- Low resistance values allow systems designers to maximize available board space by using a single resistor instead of multiple higher-value resistors in parallel, or by replacing larger low-value resistors with a smaller 2816 footprint
- Current-sensing accuracy afforded by the tight 1% tolerance and low resistance and low RTC of the WSL2816 enables designers to use lower-cost ICs
- Proprietary production techniques result in an extremely low resistance value range of 10 milliohms to 100 milliohms
The
Key Applications:
- Current sensing, voltage division, and pulse applications such as motor controls and dc-to-dc converters in automotive, consumer, and industrial systems

Vishay’s New 2-W Surface-Mount Power Metal Strip Resistor Features
Low Resistance Value Range of 10-100 mΩ and 1% Tolerance
Vishay Intertechnology, Inc. (NYSE: VSH) announces the release of the WSL2816, a new 2-W, surface-mount Power Metal Strip® resistor with a low resistance value range of 10 milliohms to 100 milliohms and tight 1% tolerance..
- Proprietary production techniques featuring all-welded construction with a solid metal nickel-chrome alloy resistive element and solderable terminations result in extremely low resistance values
- Available board space can be maximized by using a single resistor instead of multiple higher-value resistors in parallel, or by replacing larger low-value resistors with a smaller 2816 footprint
-
Lower-cost ICs can be used because of the current-sensing accuracy afforded by the tight tolerance and low resistance and low RTC
Key
Device Specifications:
- Power rating of 2 W
- Very low inductance of 0.5 nH to 5 nH
- Resistance
values ranging from 10 mΩ to 100 mΩ
- Tight tolerance of ±1.0%
- Dimensions of 0.280 in. by 0.165 in. by 0.025 in. [7.1 mm by 4.2 mm by 0.635 mm]
-
Operating temperature range of -65 °C to +170 °C
The Perspective: The current-sensing accuracy and low resistance values of Vishay’s new WSL2816 Power Metal Strip resistor enables designers to use lower-cost ICs and maximize board space by using a single small resistor instead of multiple or larger low-value components
Availability: Samples and production quantities of the new WSL2816 resistor are available now, with lead times of four to six weeks for larger orders.
