Notice
1. Use this component within operating temperature range. It might not be
satisfied with electrical specification without operating temperature range.
When it is used less than -10ºC or more than +60ºC, it might 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 change for cleaning after 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 not apply static electricity or excessive voltage while
assembling and measuring. And do not transport this component with bare
hand.
7. As it might be a cause of degradation or destruction to apply D.C. voltage
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 unit.
Make sure that this component is evaluated and confirmed against this
specification when it is mounted to your products.
2. The information contained herein may be changed without prior notice. 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
(data and communications equipment, office equipment, audio-video
equipment, measuring instruments, etc). Japan Radio Company does not
assume any liability for the case using the products with the application
required high reliability or safety extremely (such as space equipment,
sea-bottom equipment, medical equipment etc). When intending to use any
our product please contact our sales representatives in advance.
