Part Numbering System (Notes 4 & 5)

NOTES:

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

2. “Typical” characteristics are based on available data and are best estimates. No on-going verification tests are performed.

3. Unless otherwise specified, parameters are initial values.

4. Unless otherwise specified, relays will be supplied with solder-coated leads.

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