SG73 Surge Current Thick Film Resistors

KOA Speer SG73 Surge Current Thick Film Resistors are superior to RK73B/RK73H Series in surge dielectric withstanding voltage. The SG73 Series Surge Current Thick Film Resistors from KOA Speer are surface mountable resistors that feature the following markings: SG73P-black three-digit; SG73S-white three-digit on green protective coating; SG73P/S(1E, 1J)- no marking; and SG73P/S (1E)-black coating. KOA Speer SG73 Surge Current Thick Film Resistors use lead-free terminations that meet EU RoHS requirements.
