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.

- Storage condition after opening a moisture-prevention 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).
Mounting and cleaning conditions for surface-mount terminal type relays
When soldering this relay, the following conditions should be observed.
(Recommended condition; Number of reflow: 1 time, Measurement location: terminal temperature)
**==> picture [228 x 136] intentionally omitted <==**
**----- Start of picture text -----**
T3
T2
T1 T1=150 to 180°C
T2=230°C or more
T3=Less than 250°C
t 1=60 to 120 s
t1 t2 t 2=Less than 30 s
Note 1
**----- End of picture text -----**
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.
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.
- (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.
Please refer to **"the latest product specifications"** when designing your product.
