Yageo RC1210JR-072R7L is a thick film resistor, manufactured in a surface-mount design (SMD), with a resistance value of 2.7 ohm, and a tolerance of +/- 5%. The resistor is a called a thick-film resistor because it is made using the thick-film technology. In this method, a thick layer of resistive material is deposited onto an insulating substrate, and then coated with an additional layer of protective material. The substrate used in Yageo RC1210JR-072R7L is an alumina ceramic, known to be one of the most reliable materials for resistors. The resistor's package dimensions are 0603 (1.6 mm x 0.8 mm), and it can operate at temperatures from -55°C to 155°C.
