现代电子设备的应用范围越来越广,使用条件也日趋成熟.特别是军工产品,不但会在各种地区(6g热带、沙漠、高山和海洋等)使用.而且会在特殊情况下(如 高速运动条件下)使用,这就要求电阻器具有能够适应各种恶劣环境的能力.如耐高温和低温、耐潮湿、耐低气压、耐辐射、耐盐雾和霉菌、耐振动和冲击等. 性能参数电阻柜性能参数包括额定功耗、标称阻值及允许偏差、电阻温度系数、高频特性、非线性和电流噪声、极限电压等方面.这些参数分别从某一方面在一定程 度上反映出该电阻柜的质量好坏,
The application scope of modern electronic devices is becoming increasingly wide, and the usage conditions are also becoming more mature Especially for military products, they are not only used in various regions such as tropical areas, deserts, mountains, and oceans And it will be used in special situations (such as high-speed motion conditions), which requires resistors to have the ability to adapt to various harsh environments Such as high and low temperature resistance, moisture resistance, low pressure resistance, radiation resistance, salt spray and mold resistance, vibration and impact resistance, etc Performance parameters of the resistor cabinet include rated power consumption, nominal resistance value and allowable deviation, temperature coefficient of resistance, high-frequency characteristics, nonlinearity and current noise, limit voltage, and other aspects These parameters reflect to some extent the quality of the resistor cabinet from a certain aspect,
并直接影响使用该电阻柜的电路的功能.小型化 电子设备的轻便、紧凑和小巧的发展要求,在很大程度上属于元件的小型化.为了适应这一发展趋势,各类新型的片式元件正在不断涌现.这使电子设备变得小、 薄、轻. 除了上述要求,还要求电阻柜的生产工艺性好、成本低、价廉等.电阻路要满足上述基本要求,达到优质、高产、低消耗,就必须在原材料、生产设备、结构和制造 工艺上进行穆新,不断采用新材料、新设备、新结构和新工艺,不断提高生产的机械化和自动化程度。
And directly affect the functionality of the circuit using the resistor cabinet The development requirements for lightweight, compact, and small electronic devices largely belong to the miniaturization of components In order to adapt to this development trend, various new types of chip components are constantly emerging This makes electronic devices smaller, thinner, and lighter In addition to the above requirements, it is also required that the production process of the resistor cabinet is good, the cost is low, and the price is affordable To meet the basic requirements of high quality, high yield, and low consumption, the resistance circuit must undergo innovation in raw materials, production equipment, structure, and manufacturing processes, continuously adopting new materials, equipment, structures, and processes, and continuously improving the mechanization and automation level of production.
