- Intervals between terminals is measured at A surface level. ## **NOTES** ## **1. Soldering** Max. 350°C 662°F (solder temperature), within 3 seconds (soldering time) The effect on the relay depends on the actual PC board used. Please verify the PC board to be used. ## **2. Usage, transport and storage conditions** - 1) Ambient temperature, humidity, and atmospheric pressure during usage, transport, and storage of the relay: (1) Temperature: –40 to +85°C –40 to +185°F (Standard type) - –40 to +125°C –40 to +257°F (High heatresistant type) - (2) Humidity: 2 to 85% RH (Avoid freezing and condensation.) - (3) Atmospheric pressure: 86 to 106 kPa The humidity range varies with the temperature. Use within the range indicated in the graph below.
