简述我们常说的贴片电阻(SMD Resistor)叫"片式固定电阻器"(Chip Fixed Resistor),又叫"矩形片状电阻"(Rectangular Chip Resistors),是由ROHM公司发明并最早推出市场的。
特点是耐潮湿,耐高温,可靠度高,外观尺寸均匀,精确且温度系数与阻值公差小。
按生产工艺分厚膜(Thick Film Chip Resistors)、薄膜(Thin Film Chip Resistors )两种。
厚膜是采用丝网印刷将电阻性材料淀积在绝缘基体(例如玻璃或氧化铝陶瓷)上,然后烧结形成的。
我们通常所见的多为厚膜片式电阻,精度范围±0.5% ~ 10%,温度系数:±50PPM/℃~ ±400PPM/℃。
薄膜是在真空中采用蒸发和溅射等工艺将电阻性材料淀积在绝缘基体工艺(真空镀膜技术)制成,特点是低温度系数(±5PPM/℃),高精度(±0.01%~±1%)。
封装有:0201,0402,0603,0805,1206,1210,1812,2010,2512。
其常规系列的精度为5%,1%。
阻值范围从0.1欧姆到20M欧姆。
标准阻值有E24,E96系列。
功率有1/20W、1/16W、1/8W、1/10W、1/4W、1/2W、1W。
特性:•体积小,重量轻•适合波峰焊和回流焊•机械强度高,高频特性优越•常用规格价格比传统的引线电阻还便宜•生产成本低,配合自动贴片机,适合现代电子产品规模化生产使用状况:由于价格便宜,生产方便,能大面积减少PCB面积,减少产品外观尺寸,现在已取代绝大部分传统引线电阻。
