Generally, a resistor is a passive electrical component that functions by creating a resistance to the flow of current in electronic circuitry. If you did Physics back in high school or took an engineering-related course in college, then most probably you may have come across it. Resistors come in different forms and types ranging from variable resistors, rheostats, shunt resistors, wire-wound and also power resistors.
Occasionally, a client may need to use a resistor with some unique specifications that are not manufactured en masse. In such a case, they may approach a resistor manufacturing company and make a special request to have a resistor(s) manufactured that meets their specific requirements. Such a resistor is known as a custom resistor and the process of its production is called custom resistor manufacturing. Due to the low volume in the demand of custom resistors as compared to conventional types of resistors, most major manufacturers shy away from undertaking the task of custom resistor manufacturing which is usually picked up by the smaller manufacturing companies.
Custom resistors are known to feature resistances of 5 Ohms to 50 Ohms in cases that are as small as the 0402 size. They also possess superior voltage handling capabilities. Custom resistors can also have some very tight tolerances of around 0.1%, high stability and low-temperature coefficient of resistance voltage controlled resistor (VCR).
Custom resistors are designed for bespoke applications in which most resistors cannot suffice. These could be anything from extreme heat conditions or harsh physical and environmental conditions that a normal resistor would not survive in. This unique ability offers a huge benefit to manufacturers of products with unique requirements which cannot be met by the usual kind of resistors. Due to the unique specifications that are required in the manufacture of these resistors, the manufacturers first need to get a clear requirement specification from the customer before embarking on the custom resistor design. These resistors are designed to perform over a long period of time without suffering from performance degradation.
Another key benefit of custom resistor manufacturing is that they are able to cater for the replacement needs of obsolete devices whose resistors the major manufacturers may consider to be commercially unviable to continue manufacturing. The custom resistor manufacturers step in to ensure that these devices do not necessarily get grounded for lack of replacement resistors whenever they are needed. A specific type of custom resistor that is often used in this way is the custom thick film resistor. The use of custom resistors is normally used as a stop-gap measure to address a specific need before design modifications are made to ensure that a particular circuit can be served adequately by a standard resistor.
