Notes
• For the assembly, we recommend the lead (Pb)-free thermal profile as per J-STD-020C.
• Power dissipation is 3.2 W at an ambient temperature of 25 °C when mounted on a double sided copper board using FR4 HTG, 70 μm of
copper, 39 mm x 30 mm x 1.6 mm, with thermal vias.
• For other information about dissipation, see the Application Note 52027: “Thermal Management on SMD Thick Film Resistors (D2TO20,
D2TO35, DTO25)”.
