    Premier Magnetics’ New Chokes Offer Integrated Magnetics and Innovative Mounting

    03/26/2025

    ­Premier Magnetics, global producer of high-quality magnetic components for a wide range of power conversion and communications applications, introduces the PM-CMCX5 Series, the first offering in the company’s new CM Guard Series™ of advanced-technology chokes. The CM Guard Series implements integrated magnetics technology to build common mode (CM) and differential mode (DM) attenuation into a single device. The PM-CMCX5 Series devices’ performance features include strong winding-to-winding insulation (5KV), wide operating temperature (-60°C to 155°C) and low-capacitive coupling to the core. Excellent mechanical stability is achieved utilizing Premier Magnetics’ proprietary Snap-In Technology to secure parts to the pc board without the use of epoxy during the assembly process.

    The new PM-CMCX5 Series offers sixteen models with a selection of spread or compressed windings and common mode choke inductances from 0.5 to 30mH. The data sheet includes a part-number chart providing details on differential mode inductances, typical current to cause a temperature rise of 70°C (IDC), DC resistance (DCR), and self-resonant frequency (SRF).

    “Our new highly integrated, high-performance CM Guard Series provides common mode and differential mode attenuation in a single device. They can serve to reduce the number of components in a filter assembly,” said Premier Magnetics president, Dennis Earley. “Using our unique Snap-In Technology, they also simplify and speed up product assembly by eliminating time-consuming epoxy application.” Earley added, “Over the coming year we’ll expand the CM Guard Series portfolio to provide models with higher DM inductance, higher temperature stability and reduced size”
