【应用】贴片保险丝SF303成功应用于PD充电器的过流保护上,表面贴装2410封装,公制尺寸6.1x2.5MM
PD充电器是带有PD协议的电源适配器,相对传统充电器,其使用了氮化镓MOS。由于氮化镓MOS具有较好的散热性能、较高的击穿电场和较高的饱和速度,使得它能够匹配体积更小的变压器和功率电感,使得同功率的情况下,比传统的充电器体积要缩小1/2到3/4。
由于整个充电器的体积的要求大大减小,除了要求变压器、控制IC、功率电感等主要功能元件小型化、贴片化,还要求安规电容、保险丝等保护器件也要小型化、贴片化,这样才能缩小整体充电器的体积。
如传统充电器在空间尺寸上没有体积要求,一般在交流AC输入端都串联方型插件的保险丝,来满足过流、短路保护的安规要求,但PD充电器由于体积要求的限制,在保险丝选择方面,工程师们一般都倾向于选择贴片系列的保险丝,如电安的SF303系列,它是2410封装,公制尺寸6.1x2.5MM,串在AC输入端,其焊盘间距尺寸正好能满足安规爬电距离的要求。
如下是贴片保险丝SF303在PD充电器中的大概位置:
电安推出小型贴片2410封装小电流、耐压250AC的保险丝SF303系列,它广泛应用于载波模块、LED驱动电源、智能插座、消费类充电器等场合。其外形如下图:
其特点如下:
1、电流0.08-7A可选
2、电压250VAC,慢断,分断能力50A
3、表面贴装2410封装,已经通过UL认证,认证号为E500586
4、宽工作温度范围-55℃ ~ +125℃
5、RoHS环保,无卤素、镀银镀金端子可选

【元件】电安科技推出SF525系列5x20mm贴片保险丝,最高耐压高达500V
随着工业化进程的加快,人们对产品小型化也提出了新的要求。这对小型产品的排板要求很具挑战性。为此,电安科技针对客户这一特殊应用要求,推出了5x20mm贴片方型陶瓷保险丝,在长度上有较大的缩小。贴片的封装在加工上也比插件封装更高效。

电安科技中低压大电流方型贴片保险丝SF335A040应用于化成柜短路保护,最高电压84VDC,分断能力为1500A
华中某化成柜设备客户。有个项目的DC/DC模块上,输入电压85VDC,输出电压5VDC左右,需要在输出端到电池间,串联保险丝,以防止化成中电池异常短路。板子空间的限制,只能选贴片封装的保险丝,设计电流45A左右,考虑到成本、余量及温升等情况,最终给客户推荐了2颗40A并联。
