MMZ1608 type
MATERIAL CHARACTERISTIC
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.
R material: For wide frequency applications calling for broad impedance characteristics. For digital signal line applications calling
requiring good waveform integrity. Impedance values selected for effectiveness at 10 to 200MHz.
S material: Standard type that features impedance characteristics similar to those of a typical ferrite core. For signal line applications in
which the blocking region is near 100MHz. Impedance values selected for effectiveness at 40 to 300MHz.
Y material: High frequency range type intended for the 100MHz region and above. For signal line applications in which the signal
frequency is far from the cutoff frequency. Impedance values selected for effectiveness at 80 to 400MHz.
A material: This high-impedance product is based on the impedance frequency characteristics of our Y-material. The product offers
excellent impedance characteristics, which is greater than 2500, in the vicinity of 100MHz range (MMZ1608A252B).
Q material: High frequency range type intended for the 100MHz region and above. Impedance values selected for effectiveness at 100 to
800MHz.
D material: For applications calling for low insertion loss at low 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. The product offers excellent noise suppression from 600MHz to as high as in
the GHz range.
