ECS-21K-15A

Monolithic Crystal Filter 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.
