AEC-Q200 qualified for automotive applications requiring higher power dissipation in a compact footprint.","working_principle":"The CRCW1210845RFKEAHP operates as a passive thick film resistor:\n\n1. High Power Design: The HP variant uses optimized thick film composition and substrate thermal design to achieve 0.75W rating in a 1210 package, 50% higher than the standard 0.5W. This is achieved through improved heat dissipation from the resistive element to the PCB.\n\n2. Resistive Element: Cermet thick film on alumina substrate, laser-trimmed to 845 Ohm E96 value. The 1210 package provides sufficient area for the power rating.\n\n3. Power Derating: Full 0.75W up to 70\u00b0C ambient, derating linearly to zero at 155\u00b0C.\n\n4. Voltage Rating: 200V maximum working voltage provides adequate margin for power supply and motor drive applications.","pin_description":"\n
