To help designers easily incorporate Vishay’s surface-mount ferrite beads into any application for filtering, the calculator eliminates the need to determine impedance information from the Z vs. frequency graph in product datasheets. As applied DC lowers the effective impedance of the ferrite bead due to saturation, the new tool also removes the guesswork in determining how much impedance is reduced. This helps designers achieve the desired circuit impedance without having to experiment with several different values.
The new ferrite bead impedance calculator can be used with Vishay’s surface-mount ferrite beads in the 0603, 0805 and 1206 case sizes.
