The sensing resistor value is generally lower

than 1ohm, but a wire wounded type must be

avoided. In Fig.3 the 0.33 ohm sensing resistor

is shown as three parallel 1ohm metal film resis-

tors. Care must be taken in the PC Board design

particularly abou t ground loops and ground cop-

per area. The typical Thermal Resistance junction

to ambient versus PC Board copper area (Fig.7)

is shown in Fig 8. For Transient Thermal Resis-

tance see Fig. 9.
