A Brief Overview about Choosing the Right Electronic Resistors for Your Application Also known as the passive components, the resistor is a component that is precisely designed for finding the values of resistance in the different electronic circuit. It is used in electronic circuits to reduce the current. These electronic components work in accordance with Ohm’ law and are utilized for a wide range of functions such as:
Time control of rising/falling rhythms Current limiting applications Current sensing functions Attenuation of signals Capacitor bleeding Balancing voltages
In order to choose the right resistors for your specific applications or functions, you need to consider a number of parameters, which includes: Power rating Power rating is one of the first things to consider when you are selecting a resistor for any specific application. While still being compliant with specifications, a resistor must be capable of coping with dissipation. The specifications sheet provided by the vendor must be viewed cautiously if the operating area is a high temperature. You should also analyze whether the power rating is specified with relation to the ambient air and termination or the temperature of the heat sink. Temperature Coefficient of Resistance (TCR) Due to self-heating as well as due to other heating occurring in the proximity of the device, the ohmic value of a resistor can change significantly. It is an issue if the resistor selected uses the drop in voltage as an indicator of the current flow. Due to the TCR-affected ohmic change, the inaccuracy of the reading could increase significantly. Voltage rating It is used in high-voltage applications with enormous potentials across their leads reaching into thousands of volts. Before buying the resistors from reliable wholesale electronic resistor supplier, you should ensure that the resistor is suitable for the current voltage and are independent of the current and power levels.
