SHOULD NOT BE RELIED UPON AS BEING ACCURATE FOR ANY PARTICULAR PURPOSE
Product performance may be affected by the application that the part is used for.
Upon request Hamlin will assist purchasers by providing information specific to a particular application.
Hamlin disclaims all liability whatsoever for any purchaser’s reliance upon the information
contained in this data sheet without further consultation with Hamlin’s authorised representatives.
Notes:- 1) Contact Rating. Product of the switching voltage and current must never exceed the wattage rating. Contact Hamlin for additional load/life information.
2) Storage Temperature. Long term exposure at elevated temperature may degrade solderability of the leads.
3) Operate (including bounce) /Release Time. Tested per EIA/NARM RS421A with diode suppressed coil.
4) Rating Sensitivity. The value at which the contact ratings and operating characteristics are determined. De-rating may be required below this value.
