【选型】力特自恢复保险丝598204-000用于智能咖啡机,待机功耗低至0.096W,满足欧美安规出口要求
为避免商用智能咖啡机电源输入因负载短路异常造成燃烧风险,一般需要在230VAC高压电阻过流保护装置加一颗高压自恢复保险丝做过流保护设计,选型因素参考如下:
1、额定工作电压:最高230VAC高压输入,建议选择耐压240VAC自恢复保险丝即可;
2、额定工作电流:与高压电阻阻值大小选型相关,一般允许通过电流约260mA左右,以1.5倍过流,选择保持电流400mA自恢复保险丝设计;
3、低待机功耗
针对如上的设计需求,推荐选择LITTELFUSE(力特)插件自恢复保险丝LVR040K,最大可持续的额定工作电压240Vac,短时的额定工作电压达265Vac,常温20℃下保持电流0.4A,可承受最大故障电流5.5A,工作温度范围-40℃~85℃,典型电性参数参考如下图1所示。
图1:Littelfuse(力特)自恢复保险丝598204-000典型电性参数
推荐理由如下:
1、低待机功耗:可以通过计算得出,利用P=Ihold*Ihold*R得出,其中自恢复保险丝保持电流Ihold为0.4A,Rmin=0.6Ω,Rmax=1.9Ω,其中Ihold、Rmin和Rmax可通过图1中电性参数表格获取,带入公式得到Pmin=0.096(W),Pmax=0.304(W),即待机状态时的功耗为0.096W~0.304W;
2、通过UL、CSA、TUV、CQC等安规认证,满足欧美安规出口要求;
3、市面上有成熟应用,产品性能得到验证;

自恢复保险丝(PTC)的ITRIP电流的意义是什么?
Itrip可以叫做跳变电流,就是指电流超过该值时,电阻会出现大幅增加。其作为自恢复保险丝特有的重要参数,在设计选型时要格外重视。
在伺服驱动器的预充电电路中,采用可控硅做软起动控制,其驱动采用变压器驱动,由于在实测时发现变压器存在磁芯饱和而电流短路的情况,所以希望能找一款过流保护器件?
可控硅驱动采用变压器驱动,脉冲变压器如果磁芯饱和就会有电流短路的情况,推荐采用littelfuse的自恢复保险丝PTC,型号0805L050WR和 0603L020YR,响应时间0.1ms,可以实现可靠地保护。

应用注:设计可靠使用适当电路保护的无人机
描述- 本文探讨了设计可靠无人机时电路保护的重要性。文章指出,无人机事故多由“飞行员失去控制”引起,但实际原因是无人机依赖的子系统(如GPS、接收天线、WiFi I/O端口和电子速度控制器)出现问题。文章强调,所有无人机都易受故障影响,需要实施被动电池安全系统、静电放电(ESD)保护和电机过载保护。文章详细介绍了电池、GPS、接收天线和I/O端口的电路保护方法,包括使用MHP-TA、PolySwitch PPTC、表面贴装熔断器和ESD抑制器等。
【选型】自恢复保险丝1812L110/33MR用于工业级3D视觉相机电源输入过流防护设计,待机状态功耗仅0.0726W
为避免工业级3D视觉相机电源输入因负载短路异常造成燃烧风险,一般在电源输入加一颗自恢复保险丝做过流保护设计,推荐选择Littelfuse(力特)自恢复保险丝1812L110/33MR ,1812封装,最大额定工作电压33VDC,常温25℃下保持电流1.1A,在50℃条件下保持电流830mA,可承受最大故障电流20A。
如何为汽车电动车窗控制开关选择一款汽车级自恢复保险丝实现瞬时过载电流保护?
汽车电动车窗的控制开关接触瞬间会有很大的瞬时峰值电流,约300mA~500mA,持续时间约50ms以内,仅靠电阻无法做到快速响应保护,故设计电路需要再加一级保护,在电源线上串接一颗额定电压30VDC、保持电流Ihold为0.1A,跳闸电流Istrip为0.25A的littelfuse可恢复保险丝microASMD010F,实现瞬时过载电流保护,让控制系统实现高可靠性。
