Abstract

The invention relates to piezoelectric resonators, and more particularly to piezoelectric resonators comprising a DT- or CT-cut quartz plate vibrating torsionally about its longitudinal axis which is the electrical axis X of the quartz crystal. The width of the plate b, extending along the Z'-axis, and its thickness h extending along the Y'-axis are linked by the relation 1<B/H<10 In proportion to its size, the resonator has a low resonance frequency, the temperature coefficient of the first order of which is nil and the temperature coefficient of the second order of which is very low.
