AVX has developed the Active Filter Series to address the emissions and
susceptibility problems typical of today’s high speed digital circuits. The
Active Filter Series is the equivalent of back-to-back Zener diodes and an
EMC capacitor integrated into a single 0603 SMT case size. In its off
state the Active Filter Series can be used to attenuate EMI/RFI. Typical
values of attenuation at 3dB are 450MHz - 5000MHz, and typical values
of attenuation at 10dB are 950MHz - 2600MHz. A more definitive
representation of the filter effect is shown in the S
21
curve.
One of the specific advantages of the Active Filter Series is a consistent
EMI attenuation across a large bandwidth (without multiple frequency
poles occurring). This makes compliance to Electromagnetic
Susceptibility and Emission Specifications such as FCC Part 68, SAE
J1113 and IEC 61000-4-2 a much easier task for the designer.
