Notes: *1. Depends on connection conditions. Also, this does not guarantee repeated switching. We recommend that you confirm operation under actual conditions.
*2. 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.
*3. The upper operation ambient temperature limit is the maximum temperature that can satisfy the coil temperature rise value. For details, please refer to the “Automotive
Relay Users Guide”.
Please inquire our sales representative if you will be using the relay in a high temperature atmosphere (110°C).

GUIDELINES FOR USAGE
For general cautions for use, please refer to the "Automotive Relay Users Guide".
Precautions when using CN-M relays
Usage, transport and storage conditions
1) Ambient temperature,humidity, and air pressure during
usage,transport of the relay
(1) Temperature: -40 to +85°C (standard type)
-40 to +110°C (high heat-resistant type)
(2) Humidity:
5 to 85% RH (standard type)
2 to 85% RH (high heat-resistant type)
(Avoid icing and condensation)
(3) Air pressure: 86 to 106 kPa
The humidity range varies with the temperature. Use within the
range indicated in the graph.
ounting and cleaning conditions for surface-mount terminal
M
type relays
When soldering this relay, the following conditions should be
observed.

Temperature profile indicates the temperature of the soldered
part (Note 1) of terminals on the surface of the PC board,
however, for other areas such as the surface of relay case,
make a setting so that you do not exceed the recommended
conditions.
* The temperature of the relay exterior and interior may be
extremely high depending on the component density on the
board, the heating method of the reflow oven or circuit board
type.

torage condition after opening a moisture-prevention
S
package
(1) After opening a moisture-prevention package, use the item
as soon as possible (within 3 days under an environment
of Max. 30°C, Max. 70% RH).
(2) If products are not used within 3 days after opening a
moisture-prevention package, store them in a humidity
controlled desiccator or in a storage bag with silica gel.
Other cautions of reflow soldering
(1) Reflow performance may be affected if you carry out
soldering in a way that exceeds the recommended conditions.
If you need to exceed the recommended conditions when
soldering, please inquire our sales representative before
using in an application.
(2) Please confirm the heat stress of relay by using actual
board because it may be changed by board condition or
manufacturing process condition.
(3) Solder creepage, wettability, or soldering strength will be
affected by the changing of soldering condition or used
solder type. Please check them under the actual production
condition in detail.
(4) Avoid cleaning (ultrasonic cleaning, boiling cleaning, etc.)
and coating in order to prevent negative impacts on relay
characteristics.
Please refer to "the latest product specifications"
when designing your product.
