Which center frequency produces the thinnest crystal?

Which center frequency produces the thinnest crystal?

• A. 10 MHz center frequency
• B. 15 MHz center frequency
• C. 7 MHz center frequency
• D. 5 MHz center frequency

Answer: (B)

Crystal thickness and resonant frequency are inversely related. For a quartz resonator, achieving a higher center frequency requires a thinner crystal plate because the frequency is roughly proportional to how rapidly the plate vibrates, which depends on its thickness. So, among the given options, the center frequency with the highest value uses the thinnest crystal. That makes it the thinnest among the choices.
