Power Metal Strip® Flip Chip (Extended Range)
Patents Pending
FEATURES
• SMD alternative for low power leaded
wirewound resistors
• Excellent stability in different environmental
conditions (< 0.5 % change in resistance)
• Superior overload and pulse handling capability
as compared to thin film (as much as 2 x better)
• Low TCR, down to ± 15 ppm/K
• Low noise: < 0.01 μVRMS/V
• Very low inductance: < 0.08 μH
• Voltage coefficient: < 0.00001 %/V (< 0.1 ppm/V)
• Compliant to RoHS Directive 2002/95/EC
Notes
* Pb containing terminations are not RoHS compliant, exemptions may apply

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.
