Vishay Foil Resistors  
Ultra High Precision Bulk Metal® Z-Foil Technology  
Power Current Sensing Resistors with TCR of ± 0.05 ppm/°C  
and Power Rating up to 7 W  
FEATURES  
NEW  
• Temperature coefficient of resistance (TCR):  
± 0.05 ppm/°C (0 °C to 60 °C)  
± 0.2 ppm/°C (- 55 °C to + 125 °C, + 25 °C ref.)  
• Tolerance: ± 0.01 %  
• Resistance range: 5 Ω to 100 KΩ  
• Vishay Foil Resistors are not restricted to standard values;  
specific “as required” values can be supplied at no extra  
cost or delivery (e.g. 1K2345 vs. 1K)  
INTRODUCTION  
• Load life stability: ± 0.01 % (100 ppm) at 70 °C, 2000 h at  
rated power  
These Bulk Metal® Z-Foil power current sensing resistors are  
direct replacements for certain wirewound devices but  
without the inductive characteristics of wirewounds. The  
anodized aluminum housing is drilled and countersunk to  
accept flat head screws for thermal mounting. Because the  
device is internally Kelvin connected, there is no restriction  
on the lead lengths as would be the case if this were a two  
terminal device. Frequently used in YIG oscillator circuits  
these devices contribute to superior frequency stability.  
• Electrostatic discharge (ESD) up to 25 000 V  
• Non-inductive, non-capacitive design  
• Rise time: 1 ns effectively no ringing  
• Current noise: 0.010 µVRMS/V of applied voltage (< - 40 dB)  
• Thermal stabilization time < 1 s (nominal value achieved  
within 10 ppm of steady state value)  
• Thermal EMF: 0.05 µV/°C typical  
• Voltage coefficient: < 0.1 ppm/V  
• Non-inductive: < 0.08 µH  
• Pattern design minimizing hot spots  
• Terminal finish available: lead (Pb)-free or tin/lead alloy*  
• Prototype quantities available in just 5 working days  
or sooner. For more information, please contact
