The ERJ-6GEYJ121V is a 120 Ω thick film chip resistor in an 0805 package, part of the AEC-Q200 compliant ERJ6G series. It features a power rating of 0.125 W at 70°C, a resistance tolerance of ±5%, and a limiting element voltage of 150 V. This resistor is constructed with a reliable metal glaze thick film resistive element and operates over a wide temperature range of -55°C to +155°C. With a temperature coefficient of resistance of ±200 ×10⁻⁶/K, it provides stable performance. Its small size, reliability, and compatibility with both reflow and flow soldering make it well-suited for a variety of automotive and general-purpose electronic applications.
