H Series  
Vishay Foil Resistors  
Hermetically Sealed High Precision Bulk Metal® Foil Technology  
Resistors with TCR of ꢀ ꢁꢁmꢂ/C, Tolerance of ꢃ0ꢃꢃꢄ ꢅ and  
Load Life Stability of ꢃ0ꢃꢃꢆ ꢅ  
FEATURES  
Temperature coefficient of resistance (TCR):  
Pb-free  
2 ppm/°C typical  
(- 55 °C to + 125 °C, + 25 °C ref.)  
Available  
RoHS*  
Power rating: 0.3 to 2.5 W at + 25 °C  
COMPLIANT  
(depending on model - see table 2)  
Tolerance: to 0.001 %  
Any value at any tolerance available within resistance range  
Load life stability: 0.005 % (70 °C for 2000 h at half rated  
power)  
Shelf life stability: 2 ppm for at least 10 years  
INTRODUCTION  
Resistance range: 5 Ω to 1.84 MΩ (higher or lower values  
of resistance available)  
The H series resistors are oil-filled, hermetically sealed ultra  
precision resistors.  
Electrostatic discharge (ESD) above 25 000 V  
Rise time: 1.0 ns without ringing  
Current noise: < - 40 dB  
The hermetic sealing eliminates the ingress of moisture and  
oxygen, while the oil acts as a thermal conductor, thus  
eliminating long term degradation elements of unsealed  
resistors, while at the same time allowing the device to  
accept short periods of overload without degradation.  
Thermal EMF: 0.05 µV/°C typical  
Voltage coefficient: < 0.1 ppm/V  
Non inductive: < 0.08 µH  
Vishay’s Bulk Metal® Foil outperforms all other resistor  
technologies available today for applications that require  
precision and stability. When combined with the hermetic  
sealing and oil filling, the H series resistors become one of  
the most ꢁrecise and stable resistors available.  
Non inductive, non capacitive design  
Non hot spot design  
Terminal finishes available: lead (Pb)-free  
tin/lead alloy  
Impervious to harmful environments - oil-filled  
With accuracies of 0.001 %, a resistance range from 5 Ω  
to 1.84 MΩ, and long term shelf life of less than 2 ppm,  
these devices are virtually secondary standards that can be  
carried in sets for daily or periodic calibration of factory  
measurement equipment.  
Any value available within resistance range (e.g. 1K234)  
Prototype samples available from 48 h. For more  
information, please contact foil@vishay.com  
For better performances, please see H series (Z)  
Note  
Load life stability can be considerably improved through in-house  
oriented tests
