This paper introduces the main points of YAGEO's two series of resistance selection, as well as a variety of model specifications table, hoping to help engineers better choose the appropriate resistance, YAGEO as an internationally renowned electronic components supplier, its automotive patch resistance AC0201 and AC0402 series has excellent performance, and is widely used.
AC0201 patch resistor series
AC0201 series is a supercompact vehicle patch resistor from YAGEO with a size of 0201 (0.6mm x 0.3mm). Despite its small size, AC0201 series resistors have excellent electrical performance, the main feature of this series of resistors is a small tolerance range, can meet the requirements of high precision resistance value circuit applications, the temperature coefficient of this series of resistors is low, can maintain a stable resistance value in a wide temperature range, optimize the material and process. The AC0201 series resistors can still maintain stable performance in harsh on-board environments. Therefore, when selecting the type, engineers need to consider the resistance value, tolerance range, temperature coefficient and packaging form of the resistance and other parameters, but also according to the actual needs of the circuit to select the appropriate resistance value range and packaging form to ensure the normal operation of the circuit.
AC0402 patch resistor series
AC0402 series is another YAGEO automotive patch resistor, its size is 0402 (1.0mm x 0.5mm), compared with AC0201 series, AC0402 series resistor is slightly larger, but also has excellent electrical performance, due to the relatively large volume, AC0402 series resistor can withstand higher power, Suitable for circuit applications requiring large currents, this series of resistors can maintain stable performance over a long period of use, reducing the frequency of maintenance and replacement. The AC0402 series resistors are suitable for a variety of on-board electronic devices such as ECUs, sensors, control systems, etc. In the selection, engineers need to comprehensively consider the resistance value, power tolerance, temperature coefficient and packaging form of the resistor and other parameters, but also need to choose the appropriate resistance value range and packaging form according to the actual application scenario to ensure that the resistor can meet the performance requirements of the circuit.
