Fixed inductors are fundamental components of electronic circuits which typically consist of two or more conductive portions, such as wires or coils, that are generally made from ferromagnetic material such as iron or steel. These inductors have a fixed inductance value that does not change with increasing or decreasing current or power levels. Fixed inductors are used for a variety of applications in a range of electronic devices, including computers, mobile phones, home appliances, and many types of automotive devices. The CW252016-R39G is a type of fixed inductor manufactured by CoilCraft, a leading provider in the industry.

The CW252016-R39G is a through-hole inductor with a total case size of 25mm x 16mm. It has an inductance value of 33.2 ±20% μH, a saturation current of 24A and a direct current resistance (DCR) of 0.082 Ohm. It is made from ferrite toroidal cores and 0.51mm (20 AWG) tin plated copper wire and is terminated with standard copper-plated solders. The CW252016-R39G is RoHS compliant and is rated at 125°C.

The CW252016-R39G can be used for various applications, including switching power supplies, converters, inverters, TV tuners, amplifier circuits, zero crossing detection circuits, and similar power-demanding electronic devices. Its high inductance value and ability to handle current spikes make it well suited for these types of applications. Additionally, the low DCR of the CW252016-R39G reduces power loss and reduces circuit size. Furthermore, its low resistance also increases its efficiency and improves cost savings, making it an ideal choice for industrial power electronics.

The working principle of a fixed inductor is based on Faraday\'s law of induction. When a changing magnetic field is present, it creates an electromotive force (EMF) in the coil, producing a current in the opposite direction. This is known as self-induction. The presence of the coil in the magnetic field also produces a self-inductance, creating an EMF which opposes changes in the current flow. This EMF helps to prevent current spikes. Furthermore, the core material of the CW252016-R39G helps to increase the inductance value and also to reduce current leakage.

In conclusion, the CW252016-R39G is a type of fixed inductor which is well-suited for demanding power applications. Its high inductance value, ability to handle current spikes, and low DCR make it an ideal choice for industrial power electronics. The working principle of a fixed inductor is based on Faraday\'s law of induction. This law states that a changing magnetic field produces an EMF which opposes changes in the current flow. This EMF helps to prevent current spikes and also helps to increase the inductance value. The core material of the CW252016-R39G helps to reduce current leakage and further enhances the performance of this inductor.
