【器件】国产车规快熔保险丝QF1206G3A00T用于智能车载监控终端,分断电流能力达50A@65Vdc
为避免智能车载监控终端电源输入因负载短路异常造成燃烧或爆炸风险,一般需要在电源输入加一款快熔保险丝做过流防护设计,选型因素参考如下:
1、 额定工作电压:平台化设计,兼容车载12VDC或24VDC供电,以2倍过压考量,一般选择耐压至少48VDC保险丝设计更安全;
2、 额定工作电流:与负载功率大小相关,一般电源输入电流2A左右,以1.5倍过流考量,选择3A的保险丝设计即可;
3、 小尺寸贴片保险丝
4、 通过AEC-Q200
针对如上的设计需求,推荐AEM科技快熔保险丝QF1206G3A00T,最大额定工作电压65VDC,在环境温度25℃条件下,额定工作电流3A,分断电流能力达50A@65Vdc,通过AEC-Q200认证,典型电性参数参考如下图1所示。
图1:AEM科技快熔保险丝QF1206G3A00T典型电性参数
推荐理由如下:
1、 分断电流能力达50A@65Vdc,采用熔丝内置式设计,避免熔断时能量外泄,产品可靠性高;
2、 采用1206表贴封装,满足小型化设计需求;
3、 耐高温:宽工作温度范围-55℃~150℃,具有出色的耐高低温工作能力;
4、 符合AEC-Q200测试标准,经过高温、震动等多项严格的可靠性测试;
