Fixed Inductors- SRR1260-6R8Y application field and working principle

A fixed inductor, also known as a fixed inductor or fixed-value inductor, is an inductor that has a non-adjustable inductance value. Its main function is to store energy in the form of a magnetic field. SRR1260-6R8Y is a typical fixed inductor manufactured by Dongguan Huadong. This article briefly summarizes the application field and working principle of this product.

Application Field

SRR1260-6R8Y is a high-frequency fixed inductor, mainly used for signal filtering, matching, and other applications in the telecommunications modern. For example, it can be used in circuits such as signal transceivers and amplifiers for two-way radios, terminating transmitters, shortwave receivers, and FM radios. It can also be used as a load for harmonic wave generator and high frequency inverter. In addition, SRR1260-6R8Y can also be used for high speed digital circuits, frequency synthesizers, and global positioning systems.

Working Principle

SRR1260-6R8Y is an inductor with a fixed inductance value, which is mainly realized by using a coil of copper wire. When it is subjected to an AC voltage, an alternating current will be induced in the winding. The alternating current will also generate a magnetic field around the inductor, which will be used to store energy.Due to the self-inductance effect, the provided electrical power and energy in the SRR1260-6R8Y takes the form of a magnetic field that is generated by the induced current. This, in turn, generates a magnetic field proportional to the current magnitude and frequency, thereby providing an increase in inductive reactance. This reactance impedes the flow of current to varying degrees depending on the frequency of the alternating current applied. The self-induced current essentially creates a short-circuit to the main current, which raises the internal losses. Moreover, the stored energy within the SRR1260-6R8Y also contributes to the impedance. Its magnitude is determined by the product of the effective inductance and the rate of change of current. Since SRR1260-6R8Y is a fixed inductor, its parameters remain unchanged over time, thereby allowing it to act as an effective signal filter.

Conclusion

In summary, SRR1260-6R8Y is a high-frequency fixed inductor manufactured by Dongguan Huadong. It is mainly used for signal filtering, matching and other applications in the telecommunications modern. Its working principle is mainly based on the self –inductance effect. Due to its fixed inductance value, it is a very effective signal filter and can be used in many different applications.
