Cylindrical Crystal

BC49 - 9.3 x 3.1mm

Cylindrical crystals are crystal resonators used in applications with little or limited space on the PC board.  Used primarily for clock timing in communications equipment, measuring instrumentation, microcomputer control and other time management applications. Frequencies from 4.000 to 50.000 MHz are available.  Optimum for OA and AV applications.



Features
  • Ultra-miniature size
  • Fundamental or 3rd overtone strip AT-cut crystal
  • Wide frequency range
  • Low cost
  • Industry standard
  • Reflow soldering
