With a resistance value of 100 kOhm, \u00b15% tolerance, and \u00b1200 ppm\/\u00b0C temperature coefficient, this resistor is suitable for a wide range of general-purpose applications. The metal glaze thick film deposited on a high-purity alumina ceramic substrate provides excellent heat resistance and environmental stability. The triple-layer electrode construction with nickel barrier and tin plating ensures reliable solder joint formation and long-term stability. AEC-Q200 qualification makes this component suitable for automotive and other demanding environments requiring high reliability.","working_principle":"The RK73B1JTTDD104J operates as a passive thick film resistor:\n\n1. Resistive Element: A metal glaze thick film is screen-printed onto the alumina ceramic substrate and fired at high temperature. The resistance value is determined by the film composition, thickness, and geometric pattern.\n\n2. Triple-Layer Electrode: The inner electrode provides low-resistance contact to the resistive film. The nickel barrier layer prevents solder leaching and migration. The outer tin plating enables reliable solder joint formation.\n\n3. Power Derating: At ambient temperatures up to 70\u00b0C, the full 0.1W power rating is available. Above 70\u00b0C, power decreases linearly to zero at 155\u00b0C.\n\n4. Voltage Limitation: The effective working voltage is the lesser of sqrt(P x R) and the maximum rated voltage of 75V.","pin_description":"\n
