The ERJ series resistors are automotive-grade, precision thick film chip resistors manufactured by Panasonic. They feature high reliability due to their metal glaze thick film resistive element and three-layer electrode design. These resistors are available in standard EIA case sizes, including 01005, 0201, 0402, 0603, 0805, 1206, 1210, 1812, 2010, and 2512, and are known for their small size and lightweight construction. They are rated for a maximum power of 1W and come in tolerance options of ±0.5% and ±1%. The temperature coefficient (TCR) ranges from ±50 to ±300 ppm/°C, with operating temperature ranges extending from -55°C to 125°C or -55°C to 155°C, depending on the specific model. These resistors comply with IEC 60115-8, JIS C 5201-8, and EIAJ RC-2134B standards, and are suitable for both reflow and flow soldering processes. They are certified as automotive-grade and meet the AEC-Q200 standard.
