Fixed Inductors are electrical components made of wire wound around a copper core and encased in an insulating material. The CK21256R8M-T is a fixed inductor from Murata, a manufacturer of electronic components. It is categorized as an Axial Leadhold Type inductor.

Applications for the CK21256R8M-T

The CK21256R8M-T is primarily used in power management applications, such as DC to DC converters, power supplies, and voltage regulators. The product is also used for high frequency filters and signal conditioning in audio and video equipment, clocks, and instruments.

The CK21256R8M-T has low DC resistance that allows for high current operation, as well as a high inductance to current ratio that enables it to be used in a variety of applications. This fixed inductor is suited for power applications with higher frequencies, which require precise performance control.

Working Principle of the CK21256R8M-T

A fixed inductor stores energy in a magnetic field as current flows through it. This energy is released as a voltage when the flow of current is stopped. The size and shape of the magnetic field are determined by the physical shape of the inductor, as well as by the amount of current passing through it.

The CK21256R8M-T is designed to handle higher frequencies, which require precise control of the inductance-to-current ratio. It also has low DC resistance, allowing for high current operation. The inductor’s shape and size also account for its ability to provide high frequency filtering, waveform distortion, and noise suppression. Additionally, its encapsulating material ensures durability and protection from external damage.

Conclusion

The CK21256R8M-T fixed inductor from Murata is a versatile component designed for use in power management applications. It has low DC resistance and a high inductance to current ratio, and it can be used in high frequency filters, signal conditioning, and other applications. This fixed inductor provides accurate performance control, high frequency filtering, waveform distortion, and noise suppression.
