CMF4-2503H

Common Mode Chokes Overview

The Gowanda CMF4-2503H is a radial lead common mode choke designed for power line applications. It provides 250 µH inductance at 10 kHz with a maximum current rating of 12A and a maximum DC resistance of 3.8 mOhm. The component features a horizontal cylinder open package suitable for through-hole mounting and operates within a temperature range of -55°C to 125°C.

Common Mode Chokes Feature Summary

• Engineered to effectively suppress electromagnetic interference by filtering out common mode noise from power lines.
• Features a robust horizontal cylinder open package configuration designed for reliable through-hole mounting.

Common Mode Chokes Applications

• Power line EMI suppression
• Electromagnetic interference filtering
• Common mode noise reduction

Common Mode Chokes Procurement Notes

Verify the specific termination style required, as ordering suffixes such as LF indicate RoHS compliance. Confirm that the horizontal cylinder open package aligns with your PCB layout constraints. Ensure the 12A current rating and 3.8 mOhm DCR meet your circuit's thermal and electrical requirements before finalizing procurement.

Common Mode Chokes Selection Notes

Select this component when high current handling up to 12A is required alongside significant common mode attenuation. The low DC resistance minimizes power loss in high-current paths. Consider the radial horizontal form factor for space-constrained through-hole designs where vertical clearance is limited but board area allows for lateral component placement.

Common Mode Chokes Part Context

This part belongs to the CMF4H series of radial lead common mode chokes manufactured by Gowanda Electronics. The series is characterized by its ability to handle substantial currents while providing effective EMI suppression. These components are typically utilized in environments requiring robust filtering solutions for power integrity.
