The AC0805FR-07576KL 50%)is a Chip Resistor - Surface Mount 576kOhms ±1% 1/8W 0805 RoHS that is manufactured by Yageo. This resistor is an 805 size, meaning that the two legs on the resistor are 8 0.05 mm or .2 inch away from each other. This part is designed to be used on printed circuit boards in a wide range of electronic applications. The 576KOhm resistance value allows it to be used for various control functions, such as controlling off/on switches. This resistor also has a ±1% tolerance rating, which means that the resistor may measure up to 1% greater or 1% lesser than the specified value. It has a 1/8 watt power rating, so it can handle up to 1/8 watt of power, enough for small applications. This part is also RoHS, or Restriction of Hazardous Substances, compliant, meaning that it has been designed and manufactured with lower levels of hazardous materials than non-RoHS parts, making it a safer option for users.
