【选型】TE5延时保险丝用于微型逆变器DC/AC电源输出过流防护设计，可直接软焊或插入满足小型化设计需求

时间： 2021-10-29 来源：世强

技术问答

微型逆变器功率一般几百瓦，其DC/AC电源输出电压一般是220VAC~240VAC, 50Hz/60Hz，输出电流一般是1.1A~3.3A ，为避免微逆电源输出因负载短路异常造成燃烧风险，建议在DC/AC电源输出母线上加入延时熔断保险丝做过流保护设计，市面上一般选用250VAC，5A延时熔断保险丝设计。

针对如上的设计需求，推荐选择LITTELFUSE（力特）TE5延时熔断保险丝 39215000000，最大额定工作电压250VAC，额定工作电流5A，分断电流能力达50A@250Vac，工作温度范围-40℃~125℃，实物图及典型电性参数参考如下图1所示。

图1：Littelfuse（力特）保险丝 39215000000实物图及典型电性参数

推荐理由如下：

1、可直接软焊或插入，降低对PCB板的空间要求，满足小型化设计；

2、常温25℃条件下的正常冷却阻值为0.0101Ω，自损耗很小；

3、通过多种安规认证，VDE、UR、CCC、IC、CE，满足国内，国外出口需求；

4、市面上有成熟的应用，产品性能得到验证；

方形保险丝管有何优点？相比之下体积比较小，还有其他优点吗？方形保险丝管如果出现过电流，管子导通会烧断？如果烧断，那这时候更换感觉比管状保险丝管麻烦些，请专家给予指导！

世强电商平台上有供应littelfuse（力特）的TE5方形保险丝，实物图如下littelfuse（力特）的TE5方形保险丝涉及的产品系列及相关电性参数参考如下图示：1、方形保险丝优点：体积小，脚间距5.08mm，占用的线路板空间相对较小。方性保险丝除开两个引线以外，表面全是塑料材料制作而成，所以表面绝缘，具有阻燃和绝缘的作用。具有高分段能力，其中littelfuse 804 系列 - TE UMF延时超小型保险丝分断能力达250VAC/150A。2、仍以littelfuse 804 系列 - TE UMF延时超小型保险丝为例说明，其过流电性参数如下图示：如果方形保险丝出现过流时，需要满足如上电性参数条件方可熔断，如200%过流时，最大120s保险丝熔断。如果保险丝出现熔断失效，是必须要更换的，因为是双引线型焊接封装，更换相对比较麻烦的，这个是没办法避免的。
