NOTES
1. For cautions for use, please read
“GENERAL APPLICATION
GUIDELINES” on page B-1.
2. Soldering should be done under the
following conditions:
1) Preheating: Within 120°C 248°F and
within 120 seconds
2) Soldering iron: 260°C±5°C
500°F±41°F and within 6 seconds
3. External magnetic field
Since DK relays are highly sensitive
polarized relays, their characteristics will
be affected by a strong external magnetic
field. Avoid using the relay under that
condition.

3. Remove the relay, applying force in the
direction shown below.

greater than necessary force is applied at
the socket hooks, deformation may alter the
dimensions so that the hook will no longer
catch, and other damage may also occur.
2. It is hazardous to use IC chip sockets.
