Vishay Sfernice
Surface Mounted Power Resistor
Thick Film Technology
FEATURES
• 20 W at 25 °C case temperature
• Surface mounted resistor - TO-263 (D
2 PAK) style
package
• Wide resistance range from 0.01 Ω to 550 kΩ
• Non Inductive
• RoHS compliant
• Resistor isolated from metal tab
• Solder reflow secure at 270 °C/10 s
DIMENSIONS in millimeters
Notes
• For the asssembly on board, we recommend the lead (Pb)-free thermal profile as per J-STD-020C
• Power dissipation is 2.8 W at an ambient temperature of 25 °C when mounted on a double sided copper board using FR4 standard, 70 µm of
copper, 39 x 30 x 1.6 mm.
