Metal foil resistors are manufactured using advanced processes, allowing precise control of resistance values. Their accuracy typically reaches ±0.5% or even higher, meeting the requirements of high-precision current sensing.
Metal foil resistors have a stable structure that is not easily affected by external environmental factors such as vibration or shock. They are capable of maintaining consistent resistance values and performance over time, ensuring the reliability of current sensing.
Metal foil resistors generate very little noise during operation, which is especially important for noise-sensitive circuits or high-precision measurement systems, helping to avoid interference with measurement results.
They can operate effectively across a wide temperature range, typically from -55°C to +125°C or even broader, maintaining strong performance in various working environments.
Metal foil resistors generally have high power handling capacity, allowing them to withstand large currents. They maintain reliable performance even under high power, with low risk of overheating, making them suitable for current sensing in high-power circuits.
In high-frequency circuits, metal foil resistors perform well due to their low parasitic inductance and capacitance, minimizing the impact on high-frequency signals and enabling accurate high-frequency current detection.
