5色环电阻值在线计算器

5色环电阻值在线计算器是一种工具,用于计算电阻器元件的电阻值。它可以通过输入电阻器的颜色编码,自动计算出电阻器的电阻值,并且通常会给出该值的百分比和功率额定值。电阻器通常由一个绕有电阻线的陶瓷或金属筒组成,并且在筒的外部有几个彩色的环。这些环的颜色是按照一定规则排列的,每个颜色代表一个数字或一个乘数。通过对这些颜色进行解码,可以得到电阻器的电阻值。5色环电阻值在线计算器一般要求输入电阻器的颜色编码,并且可能还需要提供其他参数,例如电阻器的额定功率或百分比误差。根据这些输入,计算器将自动计算出电阻器的电阻值,并显示在屏幕上。需要注意的是,5色环电阻值在线计算器只能处理标准的5色编码电阻器,而对于其他类型的电阻器(例如6色环电阻器或SMD电阻器),可能需要使用不同的计算器或者手动计算。此外,虽然5色环电阻值在线计算器非常方便和易用,但在实际电路设计中,仍需要注意选择适当的电阻值和功率额定值,并进行充分的测试和验证。

This content is a five-color ring resistance calculator, which can easily identify the five-color ring resistance, do not know how to look at the five-color ring resistance can also be calculated resistance value, there are five-color ring resistance reading and five-color ring resistance expression.


The reading of five color ring resistance and the expression of five color ring resistance

Example: 5 ring resistance in turn: red Huang Hong black gold read 242 ohm. The error is ±0.5%
Example: the 5 ring resistance in turn is orange, white, yellow, red and silver, and the reading error is 39400 =39.4K, the error is ±10%
Example: 5 ring resistance The order is orange orange red gold red, orange orange red is 332 ohm, multiplied by 0.1=33.2 Omega error is±2%
From above, we must pay attention to the fourth color ring as gold or silver, because it is the negative number of multiplication.

About the error rate: the software error rate must be multiplied by 100, such as the number of calculated error shows 0.02 multiplied by 100 = 2%.
