HoLRS Series Ultra-Low Temperature Drift High Precision Metal Alloy Current Sense Resistor

1. Resistance value: Determine the required range of resistance values according to the requirements of the circuit.
2. Accuracy: Select the accuracy level based on the measurement error that the circuit can accept, usually including 0.1%, 0.5%, 1%, 3%,and 5%.
3. Temperature coefficient: The temperature coefficient of alloy resistors is usually in the range of a few parts per million, and can be selected according to different application requirements. The selection needs to be based on the temperature range of the circuit operation, usually including 10ppm, 20ppm, 25ppm, 50ppm, 75ppmm, 100ppm, etc. (Figure ①).
4. Power: Determine the required power range according to the requirements of the circuit.

       6.Material: Determine the required whole alloy resistor material according to the requirements of the circuit. For example, using nickel iron alloy under AC or high-frequency conditions may cause significant temperature rise. The use of nickel chromium alloy can effectively reduce such             phenomena.

The Milliohm Brand HoLRS series of whole alloy resistors (Fig. 2) are independently  designed by Shenzhen Milliohm Electronic Co.,Ltd, meeting the characteristics of  high precision, low temperature drift, high power and other parameters; they are welded with professional self-controlled
electron beam welding equipment. Based on the perfect combination of professional design capability, high-precision processing equipment, and strict process control system, the products can achieve the highest target accuracy of ±0.1%, TCR ≤ ±25~ 50ppm/°C within the range of -55℃~+170℃, and inductance <0.003μN. And the HoLRS series of pure alloy resistors are compliant with testing standards of ROHS and AEC-Q200 tests.

Widely used Applications: Current sensing, Voltage division,Battery management systems, Power modules, Frequency converters, Industrial, Motor controls, Automotive electronics, Communication systems
