【应用】NCC的KMG系列微型铝电解电容器用于音频电路，有效提升信噪比提高听感
在一次产品展会上，一位行业客户看中了笔者公司的一款中端音视频产品，在后续的产品评测中，客户对产品的外观和相关接口功能都很满意，唯一有欠缺的就是RCA音频输出的音质相对比较平庸，希望能做一些优化，将音质提升上去。据此笔者公司做了相关评估，因为是中端产品，音频DAC以及相关的电容和运放等物料使用的是比较常规的物料，信号质量只能算中等。不过当初进行产品设计的时候，音频RCA输出这块板子单独做了一块小板，通过插座和主板进行连接，因此可以通过单独更换音频小板就能提高音频质量。
现在考虑重新设计RCA音频小板，音频DAC芯片采用高端产品的DAC芯片（AKM方案），周边匹配电路的物料也重新进行选择，包括电源、电容、运放和电阻等。大部分板子上的电容用量比较多，包括普通的电解电容和陶瓷电容；如果成本能接受的话，音频的模拟电路可以考虑使用高端的电解电容和薄膜电容。目前笔者公司高端产品在使用的电解电容是NCC的KMG系列微型铝电解电容，该品牌电容在很多的音频产品上都能看到它的身影，口碑很好；这款改进型产品也是直接沿用了该品牌物料。下图是RCA板子的DAC原理图。

本次升级采用了AKM的DAC芯片，该芯片在市场上的口碑很好，很多中高端产品都有在使用。该芯片是将I2S信号转换成模拟信号，周围配上一些控制电路；在该电路中需要重点考虑模拟电路和数字电路的处理。
图中数字电路的电源电路继续使用陶瓷电容，推荐使用X7R或者NPO材质，而模拟电路的电源电路采用了NCC电解电容（图中的CD1和CD3）配合小容值的陶瓷电容；同时在布局中要考虑数字电路和模拟电路的隔离，最终通过电阻实现单点连接，尽量保证模拟信号的干净度。
NCC的KMG系列是微型铝电解电容器，该系列具有体积小、电压范围宽和容值宽等特点；它的工作温度范围为-55℃到+105℃（6.3V~100Vdc），能满足大多数产品的使用环境。
KMG系列电容主要是用于电源的滤波处理，需要关注它的容量、耐压、漏电流、ESR、纹波电流参数和损耗角正切值参数等。本方案选用的是KMG系列中100uF/35V的产品，耐压值会比较大，主要是考虑到该电容值还要用于运放双电源的电源滤波处理，同时更高的耐压也能提高一些参数的指标，比如降低ESR、降低漏电流、降低损耗角正切值和提高寿命等。
KMG系列容器的漏电流、ESR和损耗角正切值都相对比较小，在音频的工作频带（20Hz~20KHz）内能保持优良的参数指标。该电容是用在音频模拟部分的电源滤波上，较小的ESR和损耗角正切值可以保证电源滤波的纯净度，经过该电容滤波之后的干净电源提供给DAC转换电路，更有助于提高音频的音质。该电容的纹波电流参数同其他同规格电容比更大，更大的纹波电流有助于提高音频的性能，比如低频会更加饱满富有弹性，高频更有延伸性和减少粗糙感。
用于音频方面的电容不仅要关注它的指标参数，还需要关注它配合产品使用的实际听感。前期电容选型的时候，我们也有针对性的找了几家铝电解电容，将他们分别用在不同的黑盒子里面，经过专业人员的仔细试听，大部分人认为使用NCC电解电容的产品，声音听起来底噪会更干净。本次产品升级，我们也是沿用了前期的产品选型，继续使用NCC电解电容器，下图是我们的产品细节图。
图2. 使用NCC电容产品细节图
图中茶褐色的电解电容就是NCC电解电容器，此次产品升级使用新的DAC芯片配上KMG微型铝电解电容器，性能指标经过AP音频分析仪测试，提升明显，信噪比从108dB提升到了115dB，产品的实际听感也得到了客户的认可。
