【选型】力特快熔陶瓷保险丝用于车灯控制板电源输入过流防护设计,小尺寸,分断电流能力达50A
为避免车灯控制板12V电源输入因负载短路异常造成后级IC芯片烧毁风险,建议在电源输入加一款特快熔保险丝做次级过流防护,选型因素参考如下:
1、 额定工作电压:乘用车12V蓄电池供电,以2倍过压考量,一般选择耐压至少24VDC险丝即可
2、 额定工作电流:与负载功率相关,一般输入电流1.6A左右,以1.5倍过流防护,建议选择2.5的保险丝设计即可
3、 小尺寸
针对如上的设计需求,推荐LITTELFUSE(力特)特快熔陶瓷保险丝045302.5MR,2410封装,最大额定工作电压125VAC/VDC,额定工作电流2.5A,分断电流能力达50A@125VAC/VDC,工作温度范围-55℃~125℃,通过UL、CSA、PSE、CE、TUV等安规认证,典型电性参数参考如下图1所示。
图1:Littelfuse(力特)特快熔保险丝045302.5MR典型电性参数
推荐理由如下:
1、 分断电流能力50A,具有高的安全切断电流能力,产品可靠性高;
2、 采用2410封装,典型尺寸仅6.1*2.69mm,占板空间少,满足小型化设计需求;
3、 通过UL、CSA、PSE、CE、TUV等安规认证,可满足欧美日等出口安规认证要求。
