Snubber capacitors protect EV power electronics from voltage spikes generated during high-frequency switching.

To help customers with filter selection, we generally provide a lot of information on what our filters can do. But in this new Filter Basics Series, we are taking a step back to cover some background information on how filters do what they do.

In this new application note, we dive into the details on all things related to tuning elements.

Learn how waveguides, transmission lines, and electromagnetic modes influence RF filter design.

When selecting a filter implementation, one factor that is common across all frequencies is optimizing the size of the filter given the application and the required performance.

Surface-mount EMI filters provide high-performance noise suppression for demanding, high-reliability applications.

Understanding lumped and distributed element filter construction helps engineers choose the right approach based on frequency, performance, size, and application needs.

SiC converters deliver higher voltage and efficiency than silicon, with snubber circuits and capacitors further improving performance.

Non-magnetic components help MRI machines produce clear, reliable images by preventing interference with the powerful magnetic field.

As high-performance capacitors take on more demanding applications, manufacturers must also consider whether international trade regulations apply.

Understanding filter types and technologies helps engineers select the right filtering solution for their frequency, bandwidth, performance, and application requirements.

At very high frequencies, careful circuit board design is essential to keeping RF filters and communication systems performing their best.
