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

terminations.

Vishay Foil Resistors’ application engineering department is

available to advise and make recommendations.

For non-standard technical requirements and special

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

or delivery (e.g. 10.2345 m

Ω vs. 10 mΩ)

• Short time overload: ± 0.1 % typical

• Thermal EMF: < 3 µV/°C

• Maximum current: up to 10 A

• Surface mount configuration

• Four terminal (Kelvin) design: allows for precision accurate

measurements

• Terminal finishes available: lead (Pb)-free, tin/lead alloy

• Screening in accordance with EEE-INST002 available

(Per

MIL-PRF-55342

and

MIL-PRF-49465;

see

datasheets of 303144 and 303145 )

• Prototype quantities available in just 5 working days or

sooner.
