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. Excellent solderability is proven, even after extended storage. They are suitable for automatic soldering using wave or dipping.The resistors are completely lead (Pb)-free, the pure tin plating provides compatibility with lead (Pb)-free and lead-containing soldering processes. The immunity of the plating against tin whisker growth, in compliance with IEC 60068-2-82, has been proven under extensive testing. The encapsulant is resistant to cleaning solvent specified in IEC 60115-1. The suitability of conformal coatings, if applied, shall be qualified by appropriate means to ensure the long-term stability of the whole system.APPROVALSThese resistors meet the safety requirements of:•UL1676 (510 kΩ to 11 MΩ); file no: E171160•IEC 60065, clause 14.2 a)•DIN EN 60065, clause 14.2 a)•VDE 0860, clause 14.2 a)•CQC, ChinaRELATED PRODUCTSFor a correlated range of Metal Film Resistors see the datasheet:“High Ohmic / High Voltage Metal Film Leaded Resistors”, /doc?30260For product that offers high power dissipation and metal oxide film technology see the datasheet:“High Power Metal Oxide Leaded Resistors”,/doc?20128Notes(1)The IEC 62474 list of declarable substances is maintained in a dedicated database, which is available at http://std.iec.ch/iec62474(2)The G lobal Automotive Declarable Substance List (G ADSL) is maintained by the American Chemistry Council, and available atVR25, VR37, VR68Vishay BCcomponentsFUNCTIONAL PERFORMANCEDeratingHot-Spot Temperature Rise ( T) as a Function of Dissipated PowerVR25VR37VR25, VR37, VR68 Vishay BCcomponentsMaximum allowed peak pulse voltage in accordance with IEC 60065, 14.2 a);50 discharges from a 1nF capacitor charged to Ûmax.; 12 discharges/min (drift ∆R/R≤ 2 %)VR25VR37VR25, VR37, VR68 Vishay BCcomponentsTemperature Rise ( T) at the Lead End (Soldering Point) as a Function of Dissipated Power at Various Lead Lengths after MountingVR25VR37VR25, VR37, VR68Vishay BCcomponentsTESTS PROCEDURES AND REQUIREMENTSAll tests are carried out in accordance with the following specifications:•IEC 60115-1, generic specification (includes tests)The test and requirements table contains only the most important tests.

波纹电阻材料
波纹电阻材料
波纹电阻材料是一种金属材料，通常是使用具有弹性的薄片材料制成，如不锈钢或铜合金。
它们的特点是表面具有波纹或波纹结构，使其能够具有较大的弯曲能力。
波纹电阻材料通常用于高温或高电流应用中，因为它们能够承受较大的热量和电流负荷。
波纹电阻材料的使用具有以下优点：
1. 高温下的稳定性：波纹结构可以提供更好的热量散射，有效降低材料温度，使其能够在高温环境下工作。
2. 低电阻温度系数：波纹电阻材料通常具有较低的电阻温度系数，使其能够在大范围温度变化下维持相对稳定的电阻值。
3. 高电流负荷能力：波纹电阻材料的结构使其能够承受较大的电流负荷，避免过热或损坏。
由于这些优点，波纹电阻材料广泛应用于各种领域，包括电子设备、汽车、航空航天等。
它们常用于电流限制、电流测量和电阻调节等电路中。
波纹电阻器 负载测试方法
波纹电阻器负载测试方法说实话波纹电阻器负载测试方法这事，我一开始也是瞎摸索。
我试过好多笨办法呢。
最开始我就简单地给它通上我觉得差不多的电流，然后看它的反应。
这就好比给一个人随便喂饭，根本不知道他到底能吃多少合适。
结果那电阻器一下子就发热得厉害，我都吓了一跳，这肯定是不正确的做法。
这就是一个失败的教训，不能这么盲目测试。
后来我就开始仔细研究相关资料。
在负载测试的时候，电源得选用稳定的。
这就像是给汽车加油，你得保证油的品质稳定对吧。
那电源不稳定，就好像一会儿加95号油一会儿加92号油，那车（这里类比电阻器）肯定会有异常反应的。
我不太确定波纹电阻器是不是和普通电阻器完全一样的测试方式，但我觉得基础的原理应该有相通之处。
我还尝试着逐步增加负载电流。
就像慢慢给一个容器注水一样，不能一下子倒太多。
比如说我先从比较小的电流值开始，然后在一段时间内观察电阻器上的一些参数变化，像电压啦、温度啦。
这个过程要很耐心，中间我还犯过错，我有一次以为观察一会儿没问题就加大电流太快了，结果发现电压瞬间有点波动，还好我及时停了下来。
我觉得在做波纹电阻器负载测试的时候，记录数据也很关键。
我专门弄了个小本子，把每次的电流值、相应的电压、测试时间还有电阻器的温度都记下来。
这就像医生要记录病人的病情变化一样，得有条有理。
还有就是测试环境，我不太确定温度和湿度到底对结果影响有多大，但我尽量让测试环境保持比较稳定的状态。
我做测试的时候是在室内，我就没开窗户避免外界环境变化太大。
等我觉得在一种负载电流下观察的足够久并且各个参数都稳定了，我才会继续增加电流再做下一轮测试。
对了，测试设备也要校准好。
我有一次就是没校准好电压表，测试出来的数据特别奇怪，后来发现是这个问题重新校准才对了。
所以啊，这些小的细节可一定得注意，都是我实实在在踩过的坑呢。
