Surface Mounted Power Resistor Thick Film Technology

ADDITIONAL RESOURCES

FEATURES

• AEC-Q200 qualified

• 25 W at 25 °C case temperature

• Surface mounted resistor - TO-252 (DPAK)

style package

• Wide resistance range: 0.016  to 700 k

• Non inductive

• Resistor isolated from metal tab

• Solder reflow secure at 270 °C / 10 s, MSL = 1

• Material categorization: for definitions of compliance

please see www.vishay.com/doc?99912

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)”
