Emi Filters
What is an EMI Filter?
An EMI filter, or electromagnetic interference filter, is an electronic passive device which is used to suppress conducted interference that is present on a signal or power line. EMI filters can be used to suppress interference that is generated by the device or by other equipment in order make a device more immune to electromagnetic interference signals present in the environment. Most EMI filters consist of components that suppress differential and common mode interference.
Types of EMI Filters
There are many different kinds of EMI filters. At Future Electronics, we stock many of the most common types categorized by type, case size / dimension, impedance, maximum DC resistance, capacitance and rated current. The parametric filters on our website can help refine your search results depending on the required specifications.
The most common values for capacitance are 100 pF, 470 pF, 1 nF, 2.2 nF and 22 nF. We also carry EMI filters with capacitance up to 27 µF. Rated current can have a range between 1 mA and 100 A, with the most common EMI filters having a rated current of 200 mA, 300 mA, 2A or 6 A.
