Ferrite Cores are known for their high magnetic strength and superior resistance to thermal and mechanical breakdown. The 28B1250-2 is one type of ferrite core that has wide applications in the electrical and electronic industries. This article will discuss the application field of 28B1250-2 and its working principle.

Application Field of 28B1250-2

The 28B1250-2 is primarily used for transformers and chokes. In transformers, the 28B1250-2 is mostly used for medium and high frequency power transformers and pulse transformers. The core maintains consistent performance under both low and high power levels. The core is also used in chokes for high frequency RF applications, such as switching power supplies, radio transmitters, automobile audio systems, and other electronic equipment. The 28B1250-2 is also found in filters for AC power line.

Working Principle of 28B1250-2

The 28B1250-2 is constructed from a ferrite, ceramic material which has high dielectric loss properties, high permeability and low hysteresis loss, making it an ideal choice for EMI/RFI suppression. The core’s permeability range is between 400 to 600. The 28B 1250-2 also has excellent reluctance and thermal properties. The core is comprised of an outer sleeve, two clamping yokes, and two wedges which are separated by two gaps. The main part of the core is the ferrite itself, which is basically a block of ferrite that is ceramic coated.

The working principle of the core is based on the transformation of electrical energy to magnetic field energy, and vice versa. In transformers, the core serves as the medium for the conversion of electrical energy into magnetic energy, while the winding serves to transfer the energy between the primary and secondary circuits. In chokes and filters, the core is used to store magnetic energy from the alternating current, so that the current in the circuit remains steady.

Conclusion

The 28B1250-2 is a type of ferrite core with wide applications in the electrical and electronic industries. The core is primarily used in transformers and chokes for medium and high frequency power transformers and pulse transformers, and other RF applications. The 28B1250-2 is constructed from a ferrite, ceramic material and has excellent permeability, reluctance and thermal properties. The working principle of the core is based on the transformation of electrical energy to magnetic field energy.
