【选型】电冰箱显示屏12V供电端口过流防护设计推荐可恢复保险丝SCF050-24-1206R，待机功耗小于0.2W
为避免电冰箱显示屏12V供电输入因后级短路异常出现可燃风险，建议在电源输入母线上加入可恢复保险丝做过流保护设计，此可恢复保险丝选型因素参考如下：
1、额定电压考量：12V电源输入，以1.5倍过压考量，建议选择耐压为18V以上保险丝；
2、额定电流考量：这个主要与负载相关，一般情况下，额定输入电流为0.5A，选择保护时的动作电流小于2A，选择保持电流为0.5A、动作电流为1A保险丝即可；
3、低待机功耗：建议小于0.2W
4、小尺寸封装
5、低成本
针对如上的设计需求，推荐选择硕凯电子（Socay）的可恢复保险丝SCF050-24-1206R，最大额定电压为24VDC，保持电流为0.5A，动作电流1A，工作温度范围-40℃~85℃，典型电性参数参考如下图1所示。
图1：硕凯电子（Socay）可恢复保险丝SCF050-24-1206R典型电性参数
推荐硕凯电子（Socay）保险丝SCF050-24-1206R理由如下：
1、高耐压：最大额定工作电压为24V，可满足2倍过压的设计要求，更高的设计裕量，提升产品的高可靠性；
2、满足小型化设计：采用1206表面贴装设计，最大封装尺寸仅3.5mm x 1.8mm，可满足小型化设计需求；
3、低待机功耗：可以通过计算得出，利用P=Ihold*Ihold*R得出，，其中Ihod、Rmin和Rmax可通过图1中电性参数表格获取，Ihold=0.5A，Rmin=0.15Ω，Rmax=0.75Ω，带入公式得到Pmin=0.5*0.5*0.15=0.0375（W），Pmax=0.5*0.5*0.75=0.1875（W），即待机状态时的功耗为0.0375W~0.1875W，满足低待机功耗设计需求；
4、世强平台常备库存，具有良好的供货交期，可以快速支持样品和量产服务；
5、硕凯电子作为国产保护器件品牌，具有更低的成本优势。
