Medical and military equipmentDESCRIPTIONThe resistors are constructed in a high grade ceramic body (aluminum oxide). Internal metal electrodes are added at each end and connected by a resistive paste that is applied to the top surface of the substrate. The composition of the paste is adjusted to give the approximate resistance required and the value is trimmed to nominated value within tolerance which controlled by laser trimming of this resistive layer.The resistive layer is covered with a protective coat. Finally, the two external end terminations are added. For ease of soldering the outer layer of these end terminations is a Tin (lead free) alloy.Fig 1.

ExampleFUNCTIONAL DESCRIPTIONProduct characterizationStandard values of nominal resistance are taken from the E96&E24 series for resistors with a tolerance of ±1%,±5%. The values of the E96/E24 series are in accordance with “IEC publication 60063”.DeratingThe power that the resistor can dissipate depends on the operating temperature; see Fig.2MOUNTINGDue to their rectangular shapes and small tolerances, Surface Mountable Resistors are suitable for handling by automatic placement systems.Chip placement can be on ceramic substrates and printed-circuit boards (PCBs).Electrical connection to the circuit is by individual soldering condition.The end terminations guarantee a reliable contact.SOLDERING CONDITIONThe robust construction of chip resistors allowsthem to be completely immersed in a solder bathof 260︒C for 10 seconds. Therefore, it is possibleto mount Surface Mount Resistors on one side ofa PCB and other discrete components on thereverse (mixed PCBs).Surface Mount Resistors are tested forsolderability at 235︒C during 2 seconds. The testcondition for no leaching is 260︒C for 30 seconds.Typical examples of soldering processes thatprovide reliable joints without any damage aregiven in Fig 3.Fig 3.

厚生金属电阻厚生金属电阻是一种常见的电子元件，它在电路中起着限制电流、稳定电压和改变电阻值的作用。
作为一种重要的电阻器，厚生金属电阻在各个领域都有广泛的应用。
厚生金属电阻的特点之一是其材料的选择。
它通常由金属铜、镍、铬等材料制成，这些材料具有良好的导电性和稳定性，能够在不同的工作环境下保持稳定的电阻值。
此外，厚生金属电阻还具有较高的功率耗散能力，能够承受较大的电流，不易受到过载或过热的影响。
厚生金属电阻的工作原理是基于电阻效应。
当电流通过厚生金属电阻时，金属材料内的电子会受到电阻的阻碍，导致电子的运动速度减慢，进而产生电阻。
根据欧姆定律，电阻值与电流成正比，与电压成反比。
因此，可以通过改变电流或电压来改变厚生金属电阻的阻值。
厚生金属电阻常用于电子电路中的限流电阻。
在电路中，为了保护其他元件免受过大的电流损害，需要加入适当大小的限流电阻。
厚生金属电阻由于其稳定性和功率耗散能力较强的特点，常被用作限流电阻。
通过选择合适的电阻值，可以实现对电路中电流的精确控制。
厚生金属电阻还常用于稳压电路中。
在一些需要稳定电压输出的场合，如电源、稳压器等，需要通过电阻来实现电压的稳定。
厚生金属电阻由于其稳定的电阻值和耐高温的特点，能够在这些场合中起到很好的稳压作用。
通过在电路中串联厚生金属电阻，可以有效地限制电压的变化范围，从而保证输出电压的稳定性。
厚生金属电阻还可以用于测量电流和电压。
在电路测试和仪器仪表中，常需要对电流和电压进行测量。
厚生金属电阻可以作为电流表和电压表的内部电阻，通过测量其上的电压降或电流值，来间接测量电路中的电流和电压。
由于厚生金属电阻的稳定性和精确性较高，能够提供较为准确的测量结果。
厚生金属电阻作为一种重要的电子元件，具有广泛的应用领域。
它可以用于限流、稳压、测量等方面，起到稳定电流、稳定电压和改变电阻值的作用。
在设计电子电路或选择电阻元件时，我们可以根据具体的需求和要求，选用合适的厚生金属电阻，以实现电路的稳定运行和精确控制。
