风华电阻编码规则
风华电阻编码规则是一种广泛应用于电子领域的编码规则,它通常用于将电阻值转换为二进制代码。
它是一种非线性编码规则,能够在有限的电阻范围内提供较高的精度。
风华电阻编码规则有多种不同的形式,其中最常见的是E系列和J系列。
E系列是英文E组列的缩写,它是基于对数的编码规则。
通常情况下,E系列电阻值以10的某个幂的形式表示,例如E6系列电阻包含6个不同的值,分别为:10Ω、
15Ω、22Ω、33Ω、47Ω和68Ω。
这种编码规则使得电阻值之间的间隔较为均匀,可以满足不同精度要求的电路设计。
另一种常见的风华电阻编码规则是J系列,它是基于线性的编码规则。
不同于E系列的对数划分,J系列的电阻值是通过等分电阻范围来确定的。
例如J12系列电阻范围从100Ω到10MΩ,共包含12个不同的值。
这种编码规则适用于一些特定的应用,如变压器和音频设备等。
风华电阻编码规则的优点在于能够提供多个不同的选项,从而满足各种不同的应用需求。
同时,由于编码规则的非线性性质,可以在较小的电阻范围内提供更高的精度和灵活性。
总之,风华电阻编码规则是一种在电子领域广泛使用的编码规则,通过将电阻值转换为二进制代码,提供了多个选项以满足不同的应用需求。
无论是E系列还是J系列,都能够在各自的范围内提供较高的精度和灵活性。
电阻器选型指导书前言固定电阻器选型规范用于方便开发人员对固定电阻器的选型和使用,能通过查阅此选型规范得到通用固定电阻器的基本选型原则,同时能使公司应用的电阻器向优选型号集中,减少项目数量,形成批量采购优势,既能保证质量又能降低成本和风险。
现公司用电阻器在MRP II 中有11个分类(0701~0711):0701 金膜电阻器(插装,有金属膜和金属氧化膜两类)0702碳膜电阻器(话机专用分类)0703 熔断电阻器(插装,涂覆型)0704 压敏电阻器(敏感电阻,本规范不讨论)0705 热敏电阻器(敏感电阻,本规范不讨论)0706 绕线电阻器(有水泥绝缘型、不燃性涂装和铝外壳封装三种)0707 电位器(可变电阻器,本规范不讨论)0708 集成电阻器(有插装、表面贴两类)0709 片状厚膜电阻器(SMD)0710 光敏电阻器(此分类暂无项目,尚未实际应用,本规范不讨论)0711 片状薄膜电阻器(SMD)在MRP II 中,优选等级用M标记的项目限制在公司电气使用,用T标记的项目限制在话机中使用。
不在公司技术的产品中使用。
电阻器的归一化方向为:(1)0701类金膜电阻器:1W以下功率优选金属膜电阻,1W及1W以上功率优选金属氧化膜电阻。
(2)0702类碳膜电阻器:为话机专用类别,公司技术不使用。
优选等级信息用“T”标记。
(3)0703类熔断电阻器:不推荐使用。
反应速度慢,不可恢复。
建议使用反应快速、可恢复的器件以达到保护的效果,并减少维修成本。
(4)0706类绕线电阻器:大功率电阻器。
(5)0708类集成电阻器:贴片化。
插装项目只保留并联式,插装的独立式项目将逐步淘汰,用同一分类(0708)的片状集成电阻器替代。
(6)0709类片状厚膜电阻器:在逐步向小型化、大功率方向发展,优选库会随着适应发展方向的变化而动态调整。
这类电阻器是小功率电阻的优选对象。
(7)0711类片状薄膜电阻器:建议使用较高精度类别。
不论那种电阻器,都不能采用边缘极限规格。
