Precision resistors have a maximum operating voltage and current beyond which the resistance changes, in some cases a lot, or the resistor can be damaged, such as overheating or burning. While some precision resistors have specified voltage and current ratings, the maximum power rating of most precision resistors is determined by their physical size. There are not a few companies capable of producing precision resistors, but many precision resistors are non-standard resistors, because the environments and products used by customers are very different, which leads to many customers encountering problems when purchasing precision resistors. Many stable, few resistor manufacturers will consider customers' problems in this regard.
Our common common resistors are generally composed of carbon and metal film resistors. The general power levels are 1/8 watt, 1/4 watt and 1/2 watt. Metal film resistors and carbon film resistors are more stable than carbon film resistors in terms of temperature changes and aging. Larger resistors dissipate more heat because they have a larger surface area. When high power ratings are required, wirewounds and resistors buried in sand (ceramic) can be used. However, in addition to these requirements, precision resistors require strict parameter restrictions on the accuracy, temperature drift and power of the resistors on many high-end instruments. Therefore, many customers propose the production mode of DIY precision resistors, which is what we call private customized precision resistors. Resistor.
From the perspective of precision resistor service customers, the electronic components industry has a wide range of downstream customers. Customers have multi-level product requirements for thin-type electronic components, and different products are designed, selected materials, production processes, and supporting services. There are differences in other aspects, so precision resistor companies also need to have the ability to provide a series of services such as new product development, customized production, and follow-up maintenance according to the actual needs of customers in the product production process. One-stop service is an important factor to measure the comprehensive competitiveness of the enterprise.
