Resistors
Vishay Precision Group, Inc.
announced that its Vishay Foil
Resistors (VFR) brand has enhanced
its VSMP series of Bulk Metal®
Z-Foil ultra-high-precision wraparound
chip resistors with an
extended resistance range down to
5 Ω for sizes 0805 and larger. The
devices feature ultra-low TCR of
±0.05 ppm/°C typical (0°C to +60°C)
and ±0.2 ppm/°C typical (-55°C to
+125°C, +25°C ref.), and load-life
stability of ±0.005% at 70°C for
2,000 hours at rated power and
±0.01% at 70°C for 10,000 hours.
Available in seven chip sizes from
0603 to 2512, the VSMP series
offers high power ratings up to 750
mW at +70°C and an excellent
power coefficient of ±5 ppm at rated
power.
