Surface Mount
Lowpass Filter Series
Description
DLI introduces its new high frequency surface
mountable catalog lowpass filters. These
LPF’s incorporate DLI’s high dielectric ceramic
materials which provide small size and minimal
performance variation over temperature.
The catalog LPF’s are offered in a variety of
frequency bands, which offers a drop in solution
for high frequency attenuation.

Mounting Information
PCB ground pattern length and width can be 0.002-0.003 inches larger than filter footprint.
Dimensions of filter launch and PCB launch pattern should be closely matched. It is suggested
that PCB ground metal be pulled back from RF I/O trace to account for component alignment
tolerance. Ground via depth and spacing should be set so as not to create any resonances at
the frequency of operation.
Reference SMT Filter Mounting application note for additional mounting information.
Individual footprint diagrams of all Filters are available upon request from the DLI Sales Office.
