Open Air Resistor, Metal Element Current Sense, Low Ohm
Current sense open air resistors are expected to gain wide acceptance in the worldwide market as a result of increased thermal management capabilities.
The FLQ series is designed for applications requiring the transfer of heat away from circuits and solder joints. Available in 0.5W, 1W, and 1.5W rating, the resistor is being specified for current sensing, feedback, current detective, supper low inductance, as well as surge and pulse applications.
The hot spot on the open-air resistor is approximately 0.2 degrees higher than on a typical metal strip chip resistor. This results in an increased thermal path for the FLQ, reducing heat transfer into the solder joints and circuits.
The flameproof FLQ low resistance value resistors are constructed of a wire resistive element with welded copper leads to prevent solder wicking, which can change the device's resistance value in the circuit by as much as 30%. Because of this, the device is ideal for thermally harsh environments, including automotive and aerospace applications, as well as enclosed, poorly ventilated circuits in applications such as laptop computers.
