电(dian)(dian)(dian)(dian)阻(zu)(zu)在电(dian)(dian)(dian)(dian)路(lu)中的(de)(de)作用(yong)及原理： 1、原理：电(dian)(dian)(dian)(dian)阻(zu)(zu)器(qi)(qi)由(you)电(dian)(dian)(dian)(dian)阻(zu)(zu)体(ti)、骨架和引出端三部分组成(cheng)（实芯电(dian)(dian)(dian)(dian)阻(zu)(zu)器(qi)(qi)的(de)(de)电(dian)(dian)(dian)(dian)阻(zu)(zu)体(ti)和骨架合(he)二为一） ），并且只有(you)(you)电(dian)(dian)(dian)(dian)阻(zu)(zu)体(ti)决定(ding)电(dian)(dian)(dian)(dian)阻(zu)(zu)值。 。 通常，电(dian)(dian)(dian)(dian)阻(zu)(zu)是(shi)根据欧姆定(ding)律定(ding)义的(de)(de)，在电(dian)(dian)(dian)(dian)阻(zu)(zu)上(shang)加上(shang)恒定(ding)的(de)(de)电(dian)(dian)(dian)(dian)压(ya)会产生多(duo)少电(dian)(dian)(dian)(dian)流(liu)(liu)； 也可以用(yong)焦耳定(ding)律来(lai)定(ding)义，当电(dian)(dian)(dian)(dian)阻(zu)(zu)流(liu)(liu)过(guo)电(dian)(dian)(dian)(dian)流(liu)(liu)时(shi)，单(dan)位时(shi)间内(nei)会产生多(duo)少热量(liang)。 2、限流(liu)(liu)：有(you)(you)时(shi)电(dian)(dian)(dian)(dian)路(lu)中需要一组几(ji)十mA的(de)(de)电(dian)(dian)(dian)(dian)源，但电(dian)(dian)(dian)(dian)路(lu)中其(qi)他地方不使用(yong)其(qi)电(dian)(dian)(dian)(dian)压(ya)。 这时(shi)不适合(he)单(dan)独使用(yong)一组DCDC或(huo)LDO，因为电(dian)(dian)(dian)(dian)流(liu)(liu)太小。 这时(shi)可以采(cai)用(yong)齐纳管(guan)稳压(ya)电(dian)(dian)(dian)(dian)路(lu)。 3、分压(ya)：ADC采(cai)样电(dian)(dian)(dian)(dian)路(lu)、DCDC输出电(dian)(dian)(dian)(dian)压(ya)反(fan)馈、电(dian)(dian)(dian)(dian)平转换等(deng)分压(ya)。可以承(cheng)受(shou)较(jiao)大的(de)(de)电(dian)(dian)(dian)(dian)流(liu)(liu)负载。龙岗区贴片合(he)金电(dian)(dian)(dian)(dian)阻(zu)(zu)
