Rated at 0.063W with +\/-100 ppm\/C TCR, AEC-Q200 qualified. The E96 2.20k value with 1% tolerance is ideal for precision feedback dividers and voltage setting in space-constrained automotive and IoT applications.","working_principle":"The RK73H1ETTP2201F operates as a passive thick film resistor:\n\n1. Thick Film Construction: Ruthenium oxide resistive paste screen-printed on alumina, laser trimmed to +\/-1% tolerance.\n\n2. E96 Value: The 2.20k is an E96 series value providing fine resistance steps for precision voltage divider design.\n\n3. Miniaturized Design: The 0402 package is the smallest commonly used resistor size, enabling highest PCB density.\n\n4. AEC-Q200: Despite the small size, automotive qualification ensures reliability under thermal cycling and vibration.\n\n5. TCR Performance: +\/-100 ppm\/C ensures resistance drift stays within +\/-1% over a 100C temperature range.","pin_description":"\n
