TUNING FORK Q UARTZ CRYSTAL

TC-26 & NC-38 Series

FEATURES

The tuning fork type quartz crystal provides

ultimate in size, performance, and economic

trade-offs. So it is used as a clock source in

communication equipment, measuring instr-

ument, microprocessor and other time man-

agement application.

F/f(ppm)

T o determine frequency stability , use parabolic curvature(k).

For example: What is stability at 45

1).change in T( )=45-25=20

2).Change in frequency = -0.042ppm*(

= -0.042ppm*(20)²

)

= -16.8ppm(max)
