The MCWR08X392 JTL from Multicomp is a MCWR08 series thick film chip resistor. The resistor is constructed in a high grade ceramic body (aluminium oxide). Internal metal electrodes are added at each end and connected by a resistive paste that is applied to the top surface of the substrate. It is used in electrical equipment, EDP, computer and telecom applications.
