Introduction to Walter HFCL series current sensing resistors

The Walter HFCL series current sensing resistor is a four terminal alloy resistor mainly used for simultaneously collecting current and voltage, with high reliability and low-temperature drift characteristics. These resistors are usually made of alloy materials, which can provide high manufacturing accuracy and stability, and can effectively eliminate the effects of resistance heating and contact resistance on measurement results, thereby improving measurement accuracy

The size range of Huade HFCL series current sensing resistors is wide, ranging from 0603 to 3921, with resistance values covering 0.5m Ω to 25m Ω and power ranging from 0.33W to 4W. These resistors have different temperature coefficients (TCR), with an accuracy of ± 0.5% to ± 1%. Some models, such as HFCL1206M1W0R020D and HFCL1206M1W0R025F, have resistance values of 0.02 Ω (2mR) and 0.025 Ω (25mR), respectively, with a power of 1W and an accuracy of ± 0.5% and ± 1%

The Huade HFCL series resistors are widely used in various electronic devices, such as power management, amplifiers, oscillators, filters, regulators, voltage regulators, etc., due to their high precision and stability. They are also widely used in fields such as automotive electronics, aerospace, etc., for high-precision measurement and control systems of resistance values

The four terminal design used in the Huade HFCL series resistors can reduce the mutual interference between current and voltage and improve measurement accuracy. In addition, these resistors can maintain stable resistance values and electrical performance in high-temperature environments, making them suitable for various high-temperature application scenarios

In summary, the Walter HFCL series current sensing resistors have become one of the important components in the electronics industry due to their high precision, stability, and excellent performance in various application scenarios. Whether in power management or precision measurement systems, the Huade HFCL series resistors can provide reliable performance guarantees< span class="blink-line">
