Application Notes
1. Resistance measurement shall be made at the terminal
foot.
2. Thermal design should satisfy the following equation: Tab
Temperature (T_T) + [Thermal Resistance (R_QJT) x Power
applied (Watts)] ≤ 155°C over the full operating temperature
of the application.
3. Resistor film temperature is not to exceed 155°C during
operation.
4. This product is RoHS compliant by exemption according to
RoHS directive 2002/95/EC exemptions 5 & 7, as they apply
to lead in glass and internal solder connections.
