60W 100W precision shunt high - power resistors.

1. Type of Resistor

• Planar (alloy - foil, non - inductive design) high - power resistors.

• The resistor chips are made of alloy - foil resistor materials, have low temperature coefficients and super - strong pulse endurance capabilities, and are suitable for current - sampling circuits and other aspects.

2. Technical Features

• The rated power is 60W/100W when the center temperature of the base plate is ≤70°C.

• SOT227 - type mold - press packaging, M4 - screw flange - base - plate packaging.

• The minimum resistance value is 1mΩ.

• Four - terminal connection.
