Rated at 0.063W with +\/-100 ppm\/C TCR, AEC-Q200 qualified. The 20k value is one of the most commonly used resistance values for feedback dividers and bias networks, and the 0402 package enables maximum PCB density in automotive applications.","working_principle":"The RK73H1ETTP2002F operates as a passive thick film resistor:\n\n1. Thick Film Construction: Ruthenium oxide resistive paste on alumina, laser trimmed to +\/-1% tolerance.\n\n2. Popular Value: 20k is a standard E24\/E96 value widely used in voltage divider and bias networks. The 1% tolerance ensures accurate voltage setting in DC-DC converters and regulators.\n\n3. Miniaturized Design: The 0402 package enables the highest PCB density, critical for modern automotive ECUs with ever-increasing component counts.\n\n4. AEC-Q200: Automotive qualification ensures reliability under thermal cycling and vibration.\n\n5. TCR Performance: +\/-100 ppm\/C means the resistance changes at most +\/-2k over a 100C temperature range, maintaining voltage divider accuracy.","pin_description":"\n
