Additional Details:

The RLF7030-4R7M3R4 has an inductance value of 4.7µH. The 'M' in the part number indicates an inductance tolerance of ±20%. The saturation current and rated current are important parameters to consider when selecting this inductor for a specific application. Consult the TDK datasheet for the precise saturation and rated current values under different operating conditions and temperatures. The inductor utilizes a ferrite core material optimized for power applications. The operating temperature range typically spans from -40°C to +125°C. The self-resonant frequency (SRF) is also an important parameter to consider for high-frequency applications, as it indicates the frequency at which the inductor's inductive behavior starts to diminish.
