Current Sense Resistors
Current Sense Resistors - FAQS
Current sense resistors or shunts are low value parts used to convert current to a small, proportional voltage with the minimum of power loss. IBS Electronics has an extensive portfolio of current sense resistors with values extending below 1mO and rated at currents over 100A. For best accuracy these products should be connected by four connections, two for the current path and two for voltage sense, and four terminal types facilitate this.
Current-sense resistors, which come in a variety of shapes and sizes, are used to measure current in many automotive, power control, and industrial systems. When using very low value resistors (a few milliohms or less), the resistance of the solder becomes a substantial portion of the sense element resistance and adds significantly to the measurement error. High-accuracy applications often use 4-terminal resistors and Kelvin sensing to reduce this error, but these special-purpose resistors can be expensive. In addition, the size and design of the resistor pads play a crucial role in determining the sense accuracy when measuring large currents. We carry a series of current sensing resistor which characterized with miniaturization down to 01005 size, high power up to 3W, high precision, and low TCR. By developing the Metal technology including Metal Foil, Metal Strip, Welding ones and combining with the original thin film and thick film technology, current sense resistors manufacturers have developed a series of current sensing resistor which characterized with miniaturization, high precision, and low TCR. Furthermore, manufacturers offer a variety of processes which can cover a wide resistance range from 0.2mO to 10O, also can provide the most suitable resistance and rated power based on customer needs. Current Sense Resistors: Typical applications include snubbers and current sensing in power supply and electric motor control such as electric welding, heaters, power steering and many more. |
