Notes
•
Ask about further value ranges, tighter tolerances and TCR’s
• Power rating depends on the max. temperature at the solder point, the component placement density and the substrate material
• 4-Digit Marking, according to MIL-PRF-55342 (except as noted in Ordering Information table), on top side
