  • Electronic Impedance Matching and Maximum Power Transformers
    High Frequency Matching Transformer for Switching Power Supplies

    High Frequency Electronic Matching Transformers are intended for measuring electric signal voltages or currents which contain useful data. They match the signal source with the load ensuring the minimum signal distortion. Along with active components (such as transistors and lamps) they are included into devices amplifying electric oscillations that work within a wide frequency band.

Common Mode Power Line Chokes for PCB Mounting
