This relay is a surface-mounted model
with excellent high-frequency proper-
ties. In addition, it can use a microstrip
line in the base circuit design which
spares the labor of machining the base.

NOTES
1. Coil operating power
Pure DC current should be applied to the
coil. The wave form should be rectangu-
lar. If it includes ripple, the ripple factor
should be less than 5%.
However, check it with the actual circuit
since the characteristics may be slightly
different. The nominal operating voltage
should be applied to the coil for more
than 10 ms to set/reset the latching type
relay.
2. Coil connection
When connecting coils, ref er to the wiring
diagram to prevent mis-operation or mal-
function.
3. External magnetic field
Since RA relays are highly sensitive po-
larized rela ys , their char acteristics will be
affected by a strong external magnetic
field. Avoid using the relay under that
condition.
4. Cleaning
For automatic cleaning, the boiling meth-
od is recommended. Avoid ultrasonic
cleaning which subjects the rela ys to high
frequency vibrations, which may cause
the contacts to stick.
It is recommended that alcoholic solvents
be used.
5. Soldering
Manual soldering shall be performed un-
der following condition.
Tip temperature: 280°C to 300°C .536°F
to 572°F
Wattage: 30 to 60W
Soldering time: within 5s
In case of automatic soldering, the follo w-
ing conditions should be observed
1) Position of measuring temperature
2) IR (infrared reflow) soldering method
Temperature rise of relay itself may vary
according to the mounting level or the
heating method of reflow equipment.
Therefore, please set the temperature of
soldering portion of relay terminal and
the top surface of the relay case not to
exceed the above mentioned soldering
condition.
It is recommended to check the tempera-
ture rise of each portion under actual
mounting condition before use.
The soldering earth shall be performed
by manual soldering.
