LNR1C474MSEB

The LNR1C474MSEB is a screw-terminal aluminum electrolytic capacitor from Nichicon's LNR series, designed for general-purpose applications requiring very large capacitance and robust ripple handling. Its radial can with screw terminals and high-capacitance construction provide bulk energy storage and smoothing in power systems that require reliable DC filtering.

Key electrical characteristics include 470,000 µF capacitance at 16 V, ±20% tolerance, high low- and high-frequency ripple current capability, and a rated operating range of −40°C to 85°C with a 5,000-hour endurance at 85°C. This part is RoHS compliant and available in mass production.

Key Features

• High Capacitance — 470,000 µF (470 mF) nominal capacitance for substantial bulk energy storage and smoothing.
• Rated Voltage — 16 V DC rating suitable for many low-voltage power systems.
• Tolerance — ±20% capacitance tolerance at 120 Hz, 20°C for predictable performance in filter and hold-up applications.
• High Ripple Current Handling — 30.5 A at 120 Hz (low frequency) and 35.08 A at 100 kHz (high frequency) for demanding ripple and transient environments.
• Electrical Loss and Leakage — tan δ = 1.1 (measurement conditions per datasheet) and leakage current specified at 5000 µA, enabling predictable dissipation and standby characteristics.
• Endurance & Temperature Range — Rated for 5,000 hours at 85°C; operating temperature range −40°C to 85°C per series specifications.
• Robust Mechanical Package — Radial can with screw terminals (φ76.2 mm × 120 mm length) and standard mounting bracket options for secure installation.
• Regulatory Compliance — RoHS compliant.

Typical Applications

• Power Supply Smoothing — Large capacitance and high ripple current ratings support bulk smoothing and energy buffering in general-purpose power supplies.
• Backup and Hold‑up Energy Storage — High µF value provides extended hold-up capacity for short-term power backup and energy release during transients.
• Industrial Power Systems — Screw-terminal mounting and robust mechanical package enable secure connections in equipment and system-level power assemblies.
• High-Current Filtering — Elevated low- and high-frequency ripple current capability supports filtering in designs with substantial AC ripple or switching noise.

Unique Advantages

• Substantial Energy Density — 470,000 µF nominal capacitance reduces the number of components required for bulk storage compared to lower-capacitance solutions.
• Designed for High Ripple — Specified 30.5 A (120 Hz) and 35.08 A (100 kHz) ripple currents directly address applications with significant AC content or switching transients.
• Long Endurance at Elevated Temperature — 5,000-hour rating at 85°C provides a measurable lifecycle expectation for thermal-stressed deployments.
• Screw-Terminal Reliability — Screw terminal terminations and available bracket mounting simplify high-current connections and mechanical fastening in assemblies.
• Predictable Electrical Behavior — Specified tan δ and leakage parameters allow designers to estimate dissipation and standby leakage for system-level power budgeting.
• RoHS Compliant and Production-Ready — Meets RoHS requirements and is available in mass production for immediate design integration and procurement.
