TT Electronics Introduces High-Power Shunt Resistor for Automotive Solutions
TT Electronics Unveils High-Power LRF4W SMT Shunt Resistors for Demanding Applications
BonChip Electronics, a premier distributor of TT Electronics products, is excited to announce the launch of the innovative LRF4W SMT shunt resistors. This AEC-Q200 qualified device caters to the growing need for accurate and reliable current sensing in applications like battery management, motor control, and power conversion.
Enhanced Power Density and Compact Design
The LRF4W leverages TT Electronics' expertise in current sense resistors to deliver exceptional performance:
- High Power Density: Utilizing low resistivity thick-film materials, the LRF4W offers class-leading power density for an alumina-based product. This translates to efficient heat dissipation and improved thermal performance.
- Compact Footprint: The 1225 inverse format footprint minimizes space requirements on PCBs, making it ideal for space-constrained designs.
- Broad Resistance Range: The LRF4W series offers resistance values ranging from 3mΩ to 100mΩ, catering to a wide range of current sensing applications.
- Tight Tolerance and Low TCR: These resistors boast a tolerance of 1% and a temperature coefficient of resistance (TCR) as low as 100ppm/°C, ensuring highly accurate and stable current measurements across varying temperatures.
Built for Durability and Reliability
The LRF4W series prioritizes robustness for demanding environments:
- AEC-Q200 Qualification: This qualification signifies the LRF4W's suitability for automotive applications, adhering to stringent quality and reliability standards.
- Surge Current Tolerance: The LRF4W can withstand a 100% over-current condition for 5 seconds, offering excellent surge protection and enhancing system reliability.
- Fault Tolerance: The combination of high surge tolerance and high-power density allows for a higher degree of fault tolerance to be built-in at the component level, safeguarding against potential system failures.
Optimized for Efficient Power Management
"The LRF4W thick-film SMT shunt resistor is a valuable addition to TT's portfolio of AEC-Q200 approved current sense resistors," said Stephen Oxley, Business Development Engineer at TT Electronics. "This new product empowers our customers to achieve accurate and surge-proof current measurement in PCB assemblies. This ultimately supports the development of products with reliable control of energy consumption."
