For Proper Use of Crystal Units
1. Characteristics of crystal units
(1) Relationship between thickness of crystal blank and oscillation frequency
(2) Examples of specifications for frequency-temperature characteristics
(3) Equivalent electric circuit and equivalent constant of crystal unit
The thickness of crystal vibrator of the AT cut crystal unit as described in the previous page differs depending on the
overtone mode.
The frequency-temperature characteristics of the AT cut crystal unit are tertiary curves.
The diagram below shows examples of the tertiary curves that pass temperature range and frequency deviation specifications.
The range enclosed by the smaller rectangular satisfies the following specification:
The range enclosed by the larger rectangular satisfies the following specification:
The following equivalent constants are used near the resonance frequency.
