DC 50A 75mV Current Shunt Resistor for Amp Meter Gauge

This dc 50a 75mv current shunt resistor is a ‘must-have’ component for all dc 50a current ammeter. Sensing the current flow is an important thing in many power and general electronics applications. Often, current sensing  required to monitor and control an application, for example, a battery charger circuit requires a current sensing technique to properly charge the battery and to determine the charge current from the driver, controller perspective.

Depending on the type of application, there many types of sensors with different current sensing techniques  used to measure or detect current flow. The most commonly used and cost-effective solution for current sensing is the shunt current sensor method. The shunt current sensor, also known as a sense resistor. It is similar to a basic resistor but with very low resistance value. In this article, we will more about this current sensor, how they work, its types, and how you can use one in your designs.

Shunt resistors are a special type of resistors. It different from the traditionally used resistors in electronic circuits. The generic resistors are used for the very low current of operations. And generally used in standard ambient temperatures such as 0-85 Celsius. But, shunt resistors have a very wide range of temperature coefficients due to the huge current flow through it.
