【应用】额定电压600V的贴片电流保险丝0461.500ER用在小基站的电源板上，可提供过电流保护

时间： 2022-12-17 来源：世强

技术问答

小基站的电源板上，为了防止因浪涌产生的电流对器件的损坏，需求一款贴片耐浪涌的电流保险丝（current fuse），要求正常工作时的耐受电流0.5A，电压600V，额定的断开的电参数为60 A @600 VAC，封装不限。

据此给客户推荐了LITTELFUSE（力特）的0461系列，此系列的特征为：

表面安装防浪涌Slo-Blo®保险丝；
只符合UL 60950第三版电源交叉要求标准；
允许设计符合Telcordia GR-1089-CORE以及TIA-968-A(原FCC)第68部分)浪涌标准；
提供与Littelfuse SIDACtor®瞬态电压抑制器(TVS)或GreentubeTM气体等离子体避雷器的协调保护，无串联电阻；
设计用于要求范围很广的服务电信和网络设备；
相对于1.25A的保险丝额定参数来说，2A保险丝在2.2A浪涌电流下提高了温升性能；
订购的标准镀银黄铜帽的产品不含卤素以及符合RoHS要求的兼容无铅焊料和更高温度；
UL认证符合UL/CSA/NMX 248-1和UL/CSA/NMX 248 - 14；
符合IEC/EN 60127-1标准及IEC/ en60127 -7。

根据客户实际要求，以及参考规格书的如下料号编码原则，选型的具体型号为0461.500ER：

0461.500ER的主要参数如下：

由上述特征描述和上表可以看出，0461.500ER的参数满足客户要求：额定电压600V，正常工作时耐受0.5A的电流，断路时的电流为60A，能够很好的保护电路板上的器件免受浪涌的伤害。

【应用】表面贴装型特快熔断型保险丝0456030.ER应用于低压高电流直流电源板，有效保护后级电路

随着科技的发展，越来越多的电器、机器出现，而往往新电器的出现也伴随着对电源的新要求，低电压高电流的电源越来越多，这也就需要对电路进行保护，防止过流而损坏后级电路。保险丝就是一种过流保护器件，当电路中电流过大时，保险丝产生热量将自身熔断，导致电路断路，从而达到保护电路的目的。但是现在低电压高电流的保险丝较少，本文就根据一个低电压高电流的直流电源板来推荐力特的456系列保险丝，作为参考。

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。

技术问答发布时间 : 2017-09-26

开关电源中，如何选用保险丝的电流？

一是看电路的最大持续工作电流，二是看工作环境温度，三是所选保险丝的认证情况，比如UL认证的保险丝折减率是75%。保险丝的额定电流=电路最大持续工作电流/（温度折减率*保险丝认证折减率），举个例子，电路的最大持续工作电流为2A，工作温度最大为80℃，对应保险丝的温度折减率为88%，UL认证，2A/（0.88*0.75）=3.03A，则所选保险丝的额定电流应大于3.03A。Littelfuse作为保护器件的大品牌，保险丝种类丰富，认证齐全，可以在平台搜索了解详情，有具体需要可以提选型帮助，保险丝不光只看电流的。

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。

Littelfuse 保险丝 ,规格书中维持电流ihold是什么意思?触发电流itrip是什么意思?请阐述详细电流先后保险丝的工作状况，请教专业

保险丝的Ihold 就是保持电流，也就是工作电流，一般标明的多少A，在该电流下工作，保险丝不会动作。Itrip就是触发电流，熔断电流, 一般为保持电流的两倍，达到该电流，保险丝会快速动作。Ihold和Itrip之间的电流，会引起保险丝发热，如果散热条件差，引起热量累计，也可能导致保险丝动作。Ihold和Itrip的值和温度有关系，温度越高，Ihold越小。
