OUTLINE DIMENSIONS

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 semiconductor. 412DD and 412T 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. Limit Base Emitter current to 15 mAdc.

8. Applicable to all coil voltages. See Base current to turn on.

9. Screened HI-REL versions available. Contact factory.
