Notes: *1. This value can change due to the switching frequency, environmental conditions, and desired reliability level, therefore it is recommended to check this with the
actual load.
*2. Wave is standard shock voltage of
±1.2×50µs
according to JEC-212-1981
*3. The upper limit of the ambient temperature is the maximum temperature that can satisfy the coil temperature rise value. Refer to Usage, transport and storage

NOTES
1. PC board patterns for 2 coil latching
types
When applying relays in power supply
operation circuits for finished products
regulated by the Electrical Appliance and
Material Safety Law, use the pattern
shown below.
2. Soldering should be done under the
following conditions:
1)
250°C
482°F
within 10s
300°C
572°F
within 5s
350°C
662°F
within 3s
2) For automatic cleaning, the boiling
method is recommended. Avoid
ultrasonic cleaning which subjects the
relays to high frequency vibrations, which
may cause the contacts to stick.
It is recommended that a fluorinated
hydrocarbon or other alcoholic solvents
be used.
3. When using, please be aware that
the a contact and b contact sides of 1
Form A and 1 Form B types may go on
simultaneously at operate time and
release time.
