Fixed Inductors

Inductors are electrical components that work similarly to capacitors in that they store and quickly release energy. Unlike capacitors, inductors draw energy in the form of magnetic fields, and quickly release the energy as electric current throughout the circuit. There are various kinds of inductors and one of them is the B82442T1125K050, which is a fixed inductor.A Fixed Inductor is an inductor that has been fixed or permanently mounted on the PCB. The most common use of a fixed inductor is to filter and reduce noise, such as radio frequency interference and electromagnetic interference, in a system. Thus, it is often used to provide power supply filtering and to reduce transient disturbance from wires connected to the power source. It can also be used to store energy, as well as to protect against voltage spikes.The specific B82442T1125K050 is a surface mount, leaded, unshielded power inductor, fabricated using a hull cell (bobbin) and a single ferrite core. It is rated at 250mA and operates at 125kHz. It features low DCR (0.056 ohms) and high current/power handling capabilities (up to 250mA, 1.125W). It is an excellent choice for high-performance, high-frequency application.B82442T1125K050 has multiple application fields. It can be used for DC-DC converters, switching power supplies, electronic ballasts, battery charging systems, power amplifiers, switch-mode power supplies and audio amplifiers, among many others. In these applications, B82442T1125K050 is used to create the inductance necessary to achieve the desired power efficiency, frequency response, current flow, signal replication, or to reduce unwanted harmonic components, power loss, or reduce noise.When working, B82442T1125K050 will store the current flow in its core winding due to induction. When the current increases, the stored energy (magnetic field) also increases, resulting in a higher inductance. When the current decreases, the stored energy decreases, leading to a decrease in the inductance. This effect is known as "self-inductance" and is the principle behind the operation of B82442T1125K050.B82442T1125K050 has a wide range of advantages such as cost effectiveness, compatibility, electrical efficiency, miniaturization and high power handling. It is also a highly reliable component, making it vastly preferred in many applications.In conclusion, B82442T1125K050 is a fixed inductor with multiple application fields, such as DC-DC converters, switching power supplies, electronic ballasts, battery charging systems, and more. It is an excellent choice for high-performance, high-frequency applications due to its low DCR, high current/power handling capabilities, and its capability to reduce unwanted harmonic components, power loss, and noise. The B82442T1125K050 is a highly reliable component and Thus, it is increasingly the preferred choice of inductor in many different applications.
