Fixed Inductors

The SLF6028T-101MR42-PF is a fixed inductor, also known as a choke, with an inductance of 10uH (10 microhenries). It is made of a ferrite core wrapped in a copper wire, and it has a saturation current of 4.5A. It is designed for use in switching power supplies, resonant circuits, and other applications that require high inductance and high current.

Application Field

The SLF6028T-101MR42-PF is typically used in switching power supplies, DC-DC converters, resonant circuits, electromagnetic interference (EMI) filter applications, and other high current, high inductance circuits. It is particularly well-suited to switch-mode power supplies and other switching applications that require high-frequency operation. In such applications, the inductor helps minimize high frequency noise, reduce power losses, and increase efficiency.

Working Principle

An inductor is essentially an electrical component which stores energy in the form of a magnetic field. When an alternating current is passed through the inductor, the changing magnetic field produces an induced voltage. This induced voltage opposes the current, and the amount of opposition is directly proportional to the amount of magnetic field or inductance.

In the case of the SLF6028T-101MR42-PF, the inductance is 10uH, which means it is capable of storing 10 microhenries of energy in the form of a magnetic field. This provides a high amount of impedance, or opposition, to changes in the current. This makes it ideal for high-frequency applications, as it can better suppress noise and prevent power losses.

In addition, the SLF6028T-101MR42-PF has a saturation current of 4.5A. This means that at currents of 4.5A or higher, the inductor is no longer capable of storing energy in the form of a magnetic field, and the voltage across the inductor will drop to zero. It is important to note that this drop in voltage occurs very quickly, and it is this characteristic which makes the inductor useful in switch-mode power supplies and other high-frequency applications, as it helps to limit the current when the switch suddenly opens or closes.

Conclusion

The SLF6028T-101MR42-PF is a fixed inductor with an inductance of 10uH and a saturation current of 4.5A. It is designed for use in high-frequency applications such as switching power supplies, resonant circuits, and EMI filters, due to its high inductance and saturation current. It helps reduce power losses, minimize noise, and increase efficiency.
