Current Sense Resistors

With a relatively low temperature coefficient—typically between ±50 ppm/°C and ±100 ppm/°C—the resistance value changes very little across different temperature environments. This effectively reduces the impact of temperature on measurement results, ensuring accurate current detection.

Metal film resistors have low parasitic capacitance and inductance, allowing them to maintain good electrical performance in high-frequency circuits with minimal signal distortion. They are well-suited for high-frequency current sensing.

The resistor material and manufacturing process result in low operational noise for metal film current sensing resistors, which helps improve signal quality—especially important in noise-sensitive circuits.

These resistors have a certain power-handling capability, allowing them to be used in circuits with various power levels while maintaining stable performance within the rated power range.

The thin-film structure gives them a relatively small footprint, making them easy to install on space-constrained circuit boards and supporting miniaturization and integration of electronic devices.

Compared to some high-precision specialty resistors, metal film current sensing resistors have lower manufacturing costs. While meeting performance requirements, they offer good value for money and are suitable for large-scale production and application.
