The WW20W series resistors from Walsin are thick film power low ohm chip resistors. These resistors are constructed in a high grade ceramic body (aluminium oxide). The WW20W series resistors are used in power supply, PDA, digital meter, computer, battery charger and DC to DC power converter.
Resistance range includes E24 decade values 0.010 ohm to 0.910 ohm
