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)
? Tolerance: to ± 0.01 % (see tables 1 and 2)
P b -free
A v aila b le
RoHS*
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 k Ω
Any value available within resistance range
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.
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
? Electrostatic discharge (ESD) above 25 000 V
? Non inductive, non capacitive design
? Rise time: 1.0 ns without ringing
? Current noise: < - 40 dB
? Thermal EMF: 0.05 μV/°C typical
? Voltage coefficient: < 0.1 ppm/V
? Non inductive: 0.08 μH
? Non hot spot design
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.
? Terminal finishes available:
VHP-3 and VHP-4:
VPR247:
lead (Pb)-free
tin/lead alloy
gold plated
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.
