EMI/RFI Filters (LC, RC Networks)

Products in this family integrate several passive components into a single device in a manner designed to yield a frequency dependent opposition to current flow. Though other types are available, a majority of them are of a low-pass type used to suppress the unwanted transmission of high frequency signals, which might otherwise cause interference or undesired operation.
