Current sense resistors are offered in 44-A, Zero Ohm and 1-W, 2010 versions
KOA Speer Electronics (Bradford, PA) introduced two current sensing resistors, the zero Ω SLZ and the 1W/2012 SLW07. The high current SLZ1 jumper chip offers a rated current of 44 A in a 2512 size. The SLW07 has an enhanced high power rating of 1 W in a smaller package size of 2010. KOA Speer's SLZ1 and SLW07 bBoth feature a wide temperature range of -55°C to +180°C. The SLZ1 has a max resistance of 0.5 mΩ, and the SLW07 is available in 0.5mΩ ~100 mΩ in both 1 percent and 5 percent tolerances. The chips' special electrode shape easily absorbs thermal expansion and shrinkage stress. The resistors are appropriate for applications such as:
- DC to DC conversion and AC adaptors.
- Notebook PCs.
- Battery packs, m.
- Motor controls.
- Automotive engineering and management systems.
- Low impedance connections.
