Cautions and warnings
Do not operate surge arresters in power supply networks, whose maximum operating voltage
exceeds the minimum spark-over voltage of the surge arresters.
Electromagnetic fields and ionizing radiation may affect the electrical characteristics of the
arrester. The impact of such effects (inductive and capacitive field distortion from adjacent
components) must be avoided by appropriate circuit design measures.
Surge arresters may become hot in the event of longer periods of current stress (burn risk). In the
event of overload the connectors may fail or the component may be destroyed.
If the contacts of the surge arresters are defective, current load can cause sparks and loud
noises.
Surge arresters must be handled with care and must not be dropped.
Do not continue to use damaged surge arresters.
The shown SMD pad dimensions represent a safe way to mount the arrester and are a
recommendation of the manufacturer. During the reflow process it must be assured that no solder
material reduces the insulation distance between the pads below the arrester.
SMD surge arresters should be soldered within 24 month after shipment.
Display of ordering codes for EPCOS products
The ordering code for one and the same EPCOS product can be represented differently in data
sheets, data books, other publications, on the EPCOS 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. Detailed information can be found on the Internet under
