FEATURES
• Temperature coefficient: ±20 ppm/°C max.
(–55°C to +125°C, +25°C ref.) (see Table 1)
• Surface mount configuration
• Four terminal (Kelvin) design: allows for precision
accurate measurements
• Power rating: 1 W to 3 W
• Resistance tolerance: ±0.5%
• Resistance range: 2 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., 2.345 mΩ vs. 2 mΩ)
• Short time overload: 0.2% typical
• Thermal EMF: 3 μV/°C
• Maximum current: up to 38 A
• Terminal finish: tin/lead alloy
• For prototype units, append a “U” to the model number
(example: 303144U). These units have all of the table
2A (page 3) 100% tests performed, with no destructive
qualification testing required (table 3A, page 3).

INTRODUCTION
303144 and 303145 are low value current sense resistors,
providing 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.
The four terminal devices separate the current leads from
the voltage sensing leads. This configuration eliminates
the effect of the lead wire resistance from points A to B
and C to D.
Vishay Foil Resistors’ application engineering department
is available to advise and make recommendations.
