CMF4-3304HC

Common Mode Chokes Overview

The CMF4-3304HC is a two-line common mode choke manufactured by Gowanda Electronics. It features an inductance of 3.3 mH measured at 10 kHz and supports a maximum current rating of 2.2 A. The component utilizes through-hole termination with a direct current resistance (DCR) of 125 milliohms. This epoxy-potted device is designed for vertical mounting configurations to provide effective electromagnetic interference suppression in demanding electronic circuits.

Common Mode Chokes Feature Summary

• Provides common mode noise filtering for two-line circuits
• Features epoxy potting for environmental protection and mechanical stability
• Designed for vertical printed circuit board mounting

Common Mode Chokes Applications

• Power supply filtering
• Data line protection
• EMI reduction in industrial control systems

Common Mode Chokes Procurement Notes

Verify the specific suffix designation when ordering, as variations such as LF indicate lead-free compliance while other suffixes may denote different mounting orientations or termination styles. Confirm that the required current rating and inductance tolerance align with the system design specifications before procurement to ensure compatibility with the intended application environment.

Common Mode Chokes Selection Notes

Select this component when a robust, vertically mounted common mode choke is required for high-current applications up to 2.2 A. The low DC resistance minimizes power loss, while the epoxy potting ensures durability in harsh environments. Ensure the physical footprint accommodates vertical mounting constraints within the enclosure design.

Common Mode Chokes Part Context

This part belongs to the CMF4 series of broadband power RF transformers and common mode chokes from Gowanda Electronics. The series offers various inductance values and current ratings, catering to aerospace, defense, medical, and industrial sectors.
