LNR1C474MSEN

The LNR1C474MSEN is a screw‑terminal aluminum electrolytic capacitor from Nichicon’s LNR series, engineered for high-capacitance, general-purpose power applications. It delivers 470,000 µF (470 mF) at 16 V in a robust radial can with screw terminals, intended for systems that require large energy storage and high ripple handling in a compact cylindrical package (φ76.2 × 120 mm).

Designed for continuous operation up to 85°C and rated for 5,000 hours at that temperature, this capacitor targets industrial and power-electronics applications where long endurance, high ripple current capability, and straightforward screw‑terminal mounting are important.

Key Features

• High capacitance and rated voltage — 470,000 µF capacitance at 16 V provides substantial energy storage for bulk filtering, hold‑up and smoothing applications.
• High ripple current capability — 30.5 A at 120 Hz (low frequency) and 35.08 A at 100 kHz (high frequency) to support heavy AC ripple conditions in power supplies and converters.
• Endurance and temperature rating — 5,000 hours rated life at 85°C with operating temperature range −40°C to +85°C, supporting long service life in elevated-temperature environments.
• Loss characteristics — tan δ (DF) 1.1 measured at 20°C, 120 Hz, with capacitance tolerance ±20%, enabling predictable impedance and loss behavior in design.
• Leakage current — specified leakage current of 5,000 µA, provided for conservative sizing of discharge and bleeder circuits.
• Mechanical and mounting — radial can with screw terminals and M5 bolt accommodation (φ76.2 body), suitable for secure, low-inductance connections in power racks and assemblies.
• Compliance and packaging — RoHS compliant and shipped in cardboard packing; product is in mass production.

Typical Applications

• Power supply bulk filtering — Large capacitance and high ripple current ratings make this capacitor suitable for DC bus smoothing and bulk energy storage in industrial power supplies.
• UPS and hold‑up circuits — The high capacitance and long endurance at 85°C support energy hold‑up requirements for backup and ride‑through systems.
• Motor drives and inverters — Robust screw‑terminal mounting and high ripple capability enable use in inverter DC link and drive power electronics.

Unique Advantages

• Substantial energy density: 470,000 µF at 16 V provides significant bulk storage in a single component, reducing the number of parallel devices required.
• High ripple handling: Rated for 30.5 A (120 Hz) and 35.08 A (100 kHz), enabling reliable operation under heavy AC ripple and switching conditions.
• Long operational life: 5,000 hours at 85°C supports extended maintenance intervals and predictable end-of-life behavior for industrial installations.
• Robust screw‑terminal packaging: M5-compatible screw terminals and radial can construction allow secure, low-resistance connections for high-current applications.
• Known loss and leakage parameters: Specified tan δ and leakage current values make it straightforward to model thermal and discharge behavior in system design.
• Regulatory compliance: RoHS compliant to meet environmental requirements for electronic assemblies.
