【选型】采用PICO®技术的SMF保险丝,是电信网络设备电路保护的最佳解决方案!
力特(LITTELFUSE)是全球领先的电路保护产品供应商,产品涉及到电路保护器件的方方面面,其中包括太阳能应用电路保护、保险丝、气体放电管、LED保护器、保护继电器、开关型晶闸管等。力特(Littelfuse)目前推出了2个系列贴片封装的PICO® SMF保险丝。其中包括459系列特快熔断型SMF保险丝和460系列Slo-Blo® SMF保险丝。
459系列和460系列保险丝可以应用在无线基站、网络设备和电信设备等领域。均符合RoHS标准,且无铅,无卤素。459系列的熔断时间较460系列保险丝熔断时间短。两个系列的保险丝均采用了Littelfuse PICO®保险丝技术,并且两个系列的保险丝的工作温度相同,工作温度范围是-55℃-125℃。
459系列
459系列特快熔断型SMF保险丝采用Littelfuse PICO®保险丝技术,并且提供了表面贴装封装。该系列产品符合RoHS标准。在300%电流等级的时候最大熔断时间为0.1s,459系列保险丝的额定电流范围0.062-5A,其最大额定电压为125V,在最大额定电压下的中断额定电流值为50-300A,其具体明细如图一所示。其主要优势是:
•熔断速度快
•宽电流额定范围:62mA至5A
•宽工作温度范围
•低温重新评估
•符合RoHS标准
图一 459系列保险丝具体参数明细
460系列
460系列Slo-Blo® SMF保险丝采用Littelfuse PICO®保险丝通孔技术,并且提供了表面贴装封装。该系列产品符合RoHS标准。在300%电流等级的时候最大熔断时间为3s,最小熔断时间为0.2s,460系列保险丝的额定电流范围0.375-5A,其最大额定电压为125V,在最大额定电压下的中断额定电流值为50A,其具体明细如图二所示。其主要优势是:
•极高浪涌电流承受能力
•宽电流额定范围:0.375A至5A
•宽工作温度范围
•无卤素、符合RoHS标准

如何选择保险丝的额定电流参数?
根据电路的额定工作电流来选择保险丝的额定电流即额定电流=工作电流/0.75。当计算出的值不是规格书中常见的额定电流时,应选择最临近额定值的较高值。

如何选择保险丝的额定电流参数?
根据电路的额定工作电流来选择保险丝的额定电流即额定电流=工作电流/0.75。当计算出的值不是规格书中常见的额定电流时,应选择最临近额定值的较高值。

想选择一款贴片式(SMD)自恢复保险丝(PTC),要求保持电流0.2A,跳闸电流0.4A,最大容忍电压30Vdc,最大容忍电流10A,请问是否有合适型号推荐?
推荐1210L020WR自恢复保险丝,尺寸为0.12 inch x 0.10 inch(3mm x 0.1 mm),保持电流0.2A,跳闸电流0.4A,最大容忍电压30Vdc,最大容忍电流10A,可满足设计需求。

在保险丝选型中,额定电压的选择有什么标准?
保险丝的额定电压是指它的公称额定电压,通常就是保险丝断开后能够承受的最大电压值。保险丝通电时两端所承受的电压值小于其额定电压,因此额定电压基本上无关紧要,只需选择额定电压值等于或大于电路电压即可。
