Manganese-copper Low Ohmic Resistors Open Air Metal Alloy Sampling Resistor

Low ohmic resistors, particularly metal alloy sampling resistors, play a crucial role in current sensing applications across various electronic systems. These resistors are designed to measure electric current by utilizing the voltage drop across them, following Ohm's law.

Key Characteristics of Low Ohmic Metal Alloy Sampling Resistors

1. Material Composition: These resistors are often made from alloys such as manganese-copper or constantan, known for their low resistance values and high precision. Manganese-copper wire resistors, for example, are widely used in applications requiring accurate current sensing due to their stability and low temperature coefficients.

2. Resistance Values: Typical resistance values for these sampling resistors range from 1 milliohm to 15 milliohms, making them suitable for high-current applications while minimizing power loss. The low resistance ensures that the voltage drop across the resistor is minimal, which is essential for maintaining circuit integrity.
