1. 物料型号: - RW系列:包括RW1、RW2、RW2S、RW3、RW3S、RW5、RW10等不同型号,分别对应1瓦到10瓦的功率等级。

2. 器件简介: - RW系列电阻器采用独家自动化系统制造,成本节约显著。陶瓷芯性能优于传统玻璃纤维芯,特别是在过载能力、温度系数、噪声特性和负载寿命稳定性方面。涂层防火,具有出色的耐湿和耐溶剂性能。

3. 引脚分配: - 提供水平和垂直的引脚形式,具体尺寸和选项在文档中有详细说明。

4. 参数特性: - 电阻范围:0.01Ω至25KΩ。 - 标准公差为5%,也提供2%和10%的公差选项。 - 可提供低电感(Option X)、增强脉冲能力(Option P)、防火易熔(Option FF)、低热EMF(Option E)和防火涂层(Option F)等选项。

5. 功能详解: - RW系列电阻器由于全焊接线绕结构而具有固有稳定性。 - 温度范围:-55°C至+275°C。 - 温度系数:1及以上为100ppm/°C,0.05至0.99为300ppm/°C,低于0.05为600ppm/°C。 - 绝缘电阻:1000兆欧姆。 - 标记:色带(或字母数字)表示阻值和公差。 - 耐湿性:±2%AR。 - 热冲击:±1%AR。 - 耐压:500V。 - 负载寿命:额定功率的2%(Option FF为3%典型值)。 - 过载:5倍额定功率,5秒(Option FF为2倍功率,5秒)。

6. 应用信息: - Option FF易熔电阻器可用于0.1Ω至2.4KΩ(RW1最大1.2KΩ)。 - 故障水平必须适合安全打开电阻器。Option FF部件设计为在15倍额定功率下20秒内熔断(如果≥1Ω),如果是<1Ω则为20倍(如果故障水平是这个水平的两倍,则更能保证快速熔断时间)。 - 最大故障不得超过200倍功率额定值或电压额定值(以较低者为准,可提高水平)。

7. 封装信息: - 提供了多种封装选项,包括批量包装(B)、水平胶带和卷轴(T)以及垂直胶带和盒子(APN)。
