LNR1C474MSE

The LNR1C474MSE is a screw-terminal aluminum electrolytic capacitor offering 470,000 µF (470 mF) capacitance at a 16 V rating. Built as a radial can with screw terminals, it delivers high bulk capacitance and secure mechanical connections for general-purpose power applications.

Designed for demanding ripple environments and extended operation, this capacitor combines high ripple-current capability with long endurance at elevated temperature to support robust power-management designs.

Key Features

• Capacitance & Tolerance — 470 mF (470,000 µF) with capacitance tolerance of −20% to +20% (±20% at 120 Hz, 20°C).
• Rated Voltage — 16 V DC rating suitable for low-voltage power rails and bulk storage.
• Construction & Mounting — Radial aluminum can with screw terminals; physical size φ76.2 × 120 mm (φ76.2 × 120L) and nominal bolt diameter M5 for secure bolted connections.
• High Ripple-Current Capability — Low-frequency ripple current 30.5 A at 120 Hz and high-frequency ripple current 35.08 A at 100 kHz to handle heavy AC ripple loads.
• Endurance & Temperature Range — Rated for 5000 hours at 85°C; operating temperature −40°C to +85°C.
• Leakage & Dissipation — Specified leakage current up to 5,000 µA and tangent of loss angle (tanδ) of 1.1 measured at 20°C, 120 Hz.
• Compliance & Packaging — RoHS compliant and supplied in cardboard packing; product is in mass production.

Typical Applications

• General-purpose power systems — Use where large bulk capacitance is required for energy storage and smoothing in DC power rails.
• High-ripple power supplies — Suited to supplies and converters that must tolerate significant AC ripple currents thanks to the 30.5 A (120 Hz) and 35.08 A (100 kHz) ratings.
• Screw-terminal power modules — The screw-terminal radial can and M5-compatible mounting make this capacitor appropriate for assemblies needing robust, bolted electrical connections.

Unique Advantages

• High bulk capacitance in a compact can: 470 mF provides substantial energy storage for smoothing and hold-up in systems where board space is limited.
• Designed for heavy ripple loads: Dual ripple-current ratings (30.5 A @120 Hz and 35.08 A @100 kHz) allow reliable operation in both low- and high-frequency ripple environments.
• Extended endurance at elevated temperature: 5000 hours rated life at 85°C supports long-term reliability in continuous-operation applications.
• Robust screw-terminal mounting: Radial can with screw terminals and M5 bolt compatibility ensures secure electrical and mechanical connection in field-installable modules.
• Measured electrical characteristics: Specified leakage current (5,000 µA) and tanδ (1.1 at 20°C, 120 Hz) provide predictable performance parameters for design verification.
• Production-ready and compliant: RoHS compliant and in mass production, simplifying sourcing and qualification for volume designs.
