ECS ECS-21K30D Monolithic crystal filter Datasheet

MONOLITHIC CRYSTAL FILTERS
ECS’s Monolithic Crystal Filters have very
high Q’s and excellent temperature and
aging characteristics. These filters offer
narrow and intermediate bandwidths. The
monolithic crystal filter is smaller and more
cost effective than a discrete crystal
filter. With the addition of coupling
capacitors between two-pole sections, they
can be cascaded to produce four, six and
eight (or more) pole filter responses.
FEATURES
• High stability for wide temperature ranges
• Sharp cut-off
• RoHS Compliant (Pb Free)
