Fixed Inductors: SCIHP0718-8R2M Application Field and Working Principle

Fixed inductors, also known as chokes, are devices used in both DC and AC electrical circuits to pass through current while blocking certain frequencies. It is a passive two-terminal electronic component that stores energy in the form of a magnetic field. SCIHP0718-8R2M is a type of fixed inductor, and its application field and working principle should be discussed in detail in order to better understand it.

Application Field of SCIHP0718-8R2M

SCIHP0718-8R2M is an electronic part which is mainly used in televisions, radio sets, navigation systems, and other audio and video equipment. It can also be used as an oscillating and filtering circuit, a voice frequency circuit, and an automatic gain control circuit. In addition to that, this type of inductor can be used in power supplies, telephone and mobile circuits, as well as in communication circuits and testing instruments.

Working Principle of SCIHP0718-8R2M

Fixed inductors, such as the SCIHP0718-8R2M, work on the principle of electromagnetic induction. A coil of wire is wrapped around a core material—usually ferrite—which creates a magnetic field around the coil when current passes through the wire. This field will produce a voltage which opposes the current, resulting in a decrease in the current—thus providing a filtering or impedance effect. Additionally, since the current is in the form of alternating current, a counter-electromotive force is also generated which acts against the field. This opposing force causes the inductor to store energy in the form of a magnetic field, and then release it back into the circuit when the current changes direction.

In the case of the SCIHP0718-8R2M, this inductor operates in the temperature range between -40°C and +125°C. Its inductance range is between 0.8µH and 3.92µH, and its rated current is rated at 1.6A. It has a typical resistance of only 0.438Ω and a low profile at only 7.0mm.

Conclusion

In conclusion, the SCIHP0718-8R2M is a type of fixed inductor which is mainly used in various electronic and communication circuits. It operates on the principle of electromagnetic induction, and its temperature range is between -40°C and +125°C.
