Anti-Sulfur Resistors Panasonic Anti-Sulfur Thick Film Chip Resistors in standard, wide terminal, and array types provide excellent resistance to sulfuration by using an Ag-Pd based inner electrode. These Panasonic Anti-Sulfur Resistors ensure high reliability by utilizing metal glaze thick film resistive elements and three layers of electrodes. ERJ-U, ERJ-C1, and EXB-U devices are suitable for use in automotive, industrial, factory automation, and power supply applications that may be subject to a high-sulfur environment. These Panasonic resistors are ideal for use in a variety of applications, including ECU, navigation systems, DC-DC power supplies, notebook PCs/desktop PCs/servers, and memory modules (SSD, DDR).
