AT Cut Quartz Blanks Low Temperature Etching 0.5MHz - 70MHz

AT Cut Quartz Blanks Operating In Wide Temperature Range

AT cut is the most common cut, developed in 1934. The plate contains the crystal's x axis and is inclined by 35°15' from the z (optic) axis. The frequency-temperature curve is a sine-shaped curve with inflection point at around 25–35 °C. Has frequency constant 1.661 MHz⋅mm.[48] Most (estimated over 90%) of all crystals are this variant. Used for oscillators operating in wider temperature range, for range of 0.5 to 200 MHz; also used in oven-controlled oscillators.[49] Sensitive to mechanical stresses, whether caused by external forces or by temperature gradients.
