MDCG-4 Features and Benefits

DIMENSIONS (in) mm

Notes

1)

For details on electrical specifications, contact Hamlin.

2)

Contact rating-Product of the switching voltage and current should never exceed the

wattage rating.

Contact Hamlin for additional load/life information.

3)

Operate (inc. bounce) /Release Time-per EIA/NARM RS421A, diode suppressed coil.

4) Pull in Range-Contact Hamlin for tolerances available within this range.

5) Rating Sensitivity-The value at which contact ratings and operating characteristics are

determined. Derating may be required below this value.

6) Storage Temperature-Long time exposure at elevated temperature may degrade

solderability of the leads.
