MONOLITHIC CRYSTAL FILTERS  
ECS’s Monolithic Crystal Filters have very  
FEATURES  
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  
High stability for wide temperature ranges  
• Sharp cut-off  
• RoHS Compliant (Pb Free)  
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.
