Building on TT's expertise in current sense resistors engineered to meet demanding accuracy targets, this new innovation offers values down to 200µΩ at 1% tolerance with TCRs down to 50ppm/°C.
 
The low TCR and low inductance of this design allow accurate current sensing without compensation circuitry. With a short-term overload rating up to 15W for 5s and high energy capacity, this robust solution is designed to withstand high inrush or switching surges.
