VHP-3, VHP-4, VPR247 Vishay Foil Resistors Bulk Metal® Foil Technology Hermetically Sealed Power and Current Sensing Resistor with TCR of 2 ppm/°C and Power up to 10 Watts FEATURES • Temperature coefficient of resistance TCR: ± 2 ppm/°C typical (- 55 °C to + 125 °C, + 25 °C ref.) (see tables 1 and 2) Pb-free Available RoHS* • Tolerance: to ± 0.01 % (see tables 1 and 2) COMPLIANT • Power rating (heat-sinked): 10 W • Load life stability: ± 0.01 % at 25 °C, 2000 h at rated power • Resistance range: 0.05 Ω to 80 kΩ Any value available within resistance range • Electrostatic discharge (ESD) above 25 000 V Vishay Bulk Metal® Foil power resistors offer the best approach to low value power and current sensing when a combination of accuracy, tight TCR, low thermal EMF, low voltage coefficient, Kelvin connection, and long term stability (under power) are required. • Non inductive, non capacitive design Vishay Models VHP-3 and VHP-4 offer all welded construction and screw mounting directly to a metal heat sink for maximum heat transfer. Hermetic sealing and nitrogen back fill provide the maximum protection against environmental stresses, thereby ensuring long term stability. A special feature of this construction is Kovar eyelet’s and OFHC solder plated copper leads providing the lowest thermal EMFs in the industry. • Voltage coefficient: < 0.1 ppm/V Vishay Model VPR247 has many of the advantages of the VHP-4 but with significantly reduced size and weight. It also has gold plated copper leads. • Any value available within resistance range (e.g. 1K234) Our Application Engineering department is available to advise and to make recommendations. For non-standard technical requirements and special applications, please contact us. • For better performances, please contact Application Engineering • Rise time: 1.0 ns without ringing • Current noise: < - 40 dB • Thermal EMF: 0.05 µV/°C typical • Non inductive: 0.08 µH • Non hot spot design • Terminal finishes available: VHP-3 and VHP-4: VPR247: lead (Pb)-free tin/lead alloy gold plated • Prototype samples available from 48 h.

In these applications the contact resistance, lead resistance, and their TCR effect may be greater than that of the element itself and could cause significant errors if the standard 2-terminal connection is used. Figure 2 shows a high impedance measurement system where r5 approaches infinity and Im approaches zero resulting in negligible IR drop through r3 and r4 which negates their lead resistance and TCR effect. With the voltage sense leads E1 and E2 inside of r1 and r2 the resistance and TCR effect of the current leads, I1 and I2 are negated and only the resistance and TCR of the element R are sensed. This method of measurement is essential for precise current sensing. VHP-4 (4 terminal) Mounting Hole 0.770 (19.56) Max.
