GENERAL NOTES
PERFORMANCE CURVES (Note 2)
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. Relays can be supplied with a spacer
pad. See appendix.
