GENERAL NOTES
1. Relay contacts will exhibit no chatter in excess of 10 µsec or transfer in excess of 1
µsec.
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. For reference only. Coil resistance not directly measurable at relay terminals due to
internal series diode, 421DD only.
5. Unless otherwise specified, relays will be supplied with either gold-plated or solder-
coated leads.
6. The slash and characters appearing after the slash are not marked on the relay.
7. Screened HI-REL versions available. Contact factory.
