MALVERN, Pa.--(BUSINESS WIRE)--
VPG
Foil Resistors, a Vishay Precision Group, Inc. (NYSE:VPG) product
group, announced today that its Vishay
Foil Resistors brand has introduced a new current sense resistor for
the medical, energy, military and aerospace markets. The high-precision,
surface-mount, four-terminal CSM3637F
current sense resistor is an industry first due to its size in
combination with an improved load-life stability of +/-0.02% at +70°C
for 2,000 hours with a low TCR of +/-5 ppm/°C max from -55°C to +125°C
and a high power rating up to 3 W.
The CSM3637F resistor is optimized for high-precision current sensing
applications in switching linear power supplies, power amplifiers, power
management systems, feedback circuits, measurement instrumentation and
automatic test equipment. The device features a resistance range from
50 mΩ to 200 mΩ with any conceivable ohmic value within this range — out
to six digits — available with no additional cost or lead time effect.
The resistor provides ESD immunity to 25 kV or more, power coefficient
of resistance (ΔR due to self-heating) of 5 ppm/W at rated power, and
tight tolerance of +/-0.1%.
The CSM3637F resistor’s unique combination of Bulk Metal® Z
Foil Technology and a four-terminal Kelvin connection results in a
significant reduction of the device’s sensitivity to applied power
changes such as power coefficient of resistance (PCR) and thermal
resistance, while its low TCR reduces errors due to temperature changes.
Short-time overload tests applying 10 W power for 5 seconds on the
device were passed with a maximum ∆R of 0.01%.
“The CSM3637F resistor is the ideal solution for applications up to 3 W
where the emphasis is on accuracy and repeatability under stressed
conditions and swift current changes, such as current power supplies,
deflection amplifiers, electron microscopes, electron beam systems and
force-balanced scales,” said Jacky Acoca, sales and marketing director,
VPG Foil Resistors. “Such products require a precise voltage
proportional to the current, and the CSM3637F resistor delivers with its
unique design, low TCR, and excellent load-life stability.”
“The stability of Bulk Metal® Z Foil resistors, as well as
the other basic advantages apparent in Bulk Metal® Z Foil
specifications, will not only provide unequalled performance in the
circuit, but will eliminate all the costs associated with extra
compensation circuitry,” added Hero Faierstain, application engineering
senior manager, Vishay Foil Resistors. “With the CSM3637F, only a
minimal shift in resistance value will occur during its entire lifetime.
Most of this shift takes place during the first few hundred hours of
operation, and virtually no change is noted thereafter.”
Samples and production quantities of the new CSM3637F resistors are
available now with lead times of five to eight weeks, either
RoHS-compliant (lead (Pb)-free) or with tin/lead alloy terminations. The
CSM3637F resistors will be among the products on display during
electronica 2016 at the VPG Foil Resistors booth B6/116 at the Messe
München, November 8-11.
