CSM Series
Bulk Metal® Technology High Precision, Current Sensing,
BulkMetal®TechnologyHighPrecision,CurrentSensing,PowerSurfaceMount,MetalStripResistor
Power Surface Mount, Metal Strip Resistor
with Resistance Value from 1 mΩ, Rated Power up to 3 W
and TCR to 0 1ꢀ ppmꢁ/C Maꢂimum
FEATURES
• Temperature coefficient of resistance:
15 ppm/°C max. (–55°C to +125°C, +25°C ref.);
10 ppm/°C max. (–55°C to +125°C, +25°C ref.)
is available on request (see table 1)
• Power rating: 1 W to 3 W
• Resistance tolerance: 0.1%
• Resistance range: 1 mΩ to 200 mΩ
• Bulk Metal® Foil resistors are not restricted to standard
values, specific “as required” values can be supplied at
no extra cost or delivery (e.g., 2.3456 mΩ vs. 2 mΩ)
• Load life stability to 0.2% (70°C, 2000 h
at rated power)
• Short time overload: 0.1% typical
• Thermal EMF: 3 µV/°C (DC offset error, significant
for low values)
INTRODUCTION
