NOTES

1. Relay contacts will exhibit no chatter in excess of 10 µs or transfer in excess of 1 µs.

2. Characteristics shown as “typical” are based on available data and are best estimates. No ongoing verification tests are performed.

3. Unless otherwise specified, parameters are initial values.

4. Parts ordered with no suffix option will be provided with Gold-Plated leads which have a typical plating thickness of 25-40 µin.

5. The slash and characters appearing after the slash are not marked on the relay.

6. Using an operate voltage less than the specified minimum may result in unreliable operation.

7. Relay temperature during soldering shall not exceed 250°C, and reflow temperature shall not exceed 250°C, 3 passes, 1 minute each.
