VISHAY metal film resistor Selection guide
When choosing VISHAY metal film resistor, it is necessary to determine the appropriate model and parameters according to the actual needs of the circuit, considering the size and accuracy of the resistance value, to ensure that the resistance can meet the precise resistance value needs of the circuit, pay attention to the power and voltage level, to ensure that the selected resistance can withstand the power consumption and voltage shock in the circuit, but also need to consider the size and packaging form of the resistor. To facilitate layout and welding on the circuit board. We should also pay attention to the stability and reliability of the resistance, and choose brand products that have been verified by the market and have a good reputation.
