Vishay VSMP chip resistor range

Vishay has enhanced its VSMP series of bulk metal Z-foil ultrahigh-precision wraparound chip resistors with an extended range down to 5 Ω for sizes 0805 and larger.

The devices feature ultralow TCR of ±0.05 ppm/°C typical (0 to +60°C) and ±0.2 ppm/°C typical (-55 to +125°C, +25°C ref.), and load-life stability of ±0.005% at 70°C for 2000 h at rated power and ±0.01% at 70°C for 10,000 h.

Available in seven chip sizes from 0603 to 2512, the series offers high power ratings up to 750 mW at +70°C and a good power coefficient of ±5 ppm at rated power. The devices feature a wide resistance range from 5 Ω to 125 kΩ, with tight resistance tolerance to ±0.01%.

Any resistance value within this range is available at any tolerance with no additional cost or lead time effect. Matched resistor sets are available by request.

The low TCR makes them suitable for the demands of cryogenics. In addition, the devices are suitable for use in many alternative energy and smart grid applications, where analog circuitry operates under severe environmental, thermal and mechanical conditions.
