The ERJ-6GEYJ392V is a general-purpose thick film chip resistor with a resistance of 3.9 kΩ and a tolerance of ±5%. This 0805 surface-mount device is part of the ERJ6G series and has a power rating of 0.125 W at 70°C, with a limiting element voltage of 150 V. It features a temperature coefficient of resistance (TCR) of ±200 ×10⁻⁶/°C and operates across a temperature range of -55°C to +155°C. Constructed with a metal glaze thick film resistive element and three-layer electrodes for high reliability, it is suitable for both reflow and flow soldering processes. Its small size and compatibility with automated placement machines make it ideal for a wide range of general-purpose electronic applications.
