TT Electronics debuts EBW8518 busbar-mounted shunt resistor  [ UK ]

TT Electronics announced E-Beam Welded Shunt­ resistors for industrial and automotive applications. The robust electron beam welded technology and low thermal EMF of this resistor make it advantageous for HEV battery management, energy metering and welding power supplies. EBW8518 is an electron beam welded resistance element, sandwiched between large copper terminals with optional tin plating. Precision applications can make use of its 1% tolerance, 100ppm/°C TCR, 1µV/°C thermal EMF and separate ground pins to reduce errors. The low measurement error of this resistor frees up the designer’s error budget and its low ohmic values reduces power loss. The EBW8518 provides the fullest selection of values in TT Electronics’ chosen range 50 to 250µ ohm. (From a press release on May 16, 2019)
