EMI Filters

DC/DC front-end filters feature active surge protection or EMI filter. The filter module is able to protect the DC/DC converter which is connected behind the filter module and streamline the power stage development with the shortest duration.

• What is the purpose of the EMI filter?

An EMI filter incorporates capacitors and inductors that could mitigate conducted or radiated electromagnetic interference from electronic devices to others.

• Where is EMI filter connected?

Normally, an EMI filter is connected to input terminals. There may be a few capacitors that are recommended to connect between input and output.

• When do I need to use a EMI Filter?

Electromagnetic interference always comes from electronic devices. Every electronic device should install an EMI filter in order to mitigate interference to other devices as well as comply with corresponding regulations.
