AML0618-4R4M7R2-S1

Overview

The TDK AML0618-4R4M7R2-S1 is a two-line through-hole common mode choke coil designed for electromagnetic interference suppression. It features a ferrite rod core with high-saturation magnetic flux density, enabling a compact radial horizontal cylinder package measuring 6.00mm in diameter and 17.50mm in length. The component supports a maximum rated current of 4.4A and maintains a low DC resistance of 14mΩ. It operates within a temperature range of -40°C to +125°C and holds AEC-Q200 automotive qualification.

Feature Summary

• Utilizes a ferrite rod core design to achieve high saturation magnetic flux density for effective noise suppression in a miniaturized form factor.

Applications

• Public information-processing equipment
• Automotive electronic systems requiring AEC-Q200 compliance

Procurement Notes

Verify the specific ordering suffix to ensure correct electrical characteristics and packaging configuration. Confirm that the component meets the required AEC-Q200 reliability standards for your target application. Check the manufacturer's lifecycle status, as this part may be subject to change or obsolescence notices. Ensure the through-hole mounting type aligns with your PCB layout constraints.

Selection Notes

Select this component when a robust, high-current common mode choke is needed for automotive or industrial applications. The 4.4A rating and low DCR make it suitable for power line filtering where minimal voltage drop is critical. The radial horizontal package facilitates easy insertion into standard through-hole assembly processes. Consider the physical dimensions to ensure adequate clearance on the printed circuit board.

Part Context

This component belongs to the TDK AML series of common mode chokes, which are characterized by their rod core construction and high saturation capabilities. The series offers various current ratings and impedance values to suit different filtering requirements. The AML0618 variant specifically denotes the physical size code within the product family, indicating its compact footprint relative to other series members.

Replacement Considerations

Consult the official TDK distribution documents for potential substitute part numbers. Verify compatibility regarding pinout, physical dimensions, and electrical specifications before replacing the original component.
