NEW
RK73G-RT
flat chip resistor
(ultra precision grade, anti sulfuration)
EU
features
• Excellent anti-sulfuration characteristic due
to using high sulfuration-proof inner top electrode material
• Metal-glaze thick film resistor for surface mounting
• High precision resistor with T.C.R. ±50x10^-6/K
and tolerace ±0.5%
• Suitable for both flow and reflow solderings
• Marking: 1E: no marking on black protective coating
1J, 2A, 2B: white on dark blue protective coating
• Products with lead-free terminations meet EU RoHS
requirements. EU RoHS regulation is not intended for
Pb-glass contained in electrode, resistor element and glass.
• AEC-Q200 Qualified
