Schematic Layout
Recommended Solder Pad Layout
The LRK low range flip chip resistor series offers very low
resistance four terminal (Kelvin) layout for applications
requiring low cost and precision current measurement. The LRK
flip chip utilises patented, non-noble copper based inks which
demonstrate high performance, precision and reliability.
