Recommended Circuit Board Layout

(current and sense connections):

Note 2: Thermal Resistance - In High Power Applications where the circuit board

material provides high heat sinking beneﬁts (such as IMS, Alumina, or other) the thermal

resistance of the chip resistor is useful to establish the maximum power capability of the

chip resistor in the application. The ﬁlm temperature is measured at the center of the

resistor element and the solder pad temperature is measured at the center of the

termination pad (point X in the recommended circuit layouts shown below). Maximum

temperature of the chip resistor (at the center of chip) should not exceed 150°C through

the temperature range of the application
