THE PRODUCTS DESCRIBED HEREIN AND THIS DOCUMENTARE SUBJECT TO SPECIFIC DISCLAIMERS, SET FORTH AT NOTEBy Bryan YarboroughPURPOSEC urrent sensing is used to perform two essential circuit functions. First, it is used to measure how much Current is flowing in a circuit, which may be used for power management in a DC/DC power supply to determine essential peripheral loads to conserve power.
Vishay Thick Film Resistor Products: The RCWE and RCWL are typically 0.0005" to 0.002" thick, which is nearly 100 times that of thin film. The increased thickness equates to a greater mass that is better able to carry the relatively high currents and dissipate the heat across the substrate, as well as better able to manage transients.
