P3519-822K Application Field and Working Principle

The P3519-822K is a type of fixed inductor manufactured by Murata Manufacturing. As a fixed inductor, it is designed to operate at a certain frequency across a wide range of operating temperatures. It can be used in various applications including circuits, microwave ovens, computers, and more.

The P3519-822K consists of a core material, typically made of a ferrite material with a low resistance. It has a fixed inductance value, typically measured in μH. The surface mount configuration allows the P3519-822K to be easily mounted onto a printed circuit board. The inductor is typically rated in both peak pulse current and direct current, so it is important to ensure that the current specifications of the circuit are compatible with the inductor.

The P3519-822K\'s working principle is based on the inverse relationship between inductance and frequency. When a current is applied through the core material, the inductance increases as the frequency falls and drops as the frequency increases. This can be expressed mathematically as: L = 1/2πf. The opposite is true when current is changed at a fixed frequency—the inductance falls as the current is increased, and rises as the current is decreased. As a result, the P3519-822K can be used to control current in a circuit, as well as the frequency of the circuit.

The P3519-822K is ideal for use in a wide variety of applications. It can be used in filters, current sensing circuits, and voltage regulators. It is also well suited for high frequency applications, such as radio receivers, digital systems, and microwave ovens. The P3519-822K is a great option for manufacturers looking for a reliable and cost-effective inductor to use in their designs.
