【选型】如何选择汽车水泵中的电解电容
黑金刚Nippon Chemi-Con是电解电容器的顶级制造商,全球市场占有率位列首位,其产品广泛用于汽车电子、工业自动化、新能源设备、通信网络和生活家电等市场。
水泵是汽车水循环散热系统的一部分,其中马达部分的电源平滑电解电容器选型涉及到温度特性、ESR和寿命的要求均比较严格。铝电解电容是最常用的滤波电容,具有容值范围宽、开路失效模式、价格便宜等优势,但普通的铝电解电容无法满足对ESR、温度和纹波特性要求较高的应用。
针对汽车水泵的应用,黑金刚推出了导电性高分子混合型铝电解电容HXC系列,混合电解电容在电解质方面既有液体也有固体电解质,它具有铝电解电容高容量、低漏电流的性能,同时还具有固态电容高纹波电流、低ESR的特性,以下是HXC系列混合铝电解电容参数:
工作电压 | 工作温度 | 纹波电流 | 容值范围 | 能量损失 | ESR | |
HXC | 16V | -55~125 ˚C | 2100mArms | 47-470uF | 0.16 | 18-80mΩ |
25V | -55~125 ˚C | 2000mArms | 33-330uF | 0.14 | 20-80mΩ | |
35V | -55~125 ˚C | 2000mArms | 22-270uF | 0.12 | 20-100mΩ | |
50V | -55~125 ˚C | 1600mArms | 10-120uF | 0.10 | 25-120mΩ | |
63V | -55~125 ˚C | 1400mArms | 6.8-82uF | 0.08 | 30-120mΩ |
汽车水泵长期工作在高温状态下,要求电解电容最高工作温度达到125 ˚C、等效串联电阻ESR尽可能低、具备长期可靠性。黑金刚HXC系列混合电解电容工作温度范围-55~125 ˚C,最低18mΩ的等效串联电阻ESR,使用寿命4000小时;符合AEC-Q200标准。
综上,黑金刚HXC系列混合电解电容可以提供6.8-470uF多种容值可选,贴片封装尺寸5*5.8-10*10mm,16/25/35/50/63V五种额定工作电压,可以满足不同车型的汽车水泵马达电源滤波应用。
