Bourns recommends a symmetrical PCB layout with the resistor centered between the power planes to minimize electromagnetic interference (EMI) and ensure optimal performance.
While the 1140-470K-RC is suitable for high-frequency applications, its performance may degrade above 100 MHz due to parasitic inductance and capacitance. For high-frequency applications, consider using a resistor with a lower inductance and capacitance, such as the Bourns 1206 series.
The 1140-470K-RC is designed to handle high-power pulses, but its pulse-handling capability is limited by its power rating and thermal characteristics. For high-power pulse applications, consider using a resistor with a higher power rating, such as the Bourns 2512 series.
While the 1140-470K-RC meets the requirements for many automotive applications, it may not meet the specific requirements of certain automotive standards, such as AEC-Q200. For automotive applications, consider using a resistor that is specifically designed and qualified for automotive use, such as the Bourns AEC-Q200-compliant resistors.
The 1140-470K-RC is rated for operation up to 155°C, but its performance may degrade at high temperatures. For high-temperature applications, consider using a resistor with a higher temperature rating, such as the Bourns 1206 series, which is rated for operation up to 200°C.
