When the input frequency is swept within 100 Hz to 7 kHz, the resonant frequency is defined as the frequency where the impedance shows the minimum value, and this impedance shall be the resonant impedance. Static Capacitance The electrostatic capacitance shall be measured at 1.0 kHz by using LCR meter HP4194A(H.P.) or equivalent. This part shall be clamped in the same way as the measurement of resonant frequency and resonant impedance as mentioned above. cuidevices.com Additional Resources: Product Page | 3D Model CUI DEVICES | MODEL: CEB-27D44 | DESCRIPTION: PIEZOELECTRIC DIAPHRAGM date 08/05/2022 | page 3 of 3 REVISION HISTORY rev. description date 1.0 initial release 07/28/2006 1.01 brand update 05/13/2020 logo, datasheet style update 08/05/2022 1.02 The revision history provided is for informational purposes only and is believed to be accurate.
