在电子元器件市场中,电容产品可以说是鱼龙混杂。ameya360电子元器件相信很多消费者在购买贴片电容产品时经常会遇到假冒伪劣、以次充好等一系列问题。因此,ameya360电子元器件认为每个人都必须掌握鉴别真伪贴片电容的能力。ameya360电子元器件在这里和大家简单聊聊怎么区分优质贴片电容和劣质贴片电容。

优质贴片电容和劣质贴片电容的区别

贴片电容外观区别及影响:

优质贴片电容:

1.产品具有很高的尺寸精度,提高了自动化安装的效率和焊锡。

2.产品两侧的端子不易被氧化,颜色为正,可焊锡良品率。

劣质贴片电容:

1.产品尺寸不精确,在自动安装过程中通常会导致焊点出现错位,从而导致焊接不准确,并增加缺陷率。

2.产品两侧的端子容易氧化并变黑,影响焊锡效率。

劣质贴片电容在外观和安装上与优质贴片电容有很大的不同之外,在使用过程中也同样存在许多问题,例如:

1.内部结构差或烧制工艺不成熟会导致贴片电容的结构不稳定,而且很容易断裂。

2.为了降低成本减少工艺造成的容量偏低。

3.不合格的参数和会在使用过程中造成高损耗,并缩短贴片电容的使用寿命。

4.贴片电容的电介质材料差会造成IR值小,容易出现漏电情况。

5.由于耐压性不足,因此将低压贴片电容用作高压贴片电容。在使用过程中容易击穿和烧毁,大大提高了产品的返修率。

贴片电容可以使用长达40年,并且电容值检测基本上在标准误差范围内。IR值由绝缘电子探测器识别,以识别真伪,正常使用的贴片电容其耐压值要达到额定电压的2.5倍才可以。

以上就是ameya360为您介绍的优质贴片电容和劣质贴片电容的区别,是不是能够区分高品质的贴片电容和劣质贴片电容呢?如果还是有疑问,可以直接找ameya360电子元器件。
