A homogeneous film of metal alloy is deposited on a high grade ceramic body and conditioned to achieve the desired temperature coefficient. Plated steel termination caps are firmly pressed on the metalized rods. Mostly, a special laser is used to achieve the target value by smoothly cutting a helical groove in the resistive layer without damaging the ceramics. Connecting wires of electrolytic copper plated with 100 % pure tin are welded to the termination caps. The resistor elements are covered by a light blue protective coating designed for electrical, mechanical, and climatic protection. Four or five color code rings designate the resistance value and tolerance in accordance with IEC 60062.Yellow and gray are used instead of gold and silver because metal particles in the lacquer could affect high-voltage properties.The result of the determined production is verified by an extensive testing procedure performed on 100 % of the individual resistors. Only accepted products are stuck directly on the adhesive tapes in accordance with IEC 60286-1 or for the radial versions in accordance to IEC 60286-2.MATERIALSVishay acknowledges the following systems for the regulation of hazardous substances:•IEC 62474, Material Declaration for Products of and for the Electrotechnical Industry, with the list of declarable substances given therein (1)•The G lobal Automotive Declarable Substance List (GADSL) (2)•The REACH regulation (1907/2006/EC) and the related list of substances with very high concern (SVHC) (3) for its supply chainThe products do not contain any of the banned substances as per IEC 62474, G ADSL, or the SVHC list, see /how/leadfree.Hence the products fully comply with the following directives:•2000/53/EC End-of-Life Vehicle Directive (ELV) and Annex II (ELV II)•2011/65/EU Restriction of the Use of Hazardous Substances Directive (RoHS) with amendment 2015/863/EU•2012/19/EU Waste Electrical and Electronic Equipment Directive (WEEE)Vishay pursues the elimination of conflict minerals from its supply chain, see the Conflict Minerals Policy at /doc?49037.ASSEMBLYThe resistors are suitable for processing on automatic insertion equipment and cutting and bending machines.

七、结论1. 总结ri80型玻璃釉瞙固定电阻器比热容的研究成果；2. 展望未来固定电阻器比热容研究的发展方向。
八、比热容的概念及其在固定电阻器中的作用分析比热容是指物质单位质量在温度变化时吸收或放出的热量的大小，通常用符号C表示。
在固定电阻器中，比热容的重要性不言而喻。
电阻器在工作过程中会受到外部环境温度的影响，而比热容的大小决定了电阻器对温度变化的响应能力。
一般来说，比热容越大，电阻器在受到热量影响时温度变化越缓慢，稳定性越好。
比热容是影响固定电阻器稳定性和性能的重要因素之一。
在固定电阻器中，因为电阻器的主体结构是由电阻材料和外部封装材料组成的，在温度变化时，这些材料会受到热胀冷缩的影响，从而导致电阻值发生变化。
而比热容就是在描述材料在温度变化时对热量的反应能力，从而影响了电阻值的稳定性。
了解并研究固定电阻器材料的比热容特性，既有助于改善固定电阻器的温度特性，也有助于提高电阻器的稳定性和精度。
在实际应用中，通过研究固定电阻器材料的比热容特性，可以为固定电阻器的设计和生产提供重要的参考依据。

电阻及其识别
热敏电阻
• PTC热敏电阻是一种典型具有温度敏感 性的半导体电阻,超过一定的温度(居里温 度)时, 它的电阻值随着温度的升高呈阶跃 性的增高.
压敏电阻
• 压敏电阻用字母“MY”表示，如加J 为家用，后面的字母W、G、P、L、H、 Z、B、C、N、K分别用于稳压、过压保 护、高频电路、防雷、灭弧、消噪、补 偿、消磁、高能或高可靠等方面。压敏 电阻虽然能吸收很大的浪涌电能量，但 不能承受毫安级以上的持续电流，在用 作过压保护时必须考虑到这一点。
常用电子元件：电阻器
金属膜电阻器（RJ）: 外形与碳膜电阻器相似，只是在碳棒表面用真空蒸发或烧渗法制成金属膜。 特点：金属膜电阻体积更小，除具碳膜电阻的特征外，比碳膜电阻精度更高， 热稳定性更好，噪音更低，阻值范围更高（几Ω －几百MΩ ） ，可用于高频电路。 价格贵。 用途：主要用于精密仪表、通讯设备,自动控制设备和高档家用电器。 外表一般涂红漆或棕漆。
三号码ＤＤＭ:(误差5%)
• 用三位数字表示阻值的大小； 三位数的前两位是有效数字， 第三位是有效数字后面0的个 数； 范例 ： ①：203=20 000 W， 即20k W； ②：100＝10100W= 10 W，即10 W； ③：562=5 600 W，即5.6k W；

合金类
• （1）线绕电阻（型号：RX）。将康铜丝或镍铬合金丝 绕在磁管上，并将其外层涂以珐琅或玻璃釉加以保护。 线绕电阻具有高稳定性、高精度、大功率等特点。温度 系数可做到小于10-6/℃，精度高于±0.01％，最大功率 可达200W。但线绕电阻的缺点是自身电感和分布电容 比较大，不适合在高频电路中使用。 • （2）精密合金箔电阻（型号：RJ）。在玻璃基片上粘 和一块合金箔，用光刻法蚀出一定图形，并涂敷环氧树 脂保护层，引线封装后形成。该电阻器最大特点是具有 自动补偿电阻温度系数功能，故精度高、稳定性好、高 频响应好。这种电阻的精度可达±0.001％,稳定性为 ±5×10-4％/年，温度系数为±10-6/℃。可见它是一种 高精度电阻。
