IRC/TT Electronics LRMAP5930 Low Resistance Metal Alloy Power Resistors are high power, low-value SMT shunt resistors ideal for industrial, automotive, and medical markets.
With values down to 200μΩ and a corresponding power rating on FR4 of 10W, the maximum measurable current is over 200A, and therefore in most cases restricted only by the capacity of the PCB tracks. A power rating of up to 15W may be achieved for assemblies on thermal substrates like DBC ceramic or IMS, making this part ideal for power hybrid modules. Low thermal impedance minimizes the temperature rise and enhances the reliability of the assembly. High surge tolerance gives reliable product performance under inrush and momentary short circuit conditions. Good long-term stability of value, low TCR, and low thermal EMF all mean that a small part of the designer’s error budget is consumed, enabling more design freedom elsewhere in the circuit.
