Vishay Intertechnology Power Metal Strip® Resistor Saves Space With 7 W Rating and Resistance to 1 mΩ in 2818 Case Size

Business Wire
Vishay Intertechnology, Inc. (NYSE: VSH) today announced a new
surface-mount Power Metal Strip® resistor designed to save space in
automotive, industrial, computer, and consumer applications. The
Vishay Dale WSHM2818 combines a high 7 W power rating with
extremely low resistance values down to 1 mΩ in the compact 2818
case size.
The advanced construction of the WSHM2818 resistor incorporates
improved thermal management and a solid metal nickel-chrome or
manganese-copper alloy resistive element with low TCR (< 20
ppm/°C). This results in a high-power resistor in the 2818 package
size that maintains the superior electrical characteristics and
performance of the Power Metal Strip construction, such as
excellent 1,000-hour load life stability and very good resistance
to short time overload of < ± 1 %. The device’s high
power-to-footprint-size ratio allows designers to save board space
and create smaller end products by replacing larger resistors with
similar power capability and multiple devices with lower power
ratings.
The AEC-Q200-qualified resistor is ideal for all types of
precision current sensing, voltage division, and high power pulse
load applications, including switching regulators, current
detectors, power supplies and power amplifiers in automotive
electronic controls such as engine, injector, brushless DC motors,
anti-lock brakes, climate, and battery management controls.
The WSHM2818 also fits into industrial controls, including
down-hole test/measurement equipment for oil/gas well drilling;
inverter controls for HVAC systems; motor drives and DC/DC
converters for servers, VRMs for computers, and Li-ion battery
safety and management.
Like all Power Metal Strip resistors, the device released today
features an all-welded construction that contributes to its
superior electrical performance. A proprietary processing technique
produces extremely low resistance values ranging from 1 mΩ to 100
mΩ, with tight tolerance of ± 1.0 %. The WSHM2818 provides very low
inductance of < 5 nH, an excellent frequency response to 50 MHz,
low thermal EMF (< 3 μV/°C), and an operating temperature range
from -65 °C to +170 °C. The device is RoHS-compliant, halogen-free,
and Vishay GREEN.
Samples and production quantities of the new resistor are
available now, with a lead time of six to 10 weeks for larger
orders.
