The purpose of the toroidal inductor is for use in a new high frequency brain scanning system, a type of Magnetoencephalography (MEG) brain scanning system. Most common mode chokes on need to operate at frequencies below 250 kHz. The client’s requirement was highly unusual in that the component is required to operate at frequencies approaching 500 MHz.
CET Technology achieved the required high frequency performance through the selection of a unique core construction with a novel winding method to meet customer’s specifications. The CET components reduced unwanted electrical noise within the system by greater than 20dB. The results of all this, it is expected, are enhanced brain scan images that are detailed enough to find even minor injuries such as concussions due to sports injuries.
