Electromagnetic interference elimination solutions: EMI filters
Concurrent with the rapid growth of devices that utilize digital techniques, the problems of Electro-Magnetic interference (EMI) are becoming more severe. Electromagnetic interference filters, popularly called as EMI filters, are just what you need to reduce interference generated by the device or by other devices present near for a clearer signal.
Our partners for EMI filters are leading global suppliers Delta Electronics and Enjoye Electronic. They offer EMI filters with varied voltage range, single phase 115/250 V, 3 Phase 520 V and up to 600 A maximum rated current. Different kinds of connection are also available. Our EMI filter can solve the EMC problem effectively, shorten the design cycle time and provide reliable EMC solutions.
You can read more about what EMI filters are and how they work in the news item EMI filters for high-reliability applications.
How to choose the right EMI filter?
(for designers of electrical or electronic devices)
When choosing EMI filters, we decide based on several parameters:
Housing size
Insulation resistance
I/0 connectors
Breakthrough voltage
Mounting method
Pulse or peak attenuation at high voltage
Compliance with international safety standards
Operating temperature
Nominal voltage
One-way resistance
Nominal current
Loss
Leakage current
Leakage current and breakdown voltage are important parameters for medical filters.
