FP1005R3-R22-R Inductors, Coils, Chokes

FP1005R3-R22-R fixed inductors are widely used in various electronic circuits. They are also called surface mount inductors. They are miniature inductors, which are directly soldered onto a printed circuit board (PCB). With their small size and good performance, fixed inductors have been widely used in many electronic products.

The working principle of a fixed inductor is actually very simple. It consists of one or more turns of wire wrapped around a core, like a small coil. When electric current passes through the coil, it produces an inductor current (i) in the coil. The current i generates a magnetic field in the inductor, which is proportional to the amount of current in the coil.

Depending on the type of application, the fixed inductor can be used to create a resistor, a capacitor, or a transformer. It is common to use a fixed inductor in power supplies, converters, and switching regulators. In these applications, the inductor acts as an energy storage component, collecting the energy created by the electric current in the coil and storing it for later use.

In addition, fixed inductors are used in various communication systems, such as modem, ADSL, CATV, and cable TV systems. In these systems, the inductor is used to connect the incoming telephone line to the digital processor, allowing the processor to read and decode the signal. It also serves to reduce electrical interference between different signals, making communication between the system and the user more reliable.

Fixed inductors are also used for noise suppression in electronic circuits. By placing one or more induced coils in parallel with the circuit, the noise in the circuit is greatly reduced. This is because the coil of the inductor will generate a magnetic field that acts as a shield for the electric current. By creating this shield, the noise generated by the electric current is effectively suppressed.

In addition to their use in communication systems and noise reduction, fixed inductors are also widely used in DC-DC converters and switching regulators. In these applications, the inductor acts by controlling the flow of current in the circuit. By increasing or decreasing the current, the inductor can effectively regulate the power in the circuit, ensuring that the power supply is stable and reliable.

As a low-cost and widely available electronic component, fixed inductors are used in a wide range of applications, from communication systems to power supplies. They are highly reliable and easy to use, making them a great choice for a variety of electronics applications. With their many benefits, fixed inductors continue to be a popular choice for many designers and engineers.
