RK73-RT
flat chip resistors (anti-sulfuration) features • Excellent anti-sulfuration characteristic due to using high sulfuration-proof inner top electrode material • Excellent heat resistance and weather resistance are ensured by the use of metal glaze thick film • High stability and high reliability with the triple-layer structure of electrode • Marking: Z1E: Green protective coating RK73B1E ~ W3A, RK73Z1J ~ W3A: Black protective coating RK73H1E ~ W3A: 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: 0402 (1E), 0603 (1J), 0805 (2A), 1206 (2B), 1210 (2E), 2010 (W2H), 2512 (W3A) dimensions and construction
