The SPH4012S-2R2MT with SMD,4.2x4.4x1mm inductor is a power inductor manufactured by Linekey that is RoHS compliant. This inductor has a low profile, making it suitable for applications with limited board space. It has a high saturation current of 10.5A, allowing for greater current handling capability. Additionally, it has an operating temperature range of -40C to +125C and its self-resonant frequency is up to 450MHz. Its direct current resistance (DCR) is only 0.07 Ohms, making it very efficient. It also has good temperature stability and high reliability. Lastly, its high current capacity makes this component ideal for use in power-related applications such as power management ICs, DC/DC converters, and more.
