Fixed inductors are electrical components consisting of two terminals, normally terminated with leads, designed to withstand a certain voltage and current at a desired frequency for a given application. The PCMB135T-R68MS is a fixed inductor from Murata Electronics in the Power Choke series that is suitable for use in low profile applications such as small consumer electronics. It is specifically designed to reduce power losses due to core losses, increase frequency switching range, and reduce the volume of AC ripple noise.

Application Fields:

The PCMB135T-R68MS inductor is suitable for use in a range of applications, including line filters, power supplies, and DC/DC converters. Because of its low profile, it is ideal for use in portable or handheld consumer electronic devices, such as smartphones and tablets. It is also suitable for applications requiring low power losses due to its high inductance and DC/DC conversion capacity.

Working Principle:

The PCMB135T-R68MS uses core losses to reduce power losses, increase frequency switching range, and reduce the volume of AC ripple noise. In the core of the device, the ferrite core material is surrounded by an axial copper wire, which acts as an electrical conductor. The current passes through this conductor, creating a magnetic field in the core material. This magnetic field produces a back EMF, which opposes the electric field from the current, resulting in a loss of power due to the resistance of the core material. This loss of power reduces the ripple current and frequency range, and thus reduces the power losses associated with the inductor.

Conclusion:

The PCMB135T-R68MS inductor from Murata Electronics is an ideal choice for use in low profile applications, including those that require low power losses due to core losses. It has the capacity to reduce the volume of AC ripple noise, as well as increase frequency switching range. As such, it is a versatile component, suited for use in a variety of consumer electronics, power supplies, and DC/DC converters.
