Bulk Metal® Foil Technology High Precision  
4-Terminal Power Current Sensing Resistors with  
TCR as low as ꢀ ꢁꢁmꢂ/C and Tolerance 0ꢃꢀ ꢄ  
FEATURES  
Temperature Coefficient of Resistance (TCR):  
down to 1 ppm/°C Max. (see table 2)  
Pb-free  
Available  
Tolerance: to 0.1 % (see table 1)  
Power Rating (heat-sinked): 10 W  
RoHS*  
COMPLIANT  
Load Life Stability: 0.05 % at 25 °C, 2000 hours at Rated  
Power  
Resistance Range: 0.005 Ω to 500 Ω  
Electrostatic Discharge (ESD) above 25 000 V  
Non Inductive, Non Capacitive Design  
Rise Time: 1.0 ns without ringing  
Current Noise: < - 40 dB  
Any value at any tolerance available within resistance range  
The 300 Series offers precision Bulk Metal® Foil technology  
resistors as low as 5 mΩ with a temperature coefficient  
down to 1 ppm/°C and unmatched long term stability. The  
4 terminal current sensing resistors, when mounted on a  
heat sink, can sustain 10 watts continuously without an  
appreciable change in resistance (0.15 % maximum). The  
typical 50 % power derating specification associated with  
other technologies is not necessary. A choice of lead  
configurations is available.  
Thermal EMF: 0.05 µV/°C typical  
Voltage Coefficient: < 0.1 ppm/V  
Non Inductive: 0.08 µH  
Non Hot Spot Design  
Terminal Finishes available: Lead (Pb)-free  
Tin/Lead Alloy  
Any value available within resistance range (e.g. 1K2345)  
Prototype samples available from 48 hours. For more  
information, please contact foil@vishay.com  
Our Application Engineering Department is available to  
advise and make recommendations. For non-standard  
technical requirements and special applications, please
