ORDERING INFORMATION CHECK LIST (CUSTOMS)
Special requirements should be identified in advance, but as a minimum, you should have the following information ready. ELECTRICAL 1. Resistors, by value and tolerance 2. Reference resistor(s) and matching of which resistors to which reference resistors 3. Reference by ratio 4. Absolute temperature coefficient of resistivity 5. Temperature tracking of subordinate resistors to reference resistor(s) 6. Maximum operating voltage 7. Resistor power ratings 8. Operating temperature range Lead (Pb)-free example: WOMCTXXXXA MECHANICAL 1. Maximum allowable seated height (from PC board to top of network) 2. Special marking concerns 3. Schematic pin out of package 4. Specify if lead (Pb)-free
