Fixed inductors, also known as chokes, are electrical components designed to provide a known inductance to a circuit. The P3519-184K is designed to have an inductive value of 184K, which is very useful for many applications, such as power supply regulation and filter design. The P3519-184K is a surface mount device, meaning it can be easily mounted onto printed circuit boards (PCBs).

Working principle

At the most basic level, a fixed inductor works by producing a magnetic field within its windings when a current is applied. This produces an opposing back-emf which opposes the applied current, resulting in a decrease in the current through the inductor. This is called Faraday’s Law, and it is essential for understanding the operation of any electrical component.

When designing a power supply regulator, the responsibility of the fixed inductor is to keep the voltage at a steady output. This is done by storing energy in the form of a magnetic field within the inductor’s windings. When the applied voltage increases to a certain level, the magnetic field stored in the inductor’s winding begins to oppose changes in voltage, reducing the increase in output voltage.

The P3519-184K fixed inductor also has the added benefit of providing EMI shielding in EMI sensitive circuits. EMI shielding is provided through the application of a metallic can around the inductor, which reduces the radiation of unwanted electromagnetic interference.

Application field

The P3519-184K, with its 184K inductive value, can be used for a variety of applications. Its most common use is in power supply regulation, where it can be used to maintain a steady and consistent voltage output. This is done by the inductor storing energy in the form of a magnetic field when a current is applied, and then releasing it back into the circuit to decrease the output voltage.

The P3519-184K can also be used in filter design. This is because the inductive value of the component helps to block high-frequency noise and unwanted electromagnetic interference (EMI) from entering or exiting the circuit. By blocking this noise, the filter can be designed to act as a bridge between two pieces of equipment.

The P3519-184K can also be used in signal processing applications. This is because it can be used to create high-impedance paths for signals travelling through it. In this way, the inductor can help to ensure that signals are not distorted by interfering signals in the environment.

Finally, the P3519-184K can be used for balancing circuits. This is because it can help to equalize opposing currents, allowing an even flow of electrons through the circuit. By creating a balanced circuit, power loss and other disturbances can be minimized.

Conclusion

The P3519-184K is a surface mount fixed inductor which is designed to provide an inductive value of 184K. The application field of this inductor varies, from power supply regulation, to filter design, signal processing, and balancing circuits. Besides these, it also provides EMI shielding in EMI sensitive circuits. The P3519-184K is a useful and versatile component, which should be considered for any electrical design which requires an inductor.
