Low Pass LC Filter Modules
Coilcraft’s family of low pass LC filters are available in 3rd
order Butterworth and 7th order elliptical alignments. These
space saving SIP filters offer all the benefits of an LC
design: low insertion loss, high power handling and con-
trolled group delay.
Built using Coilcraft’s tight tolerance surface mount induc-
tors, these filters can be readily customized to meet your
specific requirements.
• 3rd and 7th order alignments
• 50 Ohm characteristic impedance (75 Ohm versions
also available)
• Less than 0.3 dB insertion loss
Coilcraft
Designer’s Kit D301
contains samples of the
filters shown in bold. To order, contact Coilcraft or visit
