RK73-RT Datasheet | KOA

RK73-RT resistors .. 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 - Suitable for both flow and reflow solderings - Marking: Black protective coat on RK73B, RK73Z1J, 2A, 2B, 2E, W2H, W3A Blue protective coat on RK73H Green protective coat on RK73Z1E - Products with lead-free terminations meet EU Ro HS requirements.
