Cylinder Crystal

BC54 - 6.3 x 2.0mm

BC54 is a cylinder crystal measuring 6.3mm long and 2.0mm in diameter. Cylinder 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 6.000 to 30.000 MHz are available.  Optimum for OA and AV applications.
