Inductors are passive electronic components which characteristically store electrical energy and offer opposition against the rapid changes in the current or voltage. They are largely classified into two types viz. fixed inductors and variable inductors. Fixed Inductors take up definite amount of inductance and do not allow much variation. They are commonly used for electronic applications like radio systems, antennas and high frequency communications. The resistor symbols which represent a fixed inductor are depicted below. The B78148T1152K is a type of fixed inductor which has various specifications and uses.

Application Field

The B78148T1152K fixed inductor can be applied to high frequency communication systems. It is typically used as a balancing device for high frequency, low power radio receivers and transmitters. The high frequency signals can be handled efficiently with this fixed inductor since it has low insertion loss and good return loss. This aids the proper operation of the high frequency equipment without much lag. It is also used in audio applications since it has a high self resonant frequency and low equivalent series inductance.

Working Principle

Eddy current are induced in the conductor when current passes through the inductors. Hence, the higher the frequency of the current, the higher would be the eddy current generated. Eddy currents consume the energy from the current passing through the conductor thus producing opposition to the flow of current (Ohm’s Law). Fixed inductors allow only current with a definite frequency to pass through them and offer high resistance to the other frequencies.

The B78148T1152K is a high frequency fixed inductor which can be used to block high frequency signals and make operational those signals that possess desirable frequency only. Thus, it can be utilised to effectively pass the signals as in the case of high frequency / low power radios. In addition, it has very low equivalent series inductance.

It allows a low amount of AC ripple, high efficiency and small size and it is also appreciated as being highly reliable and easy to integrate in various designs.

Conclusion

The B78148T1152K fixed inductor is a high frequency electronic device which is used in a variety of radio systems, antennas and high frequency communication systems and helps in passing low ripple AC signals. It is ideally used to isolate signals that are of particular frequency and block the others. Thus, it is an important electronic component for high frequency operations.
