RF73
fusing flat chip resistor
EU
features
• Anti-leaching nickel barrier terminations
• Suitable for flow and reflow soldering
• Performs like RK73 under normal conditions
• Fuses when overloaded
• Marking: Black three-digit on brown protective coating
• Products with lead-free terminations meet EU RoHS
requirements. Pb located in glass material, electrode
and resistor element is exempt per Annex 1, exemption
5 of EU directive 2005/95/EC
