The 394 marking code (39 \u00d7 10\u2074 = 390k\u03a9) represents a standard E24 value commonly used in high-impedance bias and timing circuits. The 0.031W power rating is sufficient for the very low currents typical at 390k\u03a9 resistance (e.g., 25\u03bcA at 10V). The compact 0402 footprint is ideal for high-density portable device designs where board space is at a premium.","working_principle":"The ERJ2GEJ394X uses a metal glaze thick film resistive element deposited on an alumina substrate, laser-trimmed to 390k\u03a9 with \u00b15% tolerance. The high resistance value is achieved through a combination of high-resistivity thick film paste formulation and a long, narrow resistive path geometry. The three-layer electrode (Ag\/Ni\/Sn) provides reliable solder joints. The 25V voltage rating reflects the maximum working voltage for the 0402 ERJ-2GE series, which is lower than the 50V rating of the 0603 and larger packages.","pin_description":"\n
