SRF1280-2R2Y is an important type of signal transformer, which is mainly applied in various arrays. Its application fields include communications, high-frequency transmissions, military, medical, and so on. It has high frequency characteristics and wide bandwidth. By understanding its working principle, one can have a better understanding and application of this device.

The core of the SRF1280-2R2Y device is a high-sensitivity component consisting of a copper wire, a ferrite core, and two windings. The wire and the core form a mutual electromagnetic induction loop. When the coil is connected to an oscillating voltage source, such as a radio frequency (RF) signal, the induced current in the coil produces a magnetic field in the ferrite core. The magnetic field will induce a current in the second winding, which is connected to an electronic device, such as a radio receiver.

When the external RF signal is incident to the transformer, the induced current of the first winding produces a magnetic field in the ferrite core. This magnetic field will induce a voltage in the second winding. The transformer works by providing an isolated, higher-level voltage for the second winding. Thus, a power gain is achieved, and the signal will become a much larger voltage, which is more usable for the attached electronics.

SRF1280-2R2Y not only works as a voltage amplifier, but also as an impedance adjustment device, which can evenly divide the power between the two wiring pairs. The devices can be found in various applications due to their low speed factor, high dielectric strength, low insertion loss, and their strong anti-interference ability. For example, they are used for matching in RF amplifiers, impedance matching in antenna array systems, harmonic filters, and so on.

In summary, SRF1280-2R2Y is an important type of signal transformer belonging to the array category. It is most often seen in communications, high-frequency transmissions, military, medical, RF amplifiers, antenna array systems, and harmonic filters. It has a high-sensitivity component consisting of copper wire, a ferrite core, and two windings, which produces a magnetic field in the ferrite core, subsequently inducing a current in the second winding. The device can amplify voltage, even power between two wiring pairs, and has low insertion loss, making it suitable for various applications.
