Fixed inductors are an important component in the circuit of electronic products. They are usually used in power supply, filter, resonator, delay circuit, etc. 2474R-48J is one kind of fixed inductors, and its application field and working principle are as follows.

2474R-48J is a common-mode inductor inductor, widely used in the production of power adapters, charger, ac/dc and dc/ac converters, switching power supply, etc. It can reduce cable core electromagnetic emission, improve signal integrity and remove common-mode interference.

The working principle of 2474R-48J is that the high frequency current of the DC power supply passes through the two coils in opposite directions, generating a changing magnetic field, which generates a return magnet field to suppress the radiation and cancel the common mode noise. As shown in the figure below, the electric current enters the coil through one port and returns to the source through the opposite port. Since the current direction of the two coils is opposite, the magnetic field formed by the two coils can be compensated, thereby reducing the radiation of the electromagnetic wave.

2474R-48J has many advantages. First of all, it has high power, good common mode interference and good EMC performance. Secondly, it is of low resistance and low thermal resistance. Thirdly, it is a kind of self-shielding component that has good shielding effect for high frequency current. In addition, it has good reliability and long service life. It can be widely used in the electric products with high frequency current.

In summary, 2474R-48J is one kind of fixed inductors used in power supply, filter, resonator, delay circuit, etc, and its working principle is the generation of high frequency current and the application of self-shielding components. This product has many advantages, such as stable and reliable performance, long service life, low thermal resistance and good EMC performance. Therefore, it is widely used in production of power adapters, charger, ac/dc and dc/ac converters, switching power supply, etc.
