<p class="vspace"><font color="#000000" size="3">单片陶瓷电容器(通称贴片电容)是目前用量比较大的常用元件,就AVX公司生产的贴片电容来讲有NPO、<span class="wikiword">X7R</span>、<span class="wikiword">Z5U</span>、<span class="wikiword">Y5V</span>等不同的规格,不同的规格有不同的用途。下面我们仅就常用的NPO、<span class="wikiword">X7R</span>、<span class="wikiword">Z5U</span>和<span class="wikiword">Y5V</span>来介绍一下它们的性能和应用以及采购中应注意的订货事项以引起大家的注意。不同的公司对于上述不同性能的电容器可能有不同的命名方法,这里我们引用的是AVX公司的命名方法,其他公司的产品请参照该公司产品手册。<br/>NPO、<span class="wikiword">X7R</span>、<span class="wikiword">Z5U</span>和<span class="wikiword">Y5V</span>的主要区别是它们的填充介质不同。在相同的体积下由于填充介质不同所组成的电容器的容量就不同,随之带来的电容器的介质损耗、容量稳定性等也就不同。所以在使用电容器时应根据电容器在电路中作用不同来选用不同的电容器。 </font></p>
<ul>
<li><font color="#000000" size="3">npo电容器<br/>NPO是一种最常用的具有温度补偿特性的单片陶瓷电容器。它的填充介质是由铷、钐和一些其它稀有氧化物组成的。NPO电容器是电容量和介质损耗最稳定的电容器之一。在温度从-55℃到+125℃时容量变化为0±30ppm/℃,电容量随频率的变化小于± 0.3ΔC。NPO电容的漂移或滞后小于±0.05%,相对大于±2%的薄膜电容来说是可以忽略不计的。其典型的容量相对使用寿命的变化小于±0.1%。 NPO电容器随封装形式不同其电容量和介质损耗随频率变化的特性也不同,大封装尺寸的要比小封装尺寸的频率特性好。下表给出了NPO电容器可选取的容量范围。 </font></li></ul>
