MALVERN, Pa.--(BUSINESS WIRE)--
Vishay Precision Group, Inc. (NYSE: VPG) today announced that its Vishay
Foil Resistors brand (VFR) has released a new series of high-precision
foil surface-mount current sensing flip chip resistors with low TCR down
to ±10 ppm/°C from -55°C to +125°C, +25°C ref.; resistance down to 0.001
Ω; and tight tolerances to ±0.5%. Within this series, the RBH model is
offered with a four-terminal Kelvin design. While typical current
sensing resistors offer load-life stability of 0.5% through a 1,000-hour
workload, the RB Series provides stability of ±0.05% at 70°C for 2,000
hours at rated power and screening options in accordance to MIL-PRF
55342 and MIL-PRF 49465 for enhanced reliability and performance in a
range of applications, including precision current measurement.
The RB Series includes the RBD, RBF, and RBH resistors, which offer
power ratings of 0.5 W, 1 W, and 1.5 W, respectively, in compact case
sizes. The devices feature short time overload of ±0.03% (300 ppm); a
voltage coefficient of <0.1 ppm/V; a non-inductive (<0.08 μH),
non-capacitive design; and a resistance range from 0.001 Ω to 1 Ω.
The RB Series, built on VFR’s Bulk Metal® Foil technology and
developed by the company’s R&D team in Japan, outperforms all other
resistor technologies available today for applications that require high
precision and high stability. It provides a low and predictable TCR, as
well as excellent load-life stability, and allows for the production of
customer-oriented products designed to satisfy challenging and specific
technical requirements. The devices’ flip chip configuration saves 35%
on PCB space when compared to a surface-mount chip with wraparound
terminations.
“Designers often unnecessarily pay for tighter tolerances than required
simply to accommodate the resistance stability shifts they know to be
imminent in an application due to the large application-related changes
in the components they selected,” said Yuval Hernik, senior director of
application engineering for VFR. “Selection of a high-stability
component such as the RBD,
RBF, or RBH in these applications eliminates the need for shift
allowance due to ‘planned instability’ and allows the use of looser
initial tolerances than would be necessary with resistors based on other
technologies. In addition, overall system costs are often reduced
further by eliminating the necessity of additional compensating
circuitry or temperature-controlling systems.”
“We’re proud of the unique history of VFR resistors in Japan, the
quality resistive devices created in our domestic factory, and the
people who work there to provide our customers with the best technical
support and short lead times for our standard and customized precision
resistors,” continued Hernik.
Samples and production quantities of the RB Series are available now,
with lead times of five working days for samples and six weeks for
larger orders.
