Reliability Guidelines

Piezo actuators can be influenced by humidity as well as applied voltage and ambient temperature.
Reliability of Tokin’s multilayer piezoelectric actuators for static usage is represented by MTTF (mean time to failure). The following description is only based on obtained data.

  • DC voltage application
    The MTTFr in actual applications is estimated using equation (1) below with MTTFs observed under accelerated condition as the reference value.
    Reliability Guidelines
  • Pulse voltage application
    Temperature rises when driven by pulse voltage as a result of heating due to dielectric loss of ceramics.
    Therefore the element is less influenced by humidity. The effect is affected by the element shape, pulse waveform and frequency, which cannot be calculated by an equation as in the case of DC voltage application.
    In TOKIN’s testing on the AE0203D08, there was no failure confirmed after 0-150V rectangular pulse wave applied with 500Hz for 500 hours (equivalent to 900 million pulses applied).
    Caution: Physical damage may occur due to ringing phenomenon caused by fixed method of the element and voltage rise speed.

User Guidelines

  • For reliability purposes, avoid handling these piezoelectric actuators (resin-coated) with bare hands, avoid excessive physical shock, and store preferably in a dry atmosphere (below 40% RH) at ordinary temperatures (-5 to +40oC), without vibration. Avoid condensation on the product surface.
  • Center axis of generated displacement to be aligned with the center axis of the load. Axis of the generated displacement to be vertical to the mounting surface.
  • Prevent from being bent, twisted, tensile force applied (including the lead wire), as well as physical shock.
    Reference: Guide for tolerance of twisting and tension
      Reference value Remarks
    Twisting force 3 X 10-1N.m or less For an actuator which generates a force of 800 N (compression resistance)
    Tension 50N or less
  • If the actuator is exposed to high temperature above 100oC or it is used after long storage period (more than 3 months), it should by polarized using the circuit configuration and conditions shown below.
  • Epoxy-based adhesives with high rigidity and minimum thickness are recommended for bonding. Do not form adhesives at the side of actuator.
  • For thermosetting resin, perform polarizing treatment (mentioned above) again after the adhesive is settled.

Electrical connection and handling precautions

Electrical connection :
Connect the red lead wire to the positive (+) terminal of the power supply. Also prevent reverse voltage application.

Handling precautions :
Basically the voltage controls the aimed displacement and generated force.
・In driving, it is also necessary to take ringing due to the resonance or hysteresis of the element itself into consideration. Driving the actuator so that the rising speed is more than 3 times as much as the resonance period to prevent the device from ringing damage.
・In pulse driving, it is further necessary to pay sufficient attention to heat generation due to dielectric loss, charge/discharge current due to the capacitive component and the power output impedance as well.
