B material: This type is perfectly suited for fast digital signals.
By equalizing R components and X components that
beads possess at a frequency of 5MHz, it is able to
suppress overshooting, undershooting and ringing of
fast digital signals.

frequencies and sharply increasing impedance at high
frequencies. Designed for high impedance at high
frequencies (300MHz to 1GHz) for signal line
applications.
F material: This new product inherits the characteristic of our
D-material, namely its sharp impedance rise time, and
its impedance peak frequency has been shifted higher
into range.
