Vishay Foil Resistors
Bulk Metal® Technology High Precision, Current Sensing, Power Surface
Mount, Metal Strip Resistor with Improved Stability 0.05 %, Resistance
Value from 10 m
Ω
, Rated Power to 1 W and TCR to 0 ± 15 ppm/°C
FEATURES
• Temperature coefficient of resistance (TCR):
(- 55 °C to + 125 °C, + 25 °C ref.)
± 15 ppm/°C maximum
± 10 ppm/°C maximum on special request
• Load life stability to ± 0.05 % (70 °C, 2000 h
at rated power)
• Power rating: 1 W
• Resistance tolerance: ± 0.1 %
• Resistance range: 10 mΩ to 100 mΩ
• Vishay Foil resistors are not restricted to standard values,
we can supply specific “as required” values at no extra cost
The CSM’s series of low value current sense resistors
provides power and precision in a four terminal, surface
mount configuration. Its all welded construction is made
up of a Bulk Metal® resistive element with plated copper
terminations.
or delivery (e.g. 10.2345 mΩ vs. 10 mΩ)
