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.
