Vishay WSL Power Metal Strip chip resistors

Vishay Electronic : 09 May, 2006  (New Product)
With very low TCR values of just 15 ppm/
Vishay Intertechnology, Inc. has announced three additions to the WSL series of surface-mount Power Metal Strip resistors.

With very low TCR values of just 15 ppm/C and high power ratings of 0.25 W, 0.5 W, and 1.0 W, respectively, in compact 1506, 2010, and 2512 case sizes, the new, patent-pending, extended-range flip chip WSL resistors from Vishay maintain the superior electrical characteristics of the Power Metal Strip construction while occupying a smaller mounting area on the printed circuit board. The new devices also provide good overload capability using the PC board as a cooling device and long-term stability through a broad range of environmental conditions, thereby enabling design of smaller, lighter, and longer-lasting end products.

The WSL1506E, WSL2010E, and WSL2512E feature good pulse-handling capability and a very broad resistance range of 0.5 Ω to 10,000 Ω, with standard tolerances of 1.0% and 0.5%. All three resistors also provide low-noise operation of <0.01 μ V(rms)/V, a voltage coefficient of <0.00001%/V (<0.1 ppm/V), and very low inductance of <0.08 μ H. They are specified for a category temperature range of -55 to +150.
