The ERJ series resistors by Panasonic are automotive-grade high-precision thick film chip resistors. They feature a metal glaze thick film resistive element and a three-layer electrode design, ensuring high reliability. These resistors are available in standard EIA case sizes including 01005, 0201, 0402, 0603, 0805, 1206, 1210, 1812, 2010, and 2512, and are characterized by their small size and low weight. They are rated for a maximum power of 1W and offer tolerance options of ±0.5% and ±1%. The temperature coefficient (TCR) options include ±50, ±100, ±200, and ±300 ppm/°C. Operating temperature ranges are -55°C to 125°C and -55°C to 155°C. 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.
