Vishay’s Chip Resistors Deliver Precision and Stability
Vishay Intertechnology Inc. has released the new VSM series of Bulk Metal® foil ultra-high-precision wrap-around, surface-mount chip resistors, the first devices to combine a low and predictable TCR value of 2 ppm/°C (-55 °C to +125 °C), load life stability of 0.01 %, and tight tolerance of 0.01 %.
Available in five small package sizes (0805, 1206, 1506, 2010, and 2512), the new chip resistors feature an exceptional power-to-size ratio, delivering up to 400 mW in one small surface-mount resistor. The five chip resistors announced today are rated for a resistance range of 10Ω to 150 kΩ.
With low inductance of 0.08µH and low current noise of -40 dB, these VSM devices provide virtually noise-free operation in applications requiring high precision and high stability: automatic test equipment (ATE); precision instrumentation; laboratory, industrial, medical, and audio systems; electron beam scanners, recorders, and microscopes; military, space, airborne, and aerospace systems; down-hole instrumentation; and communications systems.
Low thermal EMF of 0.05 µv/°C and shelf-life stability of 0.005% contribute to the devices' improved performance. A full wrap-around termination ensures safe handling during the manufacturing process and provides stability during multiple thermal cycling. As a result, the load-life stability of foil resistors is unparalleled, and the long-term serviceability of the end product is assured.
Available in waffle-pack and tape-and-reel packaging, samples and production quantities of the new VSM series resistors are available now. Both lead (Pb)-free and tin/lead alloy terminal finishes are available. Pricing for U.S. delivery starts at $3.00 and depends on quantity, value, and tolerance.
