Finding an Excellent Power Resistor Manufacturer
Resistors are small systems which are essential in the control of resistance in electrical circuits. Resistor manufacturers have an extended range of both variable and fixed resistors. Depending on your needs and objectives, you can always select from the different resistors which are in the market such as variable resistors, braking resistors, power resistors, shunt resistors and the wire-wound resistors. Precision resistors demand on the increase, and that is why a majority of resistor companies are now focusing on having a diversified range of products that are altered to suit a client’s needs. The resistor companies are always open to conversations so that you can tell them the kind of product that you want. You should not forget to confirm that the resistor you bought will be appropriate for your needs.
To make your search for the best resistor for your needs easy, you need to recognize some of the difficult factors that are involved in the construction of the resistors and the various characteristics that they have. As earlier stated, resistors are not the same, and that is why you need to understand your power needs before you decide to purchase a resistor. For proper functioning of electrical circuits, there must be a resistor, and that is why it is important to know which one will fit perfectly into the system during the designing process. There are some resistors that will not function properly when the circuit temperature becomes excess, and that is why you need to check the power rating of the resistor. You need to purchase high-powered resistors if they are used for equipment located in high ambient temperatures. For industrial applications, make sure that you choose high-wattage resistors.
When buying resistors for use, a good resistor manufacturer will show you a data sheet to show you the temperatures at which the resistors should work, and that should make your selection easier. The temperature ratings of wire wound resistors varies depending on the coating material, physical nature of the resistor and the surface area. Normally, a tubular clay and resistance curving are the ones used in designing the wire wound resistors. The winding is not left naked, but instead, there is a coating which is placed on it to ensure consistent functioning in harsh environments or weather.
The reason, why silicon material continues to be used by a majority of resistor manufacturers, is because it is reliable. If a resistor is designed to operate at low temperatures and the coating material changes quickly, then that affects operation such that there will be inconsistencies in power supply. Maximum voltage is an important factor when choosing the most suitable resistor for a certain application especially for high voltages.
