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.
