Vishay Techno  
Thick Film Technology Power Resistors  
20 Watt and 30 Watt TO220 Package  
FEATURES  
• Available with 20 or 30 Watt power rating  
• Convenient TO220 package  
• 20 Watt: Resistance range 1 Ω to 1 MΩ  
• 30 Watt: Resistance range 0.5 Ω to 100 KΩ  
• Tolerance 1 ꢀ standard  
• TCR to 50 ppm/°C  
• Non-Inductive Design  
• Isolated electrical element  
The well known TO-220 package combined with the proven  
thick film technology provides you, the design engineer, with  
a high reliable and cost effective solution for applications  
requiring current limiting/current sensing.  
ELECTRICAL SPECIFICATIONS  
Resistance Range: 20 Watt: 0.5 Ω to 100 kΩ  
30 Watt: 0.5 Ω to 100 KΩ  
STD Resistance Tolerance: 1 ꢀ, 2 ꢀ, 5 ꢀ and 10 ꢀ  
(Tighter available)  
The chips unique attachment to the solder coated copper  
base provides a repeatable low thermal resistance path for  
the energy to exit the resistor and be dissipated into the  
heatsink.  
Power Dissipation:  
TRP20:  
20 Watts at 25 °C with heatsink  
2 ¼ Watts at 25 °C without heatsink  
TPR30:  
The popular TO-220 package can be handled easily by the  
manufacturing group.  
30 Watts at 25 °C with heatsink  
2 ½ Watts at 25 °C without heatsink  
Temperature Coefficient: 100 ppm/°C Std  
( 50 ppm/°C available)  
Vishay has additional solutions when higher Technical  
Performance is required such as the VPR220 and VPR221.
