MM1400-200

The MM1400-200 is a ferrite EMI Disk suitable for radiated and inductively-coupled electromagnetic interference. After the PC board soldering process a ferrite disk or plate can be installed directly on the source of EMI. Each part for volume production is provided with permanent, double sided 3.5 mil acrylic adhesive with 218oz./inch2 adhesion. The ferrite disk can be utilized either as inductively coupled components or EMI shields on PC board components and traces. Inductive coupling occurs when the ferrite affects the conducted wave form leaving the active component. The rise time of the wave form is effectively slowed by the ferrite and the overshoot and associated ringing are attenuated. EMI shielding occurs when the ferrite absorbs the radiated emissions from active components, effectively protecting other boards or components in the vicinity from radiated contamination. It can be used to locate unwanted EMI antennas, can also provide retrofit and auxiliary EMI attenuation.
