SMHP35 Series Power Resistor
SMHP35 Series * * * * * * 270C reflow compatible TO-263 housing Low inductance and capacitance for high frequency circuits 35W power rating High stability film resistance elements RoHS compliant
IRC's SMHP series resistors satisfy demanding applications for accurate and stable power resistors housed in the convenient TO-263 case. The resistance element is isolated from the mounting tab by an alumina ceramic layer, providing very low thermal resistance and ensuring high insulation resistance between terminals and metal back plate. The non-inductive design makes these products especially useful in high frequency and high speed pulse applications.

Application Notes:
1. Resistance measurement shall be made at the terminal foot. 2. Thermal design should satisfy the following equation: Tab Temperature (TT) + [Thermal Resistance (RqJT) x Power applied (Watts)] 155C over the full operating temperature of the application. 3. Resistor film temperature is not to exceed 155C 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.
Resistance Code
4-digit resistance code. Ex: 0R05 = 0.05, 10R0 = 10, 1K00 = 1K
