2) Operating environments
(1) The ZNR is designed to be used indoors. Do not use it exposed outdoors.
(2) Do not use the ZNR in places exposed to temperatures beyond the operating temperature range, such as
places exposed to sunlight and vicinities of heating equipment.
(3) Do not use the ZNR in places exposed to high temperatures and high humidity, such as places exposed directly
to rain, wind, dew condensation, and vapor.
(4) Do not use the ZNR in dusty and salty places and atmospheres polluted by corrosive gases.
3) Processing conditions
(1) Do not wash the ZNR by such solvents(thinner, acetone, etc.) as its exterior resin deteriorates.
(2) Do not apply a strong vibration or shock (by falling, etc.) to the ZNR, cracking to its exterior resin and
element may occur.
(3) When coating the ZNR with resin(including molding), do not use such resin.
(4) Do not bend the ZNR type D lead wires at the position close to its ZNR type D exterior resin, or apply external
force to the position.
(5) When soldering the ZNR lead wires, follow the recommended conditions and do not melt the solder and
insulating materials constituting the ZNR.
✽
1 Soldering iron temperature should not exceed 400 °C and should not be applied for mor than 5 seconds.
✽
2 Profi le be careful because there is a margin of error in the way of measuring.
✽
3 The temperature depend on the size and the package density of the substrate. Therefore, confi rm every kind of the substrate.

4) Long-term storage
(1)Do not store the ZNR under high temperature and high humidity. Store it at a temperature up to 40 °C and at
humidity below 75 %RH, and use it within two years.
Before using the ZNR that has been stored for a long period(two years or longer), confi rm the solderability.
(2) Avoid atmospheres full of corrosive gases(hydrogen sulfi de, sulfurous acid, chlorine, ammonia, etc.).
(3) Avoid direct sunlight and dew condensation.
3. Notices
3.1 In cases that the ZNR is used in equipment(aerospace equipment, medical equipment, etc.) re quir ing extremely
high reliability, ask us for a selection of Part No., and protection coordination, etc. in advance.
3.2 Note that we do not take any responsibility for faults and abnormalities resulting from the use not in conformity with
the contents of entries in the delivery speci cation.
3.3 There is a possibility that the ZNR will unexpectedly cause smoke or ignite because of an abnormal rise of the circuit
voltage and invasion of excessive surge. To prevent that accident from spreading over the equipment and not to ex-
pand the damage, use multiplex protection such as the adoption of frame-retardant materials for hous ing parts and
structural parts.
