4BF1905-10RJI 数据手册
Tubular Vitreous Enamelled Wirewound Resistors 1600/1900 Series Welwyn Components • • • • Impervious lead free vitreous enamel coating Can be supplied with fixed, adjustable, tapped or low inductance winding Seven termination styles with choice of mounting arrangements Manufactured RoHS compliant Pb-free terminations* * Check status of stock when ordering General Information Vitreous enamelled wirewound resistors are capable of withstanding a higher dissipation size for size, than any other protected type; this is attributable to the higher operating temperature which the wire and enamel can withstand. Vitreous enamel provides exceptionally good protection to the wire element and is essentially impervious to moisture. The resistors can safely be used in harsh environmental conditions. The Welwyn range is based on thirteen sizes of tube, each of which has a recommended maximum dissipation which limits operating surface temperature to a maximum of 375°C. The stability and high reliability of Welwyn tubular vitreous resistors is a direct result of the best quality materials being used in their construction. High purity ceramic tubes have been matched with nickel chromium resistance wires and specially formulated enamel to ensure that the resistors can withstand repeated heat cycling without damage. Connections between the resistance element and end terminations are welded; other connections are brazed. Mounting devices are available which permit resistors to be mounted by both ends or by one end. Single ended mounting is recommended for applications which do not subject the resistor to shock or vibration. Ferrules and the F type mounting plug are anchored into the tubes with high temperature adhesive. Special requirements, for types or styles not described in this brochure, will be considered for economic quantities.

1. 物料型号: - 该文档描述的是Welwyn Components生产的1600/1900系列的管状玻璃釉包线绕电阻器。

2. 器件简介: - 这些电阻器具有无铅玻璃釉涂层,能够承受比其他任何保护型电阻器更高的单位体积耗散。它们能够在恶劣环境下安全使用,基于十三种尺寸的管子,每种尺寸都有推荐的最大耗散量,将操作表面温度限制在最高375°C。

3. 引脚分配: - 提供了七种端接样式和多种安装选择,包括焊接和铜焊连接。单端安装推荐用于不会使电阻器受到冲击或振动的应用。

4. 参数特性: - 电阻器的电气数据包括功率等级、电阻范围、限制元件电压、温度系数(TCR)、电阻公差、值、热阻和操作温度范围。例如,1601型号在70°C时的功率等级为1瓦特,电阻范围见表1。

5. 功能详解: - 这些电阻器由于使用高纯度陶瓷管和镍连接,具有出色的稳定性和高可靠性。它们可以用于承受重复热循环而无损伤。

6. 应用信息: - 电阻器可以水平安装,建议在未受阻的孔中垂直安装以优化散热。还提供了有关如何通过强制通风降低热点温度的应用说明。

7. 封装信息: - 提供了详细的物理数据表,包括各种型号的尺寸,并附有各种安装夹、支架和插头的图纸和尺寸。例如,1601型号的A最大尺寸为33.0mm,B最大尺寸为17.5mm等。
