Fixed Inductors: 2474R-22L Application Field and Working Principle Fixed inductors, also known as chokes, are electronic components consisting of a number of winding coils wound around a magnetic core. This allows the inductor to store electrical energy when current passes through it. Inductors are mainly used to improve signal quality and act as filters. The 2474R-22L is a fixed inductor manufactured by Yageo Corporation. It is designed for a wide range of applications and is ideal for impedance matching and noise suppression. The 2474R-22L is a small, low profile, through hole inductor with a maximum operating temperature of 140°C. Inductors are mainly used in alternating current (AC) circuits, where they are used to either induce a voltage (as in transformers) or provide impedance matching (also known as impedance bridging). The 2474R-22L is designed to provide impedance bridging and is particularly suited to low frequency signals. This allows it to act as a filter, allowing AC signals to pass while blocking DC electrical signals. This makes the 2474R-22L ideal for use in audio and video equipment, such as TVs and amplifiers, where it reduces noise and interference.The working principle of the 2474R-22L is based on the concept of inductance or inductive reactance. When electrical current passes through the 2474R-22L, it creates an electromagnetic field around the device. This field induces a voltage, which opposes the current and causes the inductor to resist the flow of current. The magnitude of the induced voltage is proportional to the rate of change of current, which is why the 2474R-22L is ideal for filtering low frequency signals. The 2474R-22L is also capable of acting as a ‘choke’, meaning that it isolates and regulates the supply of power to the circuit by limiting the amount of current passing through the device. This is achieved by the inductor’s ability to store electrical energy and release it at a slower rate. This is particularly useful for reducing spikes in current, limiting over-voltage and in-rush current.In conclusion, the 2474R-22L is a small, low profile, through-hole inductor specifically designed for use in audio and video applications. It has a wide operating temperature range, and is capable of providing impedance bridging and noise suppression. It works on the principles of inductance, and is able to act as both a filter and a choke, making it ideal for use in a variety of applications.
