Surface-mount power metal strip resistor
VISHAY Intertechnology, represented in Australia by Soanar , has released a new 1/10W surface-mount power metal strip resistor that is the industry’s smallest device to combine a low 15Ω to 100Ω resistance value range, a tight tolerance of 1% and low RTC values down to 75ppm/C°.
Available in the compact 0603 package size, the new WSL0603 resistor serves in all types of current-sensing, voltage division and pulse applications.
It is intended for power management in mobile phones and pagers, electronic automotive systems including engine controls, audio electronics and climate controls and disc drive motor control and dc to dc converters in computers.
With its very small footprint, low resistance values and low RTC, the new resistor facilitates current-sensing accuracy, which in turn allows designers to use lower-cost ICs.
The surface-mount WSL0603 resistor may be used in lieu of larger components or multiple high-value resistors running in parallel to provide space savings on the printed circuit board, thereby enabling design of smaller and lighter end products.
In addition to a power rating of 0.1W, the Vishay Dale WSL0603 offers low inductance values from 0.5nH to 5nH, excellent frequency response and low thermal EMF. It is rated for an operating temperature range of 65°C to +170°C.
The new device, which features an all-welded construction with solderable terminations, is easily placed with automated assembly equipment. It is available with a solid metal nickel-chrome alloy resistive element.
The WSL0603 is available in tape-and-reel packaging.
Samples and production quantities of the new resistor are now available, with a lead time of four to five weeks for larger orders.
