ED101-0.2-40M

Overview

The ED101-0.2-40M is a two-line common mode choke manufactured by Schaffner EMC Inc., designed for power line filtering applications. It features a nominal inductance of 40 mH at 10 kHz and supports a maximum current rating of 200 mA. The component utilizes through-hole mounting with a typical DC resistance of 10 Ohms. It is engineered to suppress electromagnetic interference (EMI) within electronic circuits, providing effective noise reduction for sensitive equipment.

Feature Summary

• Provides effective suppression of electromagnetic interference (EMI) in power line applications
• Designed specifically for two-line common mode noise reduction
• Utilizes through-hole mounting technology for secure PCB integration

Applications

• Power supplies
• Battery chargers
• Portable devices
• Energy-efficient systems

Procurement Notes

Verify the manufacturer designation carefully, as this component is associated with both Schaffner EMC Inc. and TE Connectivity due to corporate acquisitions. Confirm that the specific part number matches the required electrical specifications, particularly the 40 mH inductance and 200 mA current rating, before finalizing procurement orders to ensure compatibility with existing circuit designs.

Selection Notes

Select this component when designing circuits requiring robust EMI suppression for low-current applications up to 200 mA. The 40 mH inductance value is suitable for filtering frequencies around 10 kHz. Ensure the PCB layout accommodates the through-hole mounting style and provides sufficient clearance for the physical dimensions of the choke to maintain safety standards and thermal performance.

Part Context

This component belongs to the common mode choke category, which is essential for maintaining signal integrity and compliance with electromagnetic compatibility regulations. Common mode chokes are widely used in consumer electronics and industrial equipment to mitigate conducted emissions. The ED101 series represents a standard solution for general-purpose power line filtering where space and cost efficiency are balanced with performance requirements.

Replacement Considerations

The ED100-0.2-40M is identified as a similar product within the same manufacturer's portfolio. Verify if the ED100 variant offers identical electrical characteristics or any specific improvements in packaging or tolerance before considering it as a substitute.
