Visresistor LRJ alloy sampling resistor, with its unique alloy material and excellent performance, is very popular in equipment applications, the following Shunhai technology LRJ series resistor material, characteristics, parameters and selection are introduced in detail, to help engineers better understand and choose Visresistor.
VISHAY resistor LRJ series introduction
VISHAY resistor LRJ series uses a special alloy material, this material not only has the characteristics of impulse current resistance, but also can withstand high current through, is a true zero resistance resistance. The series of resistors have superior heat dissipation performance, good stability and small error, and are widely used in various electronic circuits requiring high precision and high stability.
VISHAY resistors Main parameters of LRJ series resistors
Resistance value: The resistance value of VISHAY resistor LRJ series is 0R, that is, the theoretical zero resistance value, in practical application, due to the limitations of production process and measurement technology, the resistance value will have a certain error range, but the error is very small, the impact on the circuit performance can be ignored.
Accuracy: The precision of the LRJ series resistor is 5%, which refers to the allowable deviation between the actual resistance value of the resistor and the nominal resistance value during the production process. The higher the accuracy, the closer the resistance value of the resistor is to the nominal value, and the more stable the performance of the circuit.
Package: The LRJ series resistors are available in a variety of package specifications, including 1206 and 2010, and the selection of package specifications should be determined according to the space and assembly requirements of the board. The resistance of 2010 package is larger, better heat dissipation performance, suitable for high-power circuits; The resistance of the 1206 package is smaller and suitable for boards with limited space.
Rated current: The rated current of the LRJ series resistor has two specifications: 40A and 57A, and the rated current refers to the maximum current value that the resistor can withstand when working for a long time. When selecting a resistor, ensure that the actual current in the circuit does not exceed the rated current of the resistor to prevent the resistance from overheating and damage.
Ambient temperature: The ambient temperature range of the LRJ series resistor is -55℃ ~ +155℃, in this temperature range, the resistance value and performance of the resistor can remain stable. If the working environment of the circuit exceeds this temperature range, it may affect the performance of the resistance, and even cause resistance damage.
VISHAY Resistor LRJ Series selection guide
When choosing VISHAY resistor LRJ series, first determine the required resistance and accuracy according to the needs of the circuit, for most applications, 0R resistance and 5% accuracy is enough to meet the requirements, according to the space and assembly requirements of the board to choose the appropriate package specifications. If the current in the circuit is large, the resistance with larger rated current should be selected; If the working environment temperature of the circuit is high or low, a resistor with a wide range of ambient temperature should be selected, and factors such as the cost and availability of the resistor need to be considered to ensure the economy and feasibility of the selection.
