2) Static capacitance
Mechanical Characteristics

Solderability
Lead Wire Pull Strength
Vibration
The piezo electric diaphragm should be clamped at a node point (as shown in the following figure) to be free from any
mechanical stress. Measure its resonant frequency and resonant impedance by using a vector impedance analyzer or
equivalent.
When the input frequency is swept within 100 Hz to 9 KHz, the resonant frequency is defined as the frequency where
the impedance shows minimum value. This impedance should be the resonant impedance.
The electrostatic capacitance should be measured at 1 KHz by using an L.C.R. meter (ex. HP4194A(H.P.)) or
equivalent. The part should be clamped in the same way as the measurement or resonant frequency / resonant
impedance mentioned above.

Test Condition
Stripped wires of lead wires are immersed in
rosin for 5 seconds and then immersed in
solder bath of 270 ±5°C for 3 ±0.5 seconds.
The horizontal force of 3.0N (0.306kg) should
be applied to the double lead wire for 30 sec.
The diaphragm should be measured after
applying a vibration amplitude of 1.5 mm with
10 to 55 Hz band of vibration frequency to each
of the 3 perpendicular directions for 2 hours.

Evaluation Standard
90% min. of the stripped wires
will be wet with solder.
(Except the edge of the terminal)
No damage or cutting off.
The value of the resonant
frequency should be ±10% of the
initial measurements.
Electrostatic capacitance should
be ±20% compared with the initial
measurement. The resonant
impedance should be 2000Ω
max.
