P3519R-124J Inductors, Coils, Chokes

Inductors are passive electrical components that store energy in the form of magnetic fields when a current flows through them. In general, inductors are coils of wire wound around a core, the core usually being air or a ferromagnetic material. They can come in several types such as iron core inductors, air core inductors, and specialty inductors. The P3519R-124J is an example of a specialty inductor and is categorized in the fixed inductor section.

The P3519R-124J is a 1.2 mH radial leaded inductor with a tolerance of +/-20%. They are ideal for a wide range of applications including power supplies, DC/DC converters, and low-noise transformers. Its high efficiency and low DC resistance makes it suitable for filtering and matching applications such as EMI/RFI filter networks and impedance matching circuits. It also offers superior frequency and temperature stability with its shielded construction.

The working principle behind the P3519R-124J is simple: when an alternating current flows through the coil, it creates a magnetic field around it due to Inductance. The magnetic field induces a voltage in the coil, and this voltage opposes the alternating current that originally created it. This opposition or impedance opposes the flow of current and it is this effect that the P3519R-124J takes advantage of in various applications. Furthermore, because a magnetic field persists after the current has ceased, inductors store energy.

Compared to other inductors, the P3519R-124J offers many advantages. It has a wide range of operating temperatures from -40°C to +125°C, low DC resistance of 1.6mΩ, and very low inductance change of 0.2%. It is RoHS compliant and halogen free, ideal for applications in harsh environments. Moreover, it utilizes a shielded construction that delivers superior performance in frequency and temperature stability. Finally, it comes in an axial package, making it easy to install and work with.

Overall, the P3519R-124J is an excellent option for a variety of applications. Its low DC resistance, wide range of operating temperatures, and its shielded construction make it ideal for filtering and match applications. Its axial package provides great flexibility and makes it easy to work with. This fixed inductor is well suited for applications ranging from power supplies and DC/DC converters to EMI/RFI filter networks and low-noise transformers.
