Fixed Inductors

Inductors, also known as coils, chokes, or reactances, are devices composed of conducting wire wound into a coil. Their core function is to store energy in the form of a magnetic field and release it when the current flowing through it changes. To achieve this, inductors must have some resistance to changes in electrical current. This resistance is referred to as the inductance of the device.A fixed inductor is any device whose inductance is fixed and can’t be adjusted. The most common type of fixed inductor is the SRP1238A-1R5M. It is a surface-mount, multilayer inductor, featuring an operating temperature range of -40℃ to +105℃.The SRP1238A-1R5M has a wide range of applications. It can be used in a variety of circuits, including power supplies, audio amplifiers, converters, and DC/DC stepdown converters. Its high efficiency makes it ideal for high-voltage applications where power dissipation is an important factor.The SRP1238A-1R5M’s working principle is simple. When a current passes through the inductor, a magnetic field is created around it. This magnetic field stores energy, and the strength of this magnetic field increases with the amount of current. When the current drops, the stored energy is released in the form of an electric current. This working principle is the basis of all fixed inductors.The SRP1238A-1R5M is also characterized by its high durability, with an insulation resistance rating of 500Vdc and a DC resistance rating of 1.5 ohms. It also features a very low internal electrical noise, making it an ideal choice for applications that require quiet operation.The SRP1238A-1R5M is a highly efficient, durable, and cost-effective fixed inductor. Its range of applications and working principle make it an essential part of a wide range of electronic circuits. Its performance and reliability make it one of the most popular inductors on the market.
