Highly reliable metal alloy resistors manufactured by TT Electronics have been certified by AEC-Q200 (Active Electronic Component Certification Specification)

Ideal Current Sensing Device for Industrial, Medical and Automotive Applications

The LRMAP5930 high-power shunt resistor from TT Electronics is a product specifically designed for power supply and motor drive in the industrial, automotive and medical industries. It is an ideal product that can be used in many specific fields such as regulating current and detecting stoppages. Turn the motor, and (especially) measure power consumption. The development of electric drives and actuators in the industrial and automotive industries has witnessed common progress in both development and monitoring, and reduction in energy consumption. For the automotive market, the LRMAP5930 has been certified by the AEC-Q200 (Active Electronic Component Certification Specification). Other uses of the product include power supply, battery monitoring, and process control.

The LRMAP5930 has a resistance range of 200mW to 2mW, and the highest surge energy performance of this resistor is 33J. This product is very rugged and consists of a continuous electron beam welded precision resistor chip and uses a variety of alloys depending on the resistance value required.

The surface-mounted shunt resistors have low thermal resistance, which minimizes temperature rise and enhances the reliability of the assembly. At the same time, the product is highly tolerant to surges, enabling reliable product performance in surge currents and transient short-circuit conditions. The product's long-term numerical stability, low TCR (temperature coefficient of resistance), and low EMF (electromagnetic field) mean that the product consumes only a small part of the designer's error estimates and the designer can enjoy more design freedom in the circuit design process .

For designers who need to ensure stable and accurate sensing of AC and DC currents up to 200A in SMT (Surface Mount Technology) assemblies, the LRMAP5930 high-power shunt resistors from TT Electronics can reach or exceed Rated power of components produced by major competitors (under most ohmic values). It is very important that norm-setters and designers should compare the rated power and take into consideration the installation conditions during this process. TT Electronics provides a clear definition in the resistor data sheet that shows the dual rating and thermal substrate mounting type based on the standard FR4 PCB.
