硕凯电子可提供引线型、薄片型和贴装型PTC自恢复保险丝,电压可从6V到600V
工程师在为客户提供选型建议时,都会先了解客户产品的防护类型,是防雷、过压、过流还是防静电,从而确认选择哪一类电路保护器件;再根据产品的防护等级以及工作电压、工作电流等数据确认最终的产品型号,并打样测试,在测试报告出来,确定所选型号合适,才会将最终结果反馈给客户。这是硕凯电子完整的电路保护器件选型过程,当然在前期的了解中还需要了解客户产品的PCB板大小,根据PCB板空间来确定电路保护器件的封装。为减少更换不便带来的麻烦,过流防护中自恢复保险丝已经成为主力,那么自恢复保险丝的封装有哪些呢?
当线路发生短路或过载时,流经自恢复保险丝的大电流产生的热量使聚合树脂融化,体积迅速增长,形成高阻状态,工作电流迅速减小,从而对电路进行限制和保护。当故障排除后,PTC可恢复保险丝重新冷却结晶,体积收缩,导电粒子重新形成导电通路,自恢复保险丝恢复为低阻状态,从而完成对电路的保护,无须人工更换。市场中常见的自恢复保险丝有引线型、直插型、薄片型和贴片型几种,以下是硕凯电子自恢复保险丝的大概介绍:
规格系列:SCF0603系列、SCF0805系列、SCF1206系列、SCF1210系列、SCF1812系列、SCF2920系列、SC6系列、SC16系列、SC30系列、SC60系列、SC135系列、SC250-P系列、SC250-T系列、SC600系列、JK-P系列
封装形式:引线型、薄片型(带型)和贴装型
封装尺寸:0603,0805,1206,1210,1812,2016,2920
引线型——耐压值(V):06,16,30,60,90,130,250,600
产品电压:6V-600V
产品电流:0.05A-14A
产品特性:体积小,对电流、温度敏感,电压可从6V到600V,且具有自恢复的特性。
产品应用:自恢复保险丝是具有自动恢复功能的过流保护器件,利用能量动态平衡的原理进行工作。PPTC元件广泛应用于计算机及其外部设备、移动电话、电池组、远程通讯和网络装备、变压器、工业控制设备、汽车及其它电子产品中,起到过电流或过温保护作用。

【经验】自恢复保险丝和TVS的结合使用,可防止四种情况造成的损坏
单独使用自恢复保险丝,或者与TVS二极管结合起来使用,都能防止负载电流过大、转换器出现故障、发动机激活时产生的瞬变电压以及汽车电池极性接反导致器件损坏。在选择PPTC自恢复保险丝器件时,必须考虑到最大负载电流、最高环境温度以及进入高阻抗状态所需要的时间。
