Fixed Inductors

A fixed inductor is an electronic component that is capable of producing a constant amount of inductance in an electronic circuit. Since inductors are used in many types of electronic circuits, the specific type of inductor that is chosen for a particular application will depend on its characteristics and the needs of the circuit. The 2534R-28H application field and working principle is one such example.

Application Field

The 2534R-28H is a miniature coil form inductor commonly used for switching power supplies, switching regulators, and amplifiers. This inductor has a very high self-resonant frequency of 75 MHz and is suitable for high speed frequencies. It contains a ceramic core which provides high Q factors and efficient operation and is wound with a spiral copper-clad aluminum wire for maximum efficiency. The inductor is also suitable for medium power applications such as PC power supplies and power transformers.

Working Principle

The 2534R-28H works on the same principle as all other inductors. When an electrical current is passed through a conductor, a magnetic field is created. This magnetic field then induces an electrical current in another part of the circuit. The amount of current induced is proportional to the amount of current applied to the inductor, and this current is called the back electromotive force (back emf). The back emf will reduce the amount of current that can be supplied by the inductor.

The amount of inductance of an inductor is determined by the cross-sectional area of the conductor and the number of turns of conductor on the inductor. The 2534R-28H has a rated inductance of 3.9 μH, which means that it can hold 3.9 micro-henries of current with one turn of conductor. To increase the inductance of an inductor, you must either increase the number of turns of the conductor or increase the cross-sectional area of the conductor. The 2534R-28H is unshielded and has a maximum rated temperature of 135°C, allowing it to be used in high-heat applications.

Conclusion

The 2534R-28H application field and working principle are important to understand when choosing inductors for electronic circuits. Not all inductors are suitable for all applications, and it’s important to consider the characteristics of each type of inductor when deciding which to use. The 2534R-28H is suitable for high speed frequencies, medium power applications, and high-heat applications. It has a high self-resonant frequency and is wound with an efficient copper-clad aluminum wire.
