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 µV_rms/V
• Voltage coefficient: < 0.00001 %/V
(< 0.1 ppm/V)
• Very low inductance: < 0.08 µH

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
