sensing, voltage division and pulse applications
including switching and linear supplies,
instrumentation and power amplifiers
• All welded construction
• Solid metal Nickel-Chrome or Copper-Nickel
alloy resistive element
• Solderable terminations
• Very low inductance
• Lead (Pb)-free version is RoHS compliant
* Pb containing terminations are not RoHS compliant, exemptions may apply
