Important notes at the end of this document.
Cautions and warnings
The piezo component has to be operated in a dry, non-reducing, open environment and atmosphere
which must not contain any chemical vapors or substances.
To prevent damages on the piezo component, tensile stresses must be avoided under all driving
conditions.
We expressly point out that in case of non-observance of the aforesaid notes, in particular due to
reasons attributable to chemical vapors, a malfunction of the piezo sample or failure before the end of
their usual service life cannot be completely ruled out, even if they are operated as specified.
Depending on the individual application, piezo samples are electrically connected to voltages and
currents, which are potentially dangerous for life and health of the operator. Installation and operation
of piezo sample have to be done only by authorized personnel. Ensure proper and safe connections,
couplers, and drivers.
Caution:
Piezo component are highly efficient charge storing capacitors. Even when they are
disconnected from a supply, the electrical energy content of a loaded actuator can be high and is held
for a long time. Always ensure a complete discharging of an actuator (e.g. via a 10 k
resistor) before
handling. (Do not discharge by simple short-circuiting, because of the risk of damaging the ceramic.)
Electrical charges can be generated on disconnected actuators by varying load or temperature.
Caution:
Discharge an actuator before connecting it to a measuring device/electronics, when this
device is not sufficiently voltage proofed.

Display of ordering codes for TDK Electronics products
The ordering code for one and the same product can be represented differently in data sheets, data books,
other publications, on the company website, or in order-related documents such as shipping notes, order
confirmations and product labels.
The varying representations of the ordering codes are due to
different processes employed and do not affect the specifications of the respective products
.
