FEATURES
• The ACB series provide effective EMC suppression in signal lines
through simple in-series implementation. It is thus ideal for circuits in which it is difficult to bypass high-frequency components
to ground.
• Reflection components are highly suppressed through the use of
a special ferrite material and an advanced internal structure that
minimizes stray capacitance. This product is, therefore, an excel-
lent countermeasure for noise radiation in high-speed digital signal lines.
• The ultra-miniature 1.6 × 0.8 mm part exhibits a 600Ω impedance at 100MHz, which is the larger type 2012 and 3216 parts.
• Both the 1608 and 2012 types are available in a large number of
impedance values. Different characteristics can thus be
achieved without changing PC board land patterns.
