Fixed Inductors provide fixed values of inductance in circuits. P3519R-821J is one of the most common fixed inductors that are widely used in a range of circuits and applications.

This type of inductor is a medium power choke rated for 400V and 200mA. It consists of a coil wrapped around a ferrite core, and features a square shape. It has two through-hole terminals for connection to the circuit, and two solder centering pins, for mounting the device to a printed circuit board.

The P3519R-821J fixed inductor offers a wide range of application fields. It can be used to filter the signals in a power supply network to reduce voltage ripple. It is also used as a fixed frequency selectivity, allowing the selection and separation of frequencies, and as an acceptor or rejector of frequencies. Additionally, it can be used to temporarily store energy or as a circuit damping element to reduce resonance.

The working principle of this inductor is based on Faraday\'s law of induction. When a voltage is applied to the coil, a magnetic field is generated, resulting in an increase in the voltage across the inductor. The amount of inductance of this type of inductor depends on the number of turns in the coil construction, and the geometry and composition of the core and its surroundings.

The P3519R-821J fixed inductor is also designed to withstand high temperatures and humidity. It is made of corrosion-resistant material and features a thermally conductive adhesive layer between the core and coil for efficient dissipation of heat. It is also resistant to shock and vibration, making it suitable for use in harsh environments.

The P3519R-821J fixed inductor is used in a variety of industrial, consumer and automotive applications, from filtering signals in power supply networks to regenerating AC signals in test circuits. It is an ideal choice for a number of applications where reliable performance and consistent operation are required.
