【选型】用于主板领域的东佳铝电解电容产品选型指导
铝电解电容器与其他的电容相比,具有体型小、容量大、对抗过高电压和逆向电压能力强的特征。在要求高性能和高信赖度的计算机主板、 变频器回路、照相回路中得到广泛应用。
与众多普通的电容品牌相比,KOSHIN东佳电子的KOSHIN铝电解电容和KOAS高分子导电性电容(固态电容)具有更低的阻抗和更高的纹波,同时使用寿命也较更长,在可靠性及稳定性方面也有保证。其生产的铝质电解电容品种繁多,用途广泛,本文整理了KOSHIN东佳铝电解电容在主板领域的产品选型表。
一、DC-DC(电压调节主板)回路
在DC-DC电路中,电容有三种用途,一是振荡,二是储能,三是滤波。据不完全统计,约34%的电子系统故障都是由电源系统的失效引起的。而DC/DC变换器的健康状况主要由输出端滤波铝电解电容决定。针对这部分,东佳有6个系列可供选择,分别是KS/KU/KP/KL/VR/VT,具体区别和参数可见下图。
二、POL (主板的非隔离负载点)回路
随着处理器内核电压降至1V以下,其电流消耗则不断上升,未来的负载点电源(POL)要求有更高的效率、更高的功率密度和更快的瞬态响应速度。从主电路角度考虑,影响瞬态响应性能的主要相关因素,包括输出电感值、负载电流切换时刻、控制器的性能和输出电容。针对这个部分,东佳推荐使用KS/KU/KP/KL四个系列。

【经验】关于纹波电流以及铝电解电容纹波电流如何计算?
铝电解电容的在实际应用中的一个重要参数是纹波电流,此电流关系到电解电容的带载温升,在电容寿命计算时候,在不测量电解电容中心点温度的情况下,可以通过此纹波电流来估计电容的设计寿命,铝电解电容常被用在整流模块后以平稳电压。
