Guoju has introduced PT series current sensing resistors with advanced precision temperature coefficient characteristics to enhance the stability of current sensing. It is especially suitable for high-end portable applications such as smart phones, netbooks and various portable storage products. . Guoju PT system current sense resistor has been certified by international manufacturers. After mass production in February 2009, shipments will begin in the second quarter. The launch of the PT series once again demonstrates Guoju's superior development capabilities for customized products and further increases the proportion of sales of special component products.

The PT series current sense resistors cover the 0402/0603/0805/1206/2010/2512 size range. Compared to the existing RL series, the Temperature Coefficient of Resistance (TCR) performance is significantly improved, with a minimum of 75ppm/°. C. In addition, the PT series features low resistance values ​​down to 100 milliohms. These features give the product outstanding performance and reliability, providing portable products with tight design and high functional convergence, such as smart phones, netbooks and more accurate current sensing.


Guoju RL series current sensing resistor products have been widely used in notebook computers, power supplies and mobile phones. Combining outstanding R&D, production technology and process, the PT series is introduced with leading-edge temperature coefficient characteristics to minimize the resistance drift. Future trends in current sense resistors will evolve toward smaller size, higher power, and lower temperature coefficient of resistance. Following the PT series, the company plans to introduce a version of the same size and resistance but twice the power to create a more robust product portfolio that offers customers complete size and power options.
