12. Caution (Application, Fail-safe)
12-1.Application Limitations
This product, the PKGS type shock sensor, has been designed for hard-disk drive applications,
used in personal computers and consumer audio-visual equipments.
Please contact Murata before using this product in the applications listed below, which require
especially high reliability for the prevention of defects which might directly cause damage to the
third party's life, body or property, or when this product is intended for use in applications other
than those specified in this data sheet. We shall not be liable for any claims on the product in
case it is used in the listed applications below, without contacting us.
(1) Cellular phone (2) Automotive equipment other than the above mentioned
(3) Outside use equipment (4) Aircraft, Avionics equipment (5) Aerospace equipment
(6) Under sea equipment (7) Power plant control equipment (8) Medical equipment
(9) Transportation equipment (vehicles, trains, ships, etc.) (10) Industrial equipment
(11) Traffic signal equipment (12) Disaster prevention / crime prevention equipment
(13) Safety device / system (14) Military equipment (regardless of direct/indirect use)
(15) Applications of similar complexity and/or reliability requirements to the applications listed in
the above.
12-2.Fail-safe
Be sure to provide an appropriate fail-safe function on your product to prevent damage that may
be caused by the abnormal function or the failure of our product.
13. Caution (Handling)
1) This product may be degraded by electrostatic discharge. We would suggest countermeasures
against electrostatic discharge, before handling this product.
2) Please evaluate this product in your product; with it mounted to a Printed Circuit Board (PCB) or
similar. We recommend that this product not be repeatedly mounted on or removed from a PCB
by soldering, because of the possibility of degradation due to excessive heating to this product or
electrostatic discharge (in case electrostatic discharge is not guarded against).
14. Caution (Storage condition and usage environment)
1) Maximum storage period is for 6 months under the condition of 30°C and 70%RH before PCB
mounting. If this product is kept in an especially high humidity environment, the product may
degrade because of decreased insulation resistance value due to such conditions.
2) Please do not store and do not use this product in conditions that differ greatly from atmospheric
pressure, such as a vacuum space, a high mountain, water, and so on. A pressure cooker test is
not applicable for this product.
3) Please do not expose this product to dust, oil, corrosive gas, acid, or alkali. This product may be
degraded if exposed.
15. Caution (Design)
1) Please use a charge amplifier circuit. This specification is only valid for use with charge amplifiers.
For instance, if you use a voltage amplifier circuit that is used with this product, we shall not be
liable for any claims.
2) Please do not apply DC bias voltage to this product, because it causes degradation of insulation
resistance value. Please try to keep minimizing the input bias current at front-end of amplifier circuit
as well.
3) Please thoroughly evaluate this product for noise immunity. Noise, coming from the product (EMI)
and/or generated by signal lines on PCB or other mechanical device (like a spindle motor), may
result in the miss-operation or the non-operation of this product.
4) Please thoroughly evaluate this product in terms of mechanically accelerated transmission system,
because this product may detect unexpected acceleration that is transmitted through PCB and/or
through the frame of your product. Mechanical resonance on your product or individual vibration
frequency of installed components/devices may create mutual interference, and it may result in
incorrect measurement by the sensor.
16.A
Reference only P.14 /15
MURATA MANUFACTURING CO., LTD
5) Please do not apply excessive strain force or shock to this product that deviates from the conditions
in this specification, because mechanical failure or damage could occur.
6) Please thoroughly evaluate this product in your manufacturing if you will use any conformal coating
or potting process. These processes (for instance, in case resin type of material is used) could
result in package breaks, due to heat shrink. Also, humidity that remains inside of the case, may
affect circuit operation due to decreased insulation resistance value.
7) Physical and environmental characteristics for this product are described in this specification.
Please consider these characteristics in evaluating this part in your product.
8) Please carefully design the application’s housing to minimize dew and humidity. An amplifier circuit
would have high impedance, 50M ohm for instance, but this value may decrease under a high
humid environment. Due to this; you may not be able to see the intended performance from your
circuit design, unless you consider theses factors in your product design.
9) Please do not use this product in the presence of radiation rays or cosmic rays.
10) Please do not use this product in the presence of high electromagnetic fields.
11) Please consider the possibility of unexpected output signal-level generated by sharp temperature
change. Please evaluate this product under all expected environmental conditions. We recommend
a fail-safe function to compensate for any unexpected signal levels.
12) Pyroelectric noise may be seen on the output signal of this product, where there is a temperature
variation (delta-t) around the product. Delta-t may likely occur by airflow that is generated by a
cooling fan that is often used in a computer. If your application requires a very small acceleration
resolution, less than 0.1G with 50Hz or less for instance, we would suggest shutting off the airflow
for increased accuracy in sensor detection.
13) This product is very sensitive to bending stress occurring on PCB, therefore please locate the
sensor in an area on the PCB that is unaffected by bending stresses.
16. Caution (Mounting)
16-1 Reflow Soldering
1) Please use the standard footprint as shown in the specification. If you use a different one, we shall
not be liable for any claims.
2) Please follow soldering conditions described in the specification. This product can permanently
stop operating if the piezoelectric characteristic is decreased due to excessive heating.
3) Please follow the recommended washing conditions, as described in the specification.
4) Please make sure to evaluate the soldering condition with this product mounted on your PCB.

1) Please make sure that the final product has been evaluated to all your product’s specifications, with
this product mounted inside.
2) All the items and parameters in this product specification have been prescribed on the premise that
our product is used for the purpose, under the conditions, and in the environment agreed upon
between us. You are requested not to use our product deviating from this product specification.
3) We consider it inappropriate to include any terms or conditions with regard to the business
transactions in the product’s specification, drawing, or other technical document. Therefore, if your
technical document includes any of the above items, such as warranty clause, product liability
clause, or intellectual property infringement liability clause, they will be deemed to be invalid.
