Image result for Custom Resistors  istock
There are different types of resistors in the market, and one of them is the wire wound resistor. This is one of the oldest resistors that exists, and it is used for many functions. All the wire wound resistors are designed with the same concept of a metallic wire that has been coiled around the center of an insulating material. You need to note that there are two types of wire wound resistors and these are the power resistor and the precision wire wound resistor. Read more about Custom Resistors from power resistors. The precision wire wound resistors are utilized in precise measuring bridges and calibration devices.
The precision resistors can have a tolerance that varies from one to another. These resistors also have a good temperature coefficient which is good when you compare to other metal film resistors. The precision wire wound resistors can be coated with materials because they are designed for temperature increases. On the other hand, there are power wire wound resistors which can be categorized according to the coating material that has been used. One of the coating materials which is used is silicon resins and can be utilized for lowest discharge ranges. The second kind of coating is porcelain enamel, and it has been used for a long time.
The porcelain enamel provides good insulation at low temperatures. The reason why it remains less common is that the insulation is less when at higher temperatures. Ceramic coating is another coating type, and it also protects the wire. This coating provides an efficient energy release and also offers excellent physical protection. Those resistors that have a large power rating have an aluminum case. This provides a large surface area that can spread the heat hence allowing the resistor to handle more power without getting weak. Click precision resistor company to read more about Custom Resistors. To achieve high power dissipation, usually, the resistor needs to be put on a metallic surface to achieve appropriate heat transfer.
A precision resistor company needs to have a good understanding of the resistor application before deciding on the film to use for coating. The processing technology and available materials also decide the film of the resistor. There are various resistor manufacturing companies, and you need to look for that one which will guarantee you of high-quality resistors. For a good performance resistor, it is advisable that you buy it from a reputable manufacturer who has been in the industry for a long time. Another key consideration when buying best performance materials is the cost.
