Product Description

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.

  • High stability for wide temperature ranges
  • Sharp cut-off
  • Bandwidth:7.5kHz ~ 30kHz
  • Frequency - Center:10.7MHz ~ 21.4MHz
  • Impedance:850 Ohms ~ 5.5 kOhms
  • Insertion Loss:1.5dB ~ 2.5dB
  • Mounting Type:Through Hole
  • Number of Poles:2 ~ 4
  • Operating Temperature:-20°C ~ 70°C
  • Packaging:Bulk
  • Ripple:0.5dB ~ 1dB
