FN 409 PCB filters are designed to surpress common and differential-mode noise on DC voltage lines. The suppression performance is special designed to fulfill the requirements for high frequency switching DC/ DC converter modules. FN 409 filters can also be used to filter the output current of switch-mode power supplies in applications with intelligent power distribution.

Features and benefits:

• High common and differential-mode noise suppression.
• Rated currents up to 13A at 75VDC.
• Small form factor.
• Good thermal conductance.

Typical applications:

Input or output filter for high frequency DC/DC converters
DC output filter for switch-mode power supplies
Computer and office automation equipment
Telecom equipment
Input/output filter within DC power distribution networks
