The AC0603JR-0727KL is a thick film resistor with a 1/10 watt (0.1W) power rating, a resistance value of 27K ohms, and a tolerance of 5%. This resistor is manufactured by Yageo and is also AEC-Q200 certified, which means that it has passed rigorous testing for use in automotive applications, including vibration, thermal shock, mechanical shock, salt spray, humidity, and temperature measurements. The size of this particular resistor is what is known as an 0603 package, which is a miniature version of a 0805 package and is very small (approximately 1.6 mm × 0.8 mm). This resistor can be used in a wide variety of applications, including high-frequency circuits, general-purpose operations, and power supplies.
