SG731JRT Datasheet, PDF (1/2 Pages) KOA Speer Electronics, Inc. – surge current flat chip resistors (anti-sulfuration)

SG73-RT
surge current flat chip resistors
(anti-sulfuration)
EU
features
• Excellent anti-sulfuration characteristic
due to using high sulfuration-proof inner
top electrode material
• Superior to RK73 series chip resistors
in pulse withstanding voltage
• Suitable for both flow and reflow soldering
• Marking: White three-digit on wine red protective coat
• 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
