Multilayer Piezoelectric Actuators
ASB Series Metal Sealed 85°C
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 displacements and forces at low voltages.
The ASB Metal Sealed 85°C series actuators are less impacted
by ambient humidity due to insulation from the atmosphere. As
a result, long operational life and high performance have been
attained which are ideal for use in various high reliability applications
such as semiconductor device production equipment and optical
communication equipment.
Benefits
• High reliability: Realization of MTTF = 36,000 hours at
85°C and 100 V
• Built-in pre-load mechanism and mounting attachments
allowing for easier installation
• Accurate nanometer positioning
• Minimum mechanical abrasion
• Large generated force of 800 N
• Long operational life
• RoHS/REACH compliant
Applications
Typical applications include fine adjustment of various X-Y table steppers, mirror/prism positioning, linear motors, fluid flow control valve
drive, vibration source and manipulators.

Multilayer Piezoelectric Actuators – ASB Series Metal Sealed 85°C
Reliability
The majority of failure modes on multilayer piezoelectric actuators are short-circuits due to degraded insulation. 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 metal sealed type actuators. Reliability of our multilayer
piezoelectric actuators is represented by MTTF (mean time to failure) in case of static usage. The number of repetitions is considered to
represent the reliability in the case of dynamic usage.
DC Voltage Application
MTTFr of the metal sealed type under the actual operating conditions is calculated from the reference MTTFs and the acceleration
factor as it is in the case of the resin coated type. However, since the internal element is sealed from the atmosphere, it is not affected
by the atmospheric humidity. Therefore, equation (1) below is used.
(1) MTTFr = MTTFs × Av × At
MTTFr : Estimated value
MTTFs : Reference value (= 36,000 hours)
Av: Acceleration factor for drive voltage = (100/VR)2 VR: Actual operating voltage (V)
TR Actual ambient temperature (ºC)
At: Acceleration factor for ambient temperature = 1.5(85 -Tr)/10
The following calculation is made for the case of use at 25°C, and 150 V.
MTTFr = 36,000 X (100/150)2 X 1.5(85-25)/10
= 36,000 X 0.44 X 11.3
≈ 179,000 hours (20.4 years)
Pulse Voltage Application
Similarly to the resin coated type, it is extremely difficult to estimate reliability for the metal sealed type products by using an equation.
In KEMET’s testing on the ASB170C801NP0, there was no failure confirmed up to 1,000 hours (equivalent to 100 million pulses applied)
under the conditions below:
Temperature: 85 ±2°C
Humidity: 90 to 95% RH
Load: 200 N to 500 N (20 kgf to 50 kgf)
Drive voltage waveform: rectangular wave, 30 Hz, 0 to 100 V, duty ratio at 30%

• Install the actuator so that the center axis of the generated displacement is aligned with the center axis of the load.
• Select the mounting bracket (female thread type or flange type) according to the mounting method and install the element utilizing the
bracket.
• Fix the element securely so that the generated force and displacement cannot be deteriorated.
• Connect the driven item at the displacement generating end after securing the mounting portion, so that it avoids unnecessary stress
applied at the time of installation.
• Though this product is designed to apply a compresive force to the internal element by the metal case, avoid any usage that can
cause bending, twisting, or tension force when the device is in use.
Driving Method
• Connect the red lead wire to the positive (+) terminal of the power supply. Also prevent reverse voltage application.
• In driving applications, it is necessary to take consideration of hysteresis, ringing, creep, and other similar phenomenons. For pulse
driving, it is also necessary to be aware of self-heat generation, charge/discharge current, and the power supply’s impedance.

1. 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.

Multilayer Piezoelectric Actuators – ASB Series Metal Sealed 85°C
Precautions cont’d
Standard Quality Level: Computers, office automation equipment, communication equipment, measuring instruments, AV
equipment, household electrical appliances, machine tools, personal equipment and industrial robots.
Special Quality Level: Transportation equipment (automobiles, railways, shipping), traffic signals, disaster prevention/crime
prevention systems, a variety of safety devices and medical equipment which are not directly intended for life-support purposes.
Custom Quality Level: Equipment for airplanes, aerospace equipment, nuclear power control systems, medical equipment
and apparatus or systems for life-support purposes.
Unless otherwise specified, the quality level of KEMET’s electronic component products shown in documents such as catalogs,
datasheets or technical books are the standard quality level.
3. This manual is subject to change without notice. The content of this manual is based on data which is correct as of December,
2014 and they may be changed without notice. If our products are used for mass-production design, please consult with a member
of our company’s sales staff.
4. Reprinting and copying of this manual without prior written permission from KEMET Electronics Corporation is not permitted.

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.
