The AC0402JR-071M1L is a thick film resistor manufactured by Yageo. It is a surface mount device constructed from a thin film of metal and ceramic, and is designed for use in critical applications requiring high reliability and precision. This part features an ultra-low temperature coefficient of maximum ±100 ppm/°C, and a wide resistance range of 0.1 ohms to 10 Mohms. Its ultra small size (0402 inch size) offers high packing density, making it ideal for miniaturized electronic circuits. It is also designed for improved heat dissipation, allowing it to operate at higher temperatures than regular SMD resistors. It is UV resistant, and protected against ESD effects.
