Notice
1. Use this co mponent within operating tempera ture range. It might n ot be
satisfied with electrical specificatio n without operating te mperature range.
When it is used less tha n -20ºC or more than +70ºC, it mig ht be a cause of
degradation or destruction of the component. Even if it endures during a short
time, it causes degradation of qualification.
2. When soldering iron is used, solder with the temperature at the tip of soldering
iron: 350ºC max., the time of soldering: 10 seconds max., the power of
soldering iron: 30W max..
3. Notice that the allowed time of soldering with soldering iron is accumulated
time, when soldering is repeated.
4. As rapid temperature c hange for cleaning af ter reflow soldering might be a
cause of destruction clean this component after confirming that temperature of
this component goes down to room temperature.
5. Confirm that there are not any influence for qualification to this component in
mounting on PCB when this component is cleaned.
6. As it might be a cause of degradation of destruction to apply static electricity to
this component, do no t apply st atic electricity or excessive volt age while
assembling and measuring. And do not transpo rt this component with bare
hand.
7. As it might be a cau se of degrada tion or de struction to apply D.C. volt age
between each terminal, apply D.C. voltage 7.5V max. in actual circuit.
Note
1. This specification specifies the quality of this component as a single un it. Make
sure that this component is evaluate d and confir med against this sp ecification
when it is mounted to your products.
2. The information cont ained herein may be changed with out prior no tice. It is
therefore advisable to contact Japan Radio Company before proceeding with the
design of equipment incorporating this product.
3. The products are designed to be used with ordinary electronic equipment (dat a
and communications equipment, office equipment, audio-video equipment ,
measuring instruments, etc). Jap an Radio Co mpany does not assu me any
liability for the case u sing the pr oducts with the application requir ed high
reliability or safety extremely (such as space equipment, sea-bottom equipment,
