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”.

## **GUIDELINES FOR USAGE** **For general cautions for use, please refer to the "Automotive Relay Users Guide".** ## **Precautions when using CB relays** Soldering Solder temperature: 350°C, within 3 sec (in a solder bath) The effect on the relay depends on the actual PC board used. Please verify the PC board to be used. 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 +125°C (High heat-resistant type) - (2) Humidity: 2 to 85% RH (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. - **[Temperature and humidity range for usage, transport, and** ## **storage]** **==> picture [178 x 138] intentionally omitted <==** **----- Start of picture text -----**
