Common Mode Chokes are a type of electrical device that limits the transmission of certain electrical signals. SRF2012-361YA is a common mode choke designed specifically for the application field of high frequency switched-mode power supplies (SMPS) and most applications of AC common mode filters.

This device is designed with a unique internal structure that increases its common mode suppression effect. Its inductance value is 2-(0.25)uH, making it ideal for applications that require a wide band noise suppression. Its parasitic capacitance is also lower than other comparable components, with a value of 8-(1)pF. It also has a DC resistance of 0.4-.05ohm.

As stated above, the SRF2012-361YA was designed primarily for the application field of high frequency switched-mode power supplies. In this application field, it is used to filter out unwanted noise generated by high-speed switching devices. It also suppresses radiated EMI and high frequency common-mode noise. In general, this device is used to eliminate the interference of the output circuit and prolong its life.

In addition to the application field of SMPS, this device can also be used as an AC common mode filter. This application field requires the device to operate at a relatively low impedance frequency band. This is where the SRF2012-361YA excels, as its inductance value is low enough to operate at this frequency range. This makes it an ideal device for this kind of application.

The working principle of the SRF2012-361YA is very simple. It works by utilizing an inductive loop that is designed to create a magnetic field. This magnetic field then works to restrict the flow of certain unwanted electrical signals such as noise, interference, and EMI. In this way, the unwanted signals are filtered out and the desired signals remain unaffected.

This device is also designed with a unique thermal design structure in order to help it perform under severe environmental conditions. This design structure includes a dielectric insulation layer, a ferrite core, and an isolation buffer.

Overall, the SRF2012-361YA is an excellent choice for a wide range of common mode filtering applications. Its unique design structure provides superior performance in applications like high frequency switched-mode power supplies and AC common mode filters. It is also designed with a thermal design structure that helps it perform in adverse environmental conditions.
