The PSR100KTQFJ2L00 is a Current Sense Resistor manufactured by ROHM, specifically an SMD 2512 2mohm 1% Shunt Resistor. This part is used to measure and monitor current flow in a circuit, helping to prevent damage caused by overloads or surges by quickly detecting these scenarios. The SMD 2512 package provides a very small and fine-pitch footprint, allowing for higher sensitivity in current measurements. The PSR100KTQFJ2L00 features a tolerance of 1%, making it suitable for applications requiring high precision current measurements while the 2mohm value provides a high load-to-current ratio for increased efficiency. The PSR100KTQFJ2L00 is RoHS-compliant and comes with a voltage of up to 400V, a resistance value of 2mohm, and a current rating of 1A.
