New Product- 1206 2512 Current Sensing Resistors


The precision current sensing resistor is a fixed resistor with very low resistance error value, can flow a large amount of current, good weather resistance and mechanical strength, and high operating ambient temperature. At the same time, the resistance value drifts with temperature changes. Low; In addition, its electrical characteristics are stable, CSR is a resistor product with extremely high stability among fixed resistors
According to different materials and processes, there are four main resistance technologies: wirewound resistors, thick film resistors, thin film resistors, and metal foil resistors.

Main model would be 


Size Resistance
2512 3mOhm/4mOhm/5mOhm/6mOhm/7mOhm/10mOhm
1206 3mOhm/5mOhm/7mOhm/10mOhm


Explanation of current induced resistance



1. Resistance accuracy: resistance error range (D=0.5%, F=±1%, G=±2%, H=±3%, J=±5%)
2. Temperature Coefficient (TCR) : Resistance Drift Coefficient with Temperature

3. Rated power: At room temperature, the element can withstand the maximum power of the current flowing

4. Operating temperature range: the temperature range in which the element can operate

5. Power decay temperature point: the highest temperature at which the element produces power decay

6. Thermoelectromotive force : The error voltage coefficient of the element due to the Seebeck effect (thermoelectric effect)

7. Self-inductance: the error voltage coefficient of the component due to the magnetoelectric effect
