RS73-RT Chip Resistors

KOA Speer RS73-RT Chip Resistors have excellent anti-sulfuration characteristics due to using a high sulfuration-proof inner top electrode material and a metal-glaze thick film resistor for surface mounting. The RS73-RT is a high-precision resistor with TCR down to 25ppm and tolerance as tight as ±0.1%. These resistors are highly reliable, with a ∆R of ±0.2% and ±0.5% in the reliability test. Suitable for flow and reflow solderings, these chip resistors have lead-free terminations that meet EU RoHS requirements. KOA Speer RS73-RT Chip Resistors are AEC-Q200 tested.
