Fixed Inductors are specialized components, used when electrical engineers are confronted with problems involving the flow of current and magnetic fields. The SRP2512-1R5M is a special type of fixed inductor from the SRP2503/2506 series. In this article, we will look at the applications of the SRP2512-1R5M and the underlying working principle. The SRP2512-1R5M is a special type of inductor, designed with a through-hole mounting and low DC resistance. At just 7.6mm in size, it’s one of the smallest through-hole fixed inductors on the market. Due to its small size, it’s well-suited for applications where space is limited.It’s components are classified based on their inductance value, with a range of 1.5 - 1.75 uH and a high current assortment of up to 3.6A. It also features a maximum operating temperature of 100°C and an insulation resistance of up to 1.5G for guaranteed reliability and performance. The SRP2512-1R5M is also available in special features like low DCR, non-magnetic housings, and highly reliable metallurgy.Given all of these features, the SRP2512-1R5M is best-suited for power line noise filtering and power supply applications. The high operating temperature and its low DC resistance also make it suitable for converter and switching power supply. Its small size and high current also make it suitable for a variety of different DC/DC converter applications, including space-saving applications with close proximity components.The working principle of the SRP2512-1R5M is fairly straightforward. It is composed of two main parts, an iron core and a coil windings which carry currents. When current is applied to the windings, it creates and induces an opposing magnetic flux in the core which results in a back EMF – or electromotive force. This EMF opposes the applied current, and the amount of opposition is determined by the inductor’s inductance value. The higher the inductance value, the greater the opposition and vice versa. As the inductance value increases, the current decreases, allowing for better signal attenuation in power line noise filtering applications. In other applications, such as power supplies, the high inductance value provides for greater filtering capability. The SRP2512-1R5M is specially designed to have a low DC resistance, meaning it will have greater resistance to fluctuations in current conditions and will increase its reliability in power supply applications.The SRP2512-1R5M is a versatile and reliable fixed inductor, built with a through-hole mounting and low DC resistance feature. Its smaller size and high inductance value make it suitable for multiple applications, like power line noise filtering, converter and switching power supplies, and space-saving DC/DC converter applications. Its underlying working principle involves the induction of a back EMF, which opposes the applied current, providing better
