Date()/36e5)]; </script> </div> </div> </div> <div class="con"> <span style="line-height:200%;"><span style="font-size:16px;"><span style="font-family:微軟雅黑,arial;"><a href="http://www.forsakring-online.com/products/category-19/"><strong><span style="color:#FF0000;">電阻器</span></strong></a>是電子線路中最常見的電子元器件之一。<br /> 電阻器被簡稱為電阻，英文名resistance,通?？s寫為R,。歐姆定律公式，I=U/R,那么R=U/I,電阻的基本單位是歐姆，用希臘字母“Ω”表示，有這樣的定義：導體上加上一伏特電壓時，產生一安培電流所對應的阻值。電阻的主要職能就是阻礙電流流過。<br /> <br /> 電子產品種類繁多，那么電阻的分類有哪些呢，電阻的分類如下圖：</span></span></span><br /> <a href="http://www.forsakring-online.com/products/category-19/"><img src="/u_file/1910/photo/1910/2019101113502090.png" title="電阻器分類圖" /></a><br /> <br /> <span style="line-height:200%;"><span style="font-size:16px;"><span style="font-family:微軟雅黑,arial;">隨著電子產品的更新換代升級，電子元器件的產品也隨之升級，以前大部分都是以插件電阻為主，插件繞線電阻以及插件電阻（炭膜電阻，金屬膜電阻，金屬氧化膜電阻，金屬箔電阻以及玻璃釉膜電阻等），隨著電子產品的低功耗，產品小型化，便攜式以及生產人工成本的變化都要求電阻元器件更新換代，由此電阻器逐漸轉變成貼片型的，貼片型的電阻首先是適合大批量機械化生產以及產品一致性的把控，大大減少了產品的不良率及人工成本，同時給下游產品應用商也帶來了機械化生產節省人工成本和時間成本，以及節省產品占用空間，更加適合產品的小型化，因此，電阻器逐漸被貼片型的快速占據市場，除了部分工業控制類以及LED及電源行業還在繼續沿用插件型電阻以外，其他大部分都被貼片型電阻器所替代。<br /> <br /> 貼片型電阻主要的分類：<br /> 1、普通厚膜貼片電阻：主要是以1%，5%為主，因為成本低廉，在整個市場上占據絕對地位。</span></span></span><br /> <a href="http://www.forsakring-online.com/products/category-75/"><img src="/u_file/1906/photo/8068c1b1ac.png" title="普通厚膜電阻" /></a><br /> <span style="line-height:200%;"><span style="font-size:16px;"><span style="font-family:微軟雅黑,arial;">2、薄膜貼片電阻：主要是以0.1%，0.5%，0.25%，0.01%，0.025%，0.05%，1%精度為主，主要是生產高精度，低溫漂電阻為主，溫漂主要有2ppm,5ppm,10ppm,15ppm,25ppm,50ppm,75ppm為主。其主要應用于各類儀器儀表及檢測設備等需要高穩定性的產品上使用。</span></span></span><br /> <a href="http://www.forsakring-online.com/products/category-76/"><img src="/u_file/1906/photo/eaf5871e8e.png" title="薄膜精密電阻" /></a><br /> <span style="line-height:200%;"><span style="font-size:16px;"><span style="font-family:微軟雅黑,arial;">3、低阻值貼片電阻：主要是以阻值進行劃分，一般低于1R（歐姆/Ω）被稱之為低阻值電阻，起主要作用是進行電流檢測以及電壓檢測為主，廣泛應用于各類電池保護板以及保護電路中。</span></span></span><br /> <a href="http://www.forsakring-online.com/products/category-77/"><img src="/u_file/1906/photo/841646d7e8.jpg" title="低阻值采樣電阻" /></a><br /> <span style="line-height:200%;"><span style="font-size:16px;"><span style="font-family:微軟雅黑,arial;">4、高阻值電阻：同樣是以電阻阻值進行劃分，一般以超過1MR（兆歐/MΩ）以上的都成為高阻值電阻，有更高阻值的單位為G，這類產品應用會比較少，主要是儀器儀表以及部分工業設備等，市場應用較廣的是1M~10M阻值之間，例如：智能手環或智能手表中就會用到0201/0402 3M 1%的電阻，以及部分醫療檢測或者汽車檢測設備就會用到0603 3M 0.1% 50ppm的高精度高阻值電阻等。<br /> 5、高功率電阻：這一類產品是以功率為劃分，體積，阻值，精度不變的情況下，功率要做的更高，是為了更好的過大電流使用，例如：常規1206體積的電阻功率為1/4W，而做為高功率電阻的功率則是1/2W，這類產品主要應用于電源設備以及PLC等電路。<br /> 6、高壓電阻：是以電阻的耐壓值為基準，比如200V,500V,1KV等。<br /> 7、合金電阻：合金電阻主要是以低阻值為主，阻值一般在0.75R以下，但是也有極少的品牌可以最大做到4R，目前合金電阻最小的尺寸可以做到0402，最大的體積可以做到5930（僅限貼片類），功率最大可以做到20W。</span></span></span><br /> <a href="http://www.forsakring-online.com/products/category-74/"><img src="/u_file/1907/photo/b992643901.png" title="合金電阻" /></a><br /> <span style="line-height:200%;"><span style="font-size:16px;"><span style="font-family:微軟雅黑,arial;">8、高頻電阻：因為電阻本身的電感量極小，也被稱之為無感電阻。用于高頻電路，阻值小于lkQ，功率范圍寬，最大可達lOOWo(4)高壓型。用于高壓裝置中的電阻，功率在0.5-15W之間，額定電壓可達35kV以上，標稱陽值可達lGQo(5)高阻型。阻值在10MQ以上，最高可達l014Qo(6)電阻網絡（電阻排）o綜合掩膜、光刻、燒結等工藝技術，在一塊基片上制成多個參數、性能一致的電阻，連接成電阻網絡，也叫集成電阻。<br /> 9、晶圓電阻：具有繞線電阻的特性也有貼片電阻的特性，主要應用于電表，新能源汽車充電設備等市場。<br /> 10、濕敏電阻：濕敏電阻由感濕層、電極、絕緣體組成。氯化鋰濕敏電阻隨濕度上升而電阻減小，缺點為測試范圍小、特性重復性不好、受溫度影響大。碳濕敏電阻缺點為低溫靈敏度低、阻值受溫度影響大，較少使用。氧化物濕敏電阻性能較優越，可長期使用，受溫度影響小，阻值與濕度變化呈線性關系。<br /> 11、壓敏電阻：主要有氧化鋅、碳化硅和氧化鋅壓敏電阻。<br /> 12、熱敏電阻。熱敏電阻的電阻值會隨著本體溫度的變化呈現出階躍性的變化，具有半導體特性。熱敏電阻按照溫度系數的不同分為正溫度系數熱敏電阻（簡稱PTC熱敏電阻）和負溫度系數熱敏電阻（簡稱NTC熱敏電阻）o超過一定的溫度（居里溫度）時，PTC熱敏電阻的電阻值隨著溫度的升高呈階躍性增高。<br /> 13、力敏電阻。力敏電阻是一種阻值隨壓力變化麗變化的電阻，可制成各種力矩計、半導體話筒、壓力傳感器等。主要品種有硅力敏電阻器、硒碲合金力敏電阻器，相對而言，合金力敏電阻器具有更高靈敏度。<br /> 14、光敏電阻。光敏電阻大多是由半導體材料制成的，它利用半導體的光導電特性使電阻器的阻值隨入射光線的強弱發生變化。當入射光線增強時，電阻值明顯減??；當入射光線減弱時，阻值顯著增大占4)氣敏電阻。氣敏電阻利用某些半導體吸收某種氣體后發生氧化還原反應制成，主要成分是金屬氧化物，主要品種有金屬氧化物氣敏電阻、復合氧化物氣敏電阻、陶瓷氣敏電阻等。<br /> <br />
