Our company's latest product is a series of ultra-precision power foil resistors. These resistors are specifically designed and manufactured for high-end electronic applications that require high precision and stability in power measurements.
One of the key features of this product line is their ultra-precision. These resistors are designed to have high-accuracy power ratings, which means more accurate measurements of power consumption in electronic circuits. This is achieved through the use of special materials and manufacturing techniques, which results in low tolerance and low drifts.
In terms of power rating, our Ultra-Precision Power Foil Resistors provide a range of power ratings from 0.01W to 5W, making them well suited for a wide range of applications. Additionally, they can operate in a temperature range of -55°C to +150°C, ensuring reliable and stable performance even in harsh environments.
Â
Another key feature of our Ultra-Precision Power Foil Resistors is their low temperature coefficient of resistance (TCR) which makes them ideal for use in high-precision applications that require minimal changes in electrical resistance over a range of temperatures.
Furthermore, these resistors are thin and flexible, which makes them easy to integrate with other electronic components. The product line offers customization options, including different dimensions, shapes, and power ratings, which can be tailored to meet specific customer requirements.
In conclusion, our ultra-precision power foil resistors are an excellent choice for high-end electronic applications that require accurate and stable power measurements. Their low tolerance, low drift, low TCR, and wide range of power ratings and temperature capabilities make them a versatile component for a variety of applications. Our company's commitment to superior quality and customization options ensure that our customers will receive the most reliable and suitable product for their specific needs.

Rated Power Note- RNG6040 Series resistance connected to a suitable radiator for use. The maximum internal temperature is 130°C. Using the following formula: Where: RθH= thermal resistance of the radiator (K / W) RθR = electric resistance of thermal resistance (K / W) TMAx = maximum resistance maximum working temperature TA = Ambient temperature of radiator (℃) P = power of resistor (W) |

For low resistance resistance (less than 10 Ω), the increase in the resistance and temperature coefficient of the copper pin exceeds the resistance itself. A four-legged Kelvin connection is recommended, as shown in the figure below. The load current on the V-pin will cause a measurement error.
