Fixed inductors (or sometimes called chokes) are components which are used to store energy in an electric or magnetic field. They are usually composed of an inductive coil, either of ferrite or air gap core, with additional electronic components surrounding it. These inductors can be used in a variety of applications, most notably in power supplies, where they can be used to smooth the output voltage. Additionally, they are used as filters for specific frequencies in communications and EMI shielding.The 2109-H type fixed inductor is one type among many, and it has become increasingly popular in recent years. The 2109-H inductor is designed to be very small and efficient yet highly capable when it comes to providing EMI/RFI shielding, power filtering, and current limiting. It is constructed with a high permeability ceramic core and copper winding, and is highly resistant to corrosion and environmental variations.The 2109-H also has a wide range of applications, from automotive power supply to commercial vacuum cleaners. It can also be used in various hobby projects, from radios and amplifiers to clocks and other audio devices.When it comes to the working principle of the 2109-H inductor, it is the same as any other inductor. When a coil of wire is placed within a magnetic field, the electrons in the wire move in circles, and this creates an alternating current. This current is the basis for the inductive response of the coil, and it is what allows the inductor to store energy in an electric field.When voltage is applied across the inductor, a current begins to flow, which produces a magnetic field which is proportional to the current. This magnetic field in turn induces a second voltage across the inductor, which is the basis for the inductive response. This response is then used to filter the input current, providing a smooth and steady output.In addition to this, the inductor can also serve as an EMI/RFI shield, preventing electromagnetic signals from entering or leaving the circuit. This is done by allowing the magnetic field induced by the current to pass through the shield, which in turn absorbs the electromagnetic waves produced by the current. The result is a smoother output signal which is free from interference.Overall, the 2109-H type inductor has earned itself a reputation for being one of the most popular, versatile, and reliable types of inductors available on the market. It is a great choice for a wide range of applications in the automotive, hobby, and industrial sectors, as it offers excellent performance in shielded environments. Whether it’s for EMI/RFI shielding, power filtering, or current limiting, the 2109-H is an excellent choice.:
