英语翻译
You will notice with E12 values that each succeeding value falls within the plus/minus 10% of the previous values.
This stems from the real old days when resistances were stated as within 20% tolerance(accuracy).
Later values of plus/minus 5% tolerance led to the E24 range of resistance.
Quite common today are 2% tolerance metal films types but for general purpose use we tend to stick to E12 values of resistance in either 1%,2%or 5% tolerance.
Cost is the determining factor and many retailers now stock the 2% range of resistance as a standard to accommodate stocking levels and also at reasonably low cost.

你会发现与E12的价值观,每个成功的价值在加/减10%,前值下降.
这源于)由电阻时分别为20%容差之内(准确度表示真正的黄金岁月.
后来的正/负5%的公差值导致抵抗E24范围.
今天是很常见的金属薄膜2%容差一般用途的类型,但我们倾向于坚持使用在任1%,2%或5%的耐抗性E12的价值观.
成本是决定因素,许多零售商现在股票作为标准,以适应放养,并在合理的水平低的成本,抵抗2%之间.
