Selection Guidance
When selecting this ferrite bead, consider the DC resistance and rated current, which are to be verified based on specific application requirements. The impedance at 100MHz is a key parameter for noise attenuation; ensure it matches the frequency of the unwanted noise. For higher current paths, alternative TDK series with lower DCR may be more appropriate. Always refer to the official datasheet for detailed specifications and derating curves.
