Revision: 18-Nov-08

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

• 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

2010 and 2512

Notes

Note

• Embossed Carrier Tape per EIA-481-1.2

* Pb containing terminations are not RoHS compliant, exemptions may apply
