Electromagnetic interference degrades electronic performance and causes unintended outcomes like signal distortion, data corruption and system malfunctions. To minimize interference, Knowles Precision Devices has expanded EMI filter offerings to include hermetically sealed EMI filters that attenuate unwanted EMI signals while allowing desired signals to pass. SFSW series filters were designed to preserve signal integrity and ensure reliable operation in high-reliability applications with strict electromagnetic compatibility standards.

Here's what you can expect from our SFSW series:

When it comes to aerospace and defense applications, every single component plays a role in the success and longevity of the system. Capacitors are vital in flight control systems, radar systems, signal intelligence equipment and more. They support functions across guidance and control systems, electronic warfare (EW) and power supply units. To best support these development projects, Knowles sought MIL-PRF-55681 qualification for ten capacitor styles we manufacture and test in the United States. With this qualification, you can be assured that you’re using robust and dependable ceramic capacitors in your mission-critical systems.
