Power Wirewound Resistors
(AK, P & C Series)
FEATURES:
- Resistance Tolerance: 5%, 3%, 1% std
(Accuracies available to .05%) - Standard Resistance Range: .1Ω to maximum listed.
- Temperature Coefficient: 90ppm/°C less than 1Ω ; 50 ppm/°C 1 Ω to 10Ω ; 30 ppm/°C 10Ω to 100Ω ; 20 ppm/°C 100 Ω and above.
- Short Term Overload: 5 seconds at 5 times rated power.
- Operating Range: -55°C to + 250°C (U Rating) or +350°C (V Rating)
- Covering: Flame Retardant Silicone (Molded & Coated)
- Windings: Space wound on Ceramic or Alumina Oxide Cores.
Non-inductive windings are available & identified by adding an "N" in front of the style number.
- Divide maximum resistance by 2 for non-inductive windings.
- "U" and "V" wattage ratings and derating curves are based on MIL-PRF-26 characteristics. "V" ratings are intended for 5% tolerance units, and result in operation at a hotspot of approximately 350°C; "U" ratings govern 3% through .1% tolerances and result in a hotspot of approximately 250°C
- RoHS compliant, Pb-Free construction available.
