For telecommunications, the device is well suited to filter narrowband signals, DSL baluns, for GbE and 100 Gbps systems. Additionally, it is well suited to fibre coaxial .RF applications and is suited for use with both coaxial and twisted pair cable.

The SRF1280-330M is also well suited for automotive and home appliances. In the automotive sector, it can be used for DC-DC converters, EMC/EMI filters, and for other automotive applications. For home appliance applications, it is ideal for use in medical products, home theatre systems, and more.

Working Principle

The SRF1280-330M is designed around two planar transformer coils and a low noise EMI filter to provide distinctive broadband performance. The device uses two planar transformer coils to convert between two electrical or physical states. Each coil includes a ferrite core and copper wound primary and secondaries. The coils are designed to provide a reliable transmission of electrical/magnetic signals with excellent uniformity.

The low noise EMI filter functions by applying an inductor-capacitor configuration with a low noise EMI filter module. The filter is designed to filter out wideband interference, as well as narrowband interference and power supplies spikes. It is also designed to reduce unwanted impulsive noises through its wide cut-off frequency, while still providing smooth transitions without any anomalies.

In addition, the SRF1280-330M also operates on a low voltage and has low power dissipation, thus allowing it to perform in a multitude of applications, including circuit protection, audio signal conversion, radio frequency, and more.
