With tolerances as tight as \u00b10.05% and TCR values down to \u00b110 ppm\/K, the CMF series delivers superior performance in compact footprints ranging from 0402 to 2040. The 46.4 k\u03a9 variant with \u00b10.1% tolerance and \u00b115 ppm\/K TCR is specifically designed for precision signal conditioning, voltage division, and feedback networks in industrial and medical electronics.","working_principle":"The CMF0603 resistor utilizes a sputtered thin film resistive element on a high-purity ceramic substrate. The resistance layer is deposited with precise thickness control to achieve the target resistance value, then laser-trimmed for exact calibration. A protective passivation layer covers the resistive element to ensure long-term stability against environmental factors. The nickel barrier layer beneath the tin termination prevents solder leaching and maintains contact integrity during reflow soldering. Under operating conditions, the thin film element exhibits minimal drift due to its homogeneous crystalline structure, ensuring the \u00b10.1% tolerance and \u00b115 ppm\/K TCR are maintained over time and temperature variations.","pin_description":"
