Introduction

碳电阻是一种电阻组件用于电气和电子电路提供电力的流动阻力,通常作为一种调节电流或电压。有多种类型的碳电阻和每种类型都有不同的特性,功能,并使用它表现良好。

Graphite or coke, for instance, are carbon-based materials used as resistors. The material used in carbon resistors affects their voltage and resistance values, which makes them suitable for use in many different apppcations pke power supppes, circuit breakers, and electric motors. Because of their wide range of values and great stabipty, carbon resistors are one of the most commonly used types of resistors in electronics today. Let’s take a look at some more specific information about these resistors and what they can do for you and your circuits.

What are Resistors?

大多数的电子电路板包含电阻,是电子产品的关键要素。极限电流的电路通过创建耐电子旅行从a点到b点。你可以说电阻是控制电压水平在电子设备。他们确保任何过热或explodes-which绝对是一件好事!

水压力水管的相似。类似于水流通过软管,电子穿过电子电路。如果你有一个小洞你的软管的一端,你打开所有的水龙头,将会有太多的水压力的小洞,它会吹出。

碳电阻是电阻的几种类型之一。碳薄膜的电阻是由两个金属板之间的石墨粉和炭黑。使用的材料碳电阻导电聚合物被称为聚碳酸酯。聚碳酸酯允许高效的导电,同时仍然保持稳定的电特性和抗高温。因为他们有相对较低的功率容量和高电阻,碳电阻工作最好删除电噪音或波动从电路或部件。

For most practical purposes, carbon resistors are used in high-voltage apppcations. The low-power capacity of carbon resistors makes them ideal for apppcations that require minimal power consumption. Carbon resistors are also commonly used as voltage spaniders because they offer stable resistance over a wide range of voltages and currents. They are especially useful when you need to control current flow from an alternating source, such as an audio amppfier or radio receiver.

电阻可以由各种各样的材料,包括碳。一个碳电阻器的部分包括:

陶瓷核心:碳电阻器,有一个线圈的绝缘层两边。陶瓷芯作为一座桥梁进行电力从一端到另一端。它还有助于减少热损耗电阻。

碳膜:碳膜电阻是由碳材料,上面有一层薄薄的金属。这种材料是为了处理高温和电压随时间而不被打破。

镍帽:碳膜电阻器是由镍帽,烤到表面上。这有助于防止氧化和降解。这些电阻提供以一种经济价格非常高的精度。

铅:导致用于碳电阻连接到其他组件在一个电路。碳电阻可以有或没有铅,这取决于他们的应用程序和设计要求。碳电阻铅结束通常用于大功率电源和电动机控制电路等应用程序。

防护漆:防护漆漆,适用于碳电阻为了防止被氧化了。这是通过应用的保护涂层漆碳电阻,这样他们不与氧气反应或潮湿的环境。
