Multilayer Piezoelectric Actuators AE Series Resin Coated Overview Multilayer piezoelectric actuators are ceramic elements used to convert electrical energy into mechanical energy such as displacement or force by utilizing the piezoelectric longitudinal effect. KEMET’s multilayer piezoelectric actuators are produced based on our unique element structure design and piezoelectric ceramic materials with high electrostrictive factors. Compared to conventional piezoelectric actuators, they are smaller in size but can generate higher displacement and force at low voltages. The Resin Coated AE series actuators feature compact size and a wide variety of shapes for applications such as ultra-fine positioning mechanism and drive sources. Benefits • Large generated force of 3,500 N/cm2 • High-speed response: Driving up to about 1/3 of self-resonant frequency (in several ten kHz) • Low power consumption: Can be retained at the leakage current state of 100 μA or less • Very small size: 1/10 or smaller than conventional multilayer actuators Applications Typical applications include positioning, auto focusing of optical systems, pumps, mass-flow valves, vibration source, vibration controls, sensors, image stabilization of DSC, mirror/prism positioning, manipulators, motors and printers.

Although the cause of degradation of insulation has not been clarified, it has been found that the failure rate varies greatly between static uses (DC voltage application) and dynamic uses (pulse voltage application). Like other electrical components, piezoelectric actuators can be affected by humidity as well as applied voltage and ambient temperature. KEMET has added the metal sealed piezoelectric actuators featuring high reliability by eliminating the effects of the ambient atmosphere. This section describes reliability guidelines for static and dynamic usage of the resin coated type actuators. Reliability of our multilayer piezoelectric actuators is represented by MTTF (mean time to failure) in case of static usage. DC Voltage Application The acceleration factors have been obtained empirically for each of the drive voltage, ambient temperature and relative humidity based on many experimental results. The MTTFr in actual applications is estimated using equation (1) below with MTTFs observed under accelerated conditions as the reference value. (1) MTTFr = MTTFs × Av × Ah × At MTTFr : Estimated value MTTFs : Reference value (= 500 hours) Av: Acceleration factor for drive voltage = (150/VR)3.2VR: Actual voltage (V) Ah: Acceleration factor for relative humidity = (90/HR)4.9HR: Actual relative humidity (RH%) TR Actual ambient temperature (ºC) At: Acceleration factor for ambient temperature = 1.5(40 -Tr)/10 The following calculation is made for the case of use at 25°C, 60% RH and 100 V. MTTFr = 500 X (150/100)3.2 X (90/60)4.9 X 1.5(40-25)/10 = 500 X 3.66 X 7.29 X 1.84 ≈ 24,500 hours (2.8 years) Pulse Voltage Application In driving dynamic applications, temperature rises as a result of self-heating allowing the component not to be affected by the humidity, thus extending the operational lifetime. This phenomenon is explained as a result of the humidity factor elimination caused by the selfheating. Since the self-heating value is affected by multiple factors such as the element’s shape, pulse waveform and frequency, it is difficult to estimate the actual rising value. Therefore, the life of the actuator cannot be determined by using an equation, unlike the case of DC voltage applications. When testing the AE0203D08DF part, there was no failure confirmed after 500 hours end of the pulse driving test. (500 Hz, 0 – 150 V rectangular pulse). Users should be careful about the influence of physical damage which can be caused by the fixing method of the element and/or the driving conditions. © KEMET Electronics Corporation • P.O.

Safety designs allowing for failures of electronic components used in the system. In general, failures will occur in electronic components at a certain probability. KEMET makes every effort to improve the quality and reliability of electronic component products. However, it is impossible to completely eliminate the probability of failures. Therefore, when using KEMET’s electronic component products, systems should be carefully designed to ensure the prevention of faulty operation and redundancy in the event of an accident which would result in injury or death, fire, or social damage. Please refer to Precautions when using multilayer piezoelectric actuators for more details of failures. 2. Quality level of various kinds of parts and equipment in which the parts can be utilized as electronic components have a standard quality level unless otherwise specified. KEMET classifies the level of quality of electronic component products into three levels: a standard quality level, a special quality level, and a custom quality level in which a customer individually specifies a quality assurance program. Each of the quality levels has recommended applications. If a user wants to use the electronic parts having a standard quality level in applications other than the applications specified for the standard quality level, they should always consult 26 Multilayer Piezoelectric Actuators Vol.08 a KEMET representative before using the electronic parts. ●All specifications in this catalog and production status of products are subject to change without notice ●Please request for a specification sheet for detailed product data prior to the purchase. ●Before using the product in this catalog, please read "Precautions" and other safety precautions listed © KEMET Electronics Corporation • P.O.

Should any of these products come under the category of strategic goods or services (according to Japan’s foreign trade and foreign exchange regulations), the sender must obtain an export license from the Japanese Government before said products can be exported outside Japan. Precautions to be taken when using Multilayer Piezoelectric Actuators (Please read these precautions before using our products) 1. Before using or designing a system using our products, read the precautions and specifications (such as level of quality) for the products you intend to use. 2. The main failures with multilayer piezeoelectric actuators are deterioration of insulation resistance, short-circuit, and open-circuit. Before using the products, design systems carefully to ensure redundancy, prevention of the spread of fire, and prevention of faulty operation allowing for the occurrence of failures. 3. Use the products after checking the working conditions and rated performance of each multilayer piezoelectric actuator series. Selection of AE series (resin coated type) or ASB series (metal sealed type) should be based on the intended working temperature and humidity. © KEMET Electronics Corporation • P.O.
