Power shunts deliver long-term stability
Now available in Europe through TTI are PSJ2/PSL2 (2 terminals) and PSG4/PSF4 (4 terminals) series power shunts from KOA which have been newly added to the PS series. Constructed using a solid metal alloy resistance element with copper terminals the devices provide superior corrosion and heat resistance, along with excellent pulse resistance and long-term stability.
The products are ideal for accurate high current sensing up to 244A (PSJ2; 0.2mΩ; 12W) in automotive, industrial and pulse applications.
The rated power dissipation of the devices is 10W for 0.5mΩ versions and 8W for 1mΩ types at a maximum +75°C terminal part temperature.
The resistors feature a resistance tolerance of ±1% and a T.C.R. of ±50/±75 pm/K. The operating temperature range is very wide (-65°C up to +175°C).
All products are fully RoHS compliant as well as AEC-Q200 qualified.
