RT0402BRD07100RL is a 0402 package resistor manufactured by Yageo. It is a thin film resistor with a 1/16 watt power rating and 100 ohm resistance value. It has a tolerance of 0.1%, which means that the actual resistance value can be up to 0.1% greater or less than the 100 ohm nominal value. It has a temperature coefficient of 25ppm per degree Celsius, meaning that its resistance will change by 25 parts per million for each degree of temperature variation.
