storage and smoothing.
• Rated Voltage: 160 V DC rated voltage appropriate for higher‑voltage power rails.
• Tolerance & Polarization: ±20% capacitance tolerance; polarized design for DC applications.
• High Ripple Current: 20.6 A at 120 Hz (low frequency) and 24.72 A at 100 kHz (high frequency), supporting heavy AC ripple and transient loads.
• Leakage Current: Specified leakage current of 5,000 µA at initial condition.
• Endurance & Reliability: Rated for 5,000 hours at 85 °C; LNR series endurance specifies capacitance change within ±15% and leakage current within initial specified value after test conditions.
• Operating Temperature: –25 °C to +85 °C (series category temperature range for 160–250 V).
• Mechanical & Mounting: Radial can with screw terminals for secure high‑current connections; physical size φ90 × 170L (approx. 17.0 × 9.0 cm).
• Packaging & Status: Cardboard packing; mass production status.
• Compliance: RoHS‑compliant.

Typical Applications

• Power supply bulk filtering: Large capacitance and high ripple current allow effective smoothing of DC rails and reduction of voltage ripple under heavy loads.
• Industrial power systems: Suitable where sustained ripple currents and long endurance at elevated temperatures are required for reliable operation.
• Inverter/DC‑link and motor drive systems: High capacitance at 160 V and screw‑terminal mounting support energy buffering and high‑current connections in power conversion circuits.
• Uninterruptible power and backup systems: Provides bulk energy storage and transient support for short‑term hold‑up and load stabilization.

Unique Advantages

• High bulk energy capacity: 47,000 µF at 160 V delivers substantial stored charge for smoothing and hold‑up functions, reducing the need for multiple smaller capacitors.
• Robust ripple performance: Rated for 20.6 A at 120 Hz and 24.72 A at 100 kHz to handle both low‑ and high‑frequency ripple components.
• Durable endurance profile: 5,000 hours at 85 °C with defined post‑test limits for capacitance and leakage current, supporting long service life in elevated‑temperature environments.
• Screw‑terminal mounting: Provides secure, low‑resistance connections for high‑current systems and simplifies installation and maintenance.
• Proven series and manufacturer: Part of Nichicon’s LNR series, with series‑level specifications for stability and shelf‑life that support predictable design margining.
• Regulatory compliance: RoHS‑compliant for use in environments requiring restricted‑substance conformance.
