The main job of an EMI Low Pass Filter is to protect against “RF leakage,” as the desired signal passes into or out of an enclosed system. EMI Low Pass Filters are used in many circuit-level and system-level RF applications, such as Test & Measurement (lab or factory), amplifiers, transmitters and receivers. Discrete EMI Filters can be incorporated into connectors for filter arrays as an integrated solution.
Richardson RFPD carries a full line of EMI Low Pass Filters which offer effective filtering through 18 GHz. These capacitive-based filters are available in surface mount or feed-thru mounting styles and several circuit configurations, including C, L, Pi, T and Double-T filters. Performance grades are available from low-cost commercial to rugged military.
Specific attributes which are important in selecting the right EMI Low Pass Filters for your application include the attributes “Type” (C, Double-T, Feed Thru, Filter Plate, Hermetically-Sealed, L, LC, Pi, Resin-Sealed) and “Package Type” (Bolt-In, Solder-In, Surface Mount, Panel-Mount, Press-In, Threaded Case, Terminal Block, and Snap-In).
Richardson RFPD provides hundreds of different EMI Low Pass Filters from industry-leading manufacturer Spectrum Advanced Specialty Products. Although many standard variations are available in stock, custom solutions can be developed upon request.Contact your local sales representative to explore a custom solution.
The parametric search filter allows the user to quickly find the parts they need by filtering the results in real-time.
Additionally, some attributes allow for the conversion of their base type to different types. For example, the attribute group for minimum frequency is shown in MHz. The values can be converted to be shown in KHz or GHz by selecting the conversion type from the ‘Select Conversion’ drop down list.
Any Attribute that does not interest the user can be hidden by clicking on the ‘X” in the upper-right corner of the attribute. To show any hidden attributes, simply click the ‘Unhide Attributes’ button in the bottom of the parametric search filter.
If you are experiencing performance issues, please use a newer browser such as Chrome or Firefox, or disable the ability of the filter to perform dynamic updates by deselecting the checkbox titled ‘Allow Filters to Dynamically Update Parametric Search Attributes’.
