P3519-224K

Fixed Inductors

Fixed inductors, also known as choke coils, coil radiators, or filter coils, are passive components that store energy in the form of a magnetic field. They are used in DC blocking, energy transfer, output filtering, and impedance matching circuits. There are different types of fixed inductors available, such as piston type, screen type, transformer type, drum type, and base type. These can be found in different applications such as instrumentation, communications, automotive, and military electronics.

P3519-224K application field and working principle

The P3519-224K is a type of fixed inductor with an impedance rating of 224⁠Ω +/- 10%. It is rated at 8.5 A (max) and has an inductance value of 220 µH (nH) nominally. It has a self-shielding construction with mesh shielding inside to minimize external noise interference.

The P3519-224K is mainly used in automotive, industrial, and consumer applications. It is designed as a low-profile, high current inductor and is suitable for switching mode power supplies and DC to DC converters. It can also be used as an output filter in audio amplifiers and audio equipment systems.

The working principle of the P3519-224K is based on Faraday\'s law of induction. When electric current passes through the coil, it creates a magnetic field, which in turn induces a voltage in the coil. This induced voltage opposes the applied current, and a certain amount of energy from the applied current is stored in the magnetic field.

The stored energy in the magnetic field allows the P3519-224K to act as an inductor, with the current ramping up and down at a controlled rate. This is critical for maintaining stability in the circuitry. The P3519-224K can also be used to filter out noise and to match impedance between components.
