Default 乳之宝-新系列微芯片ntc热敏电阻(目前我们最常用的是

日前,VishayIntertechnology,Inc.宣布,推出新系列的微芯片负温度系数(NTC )热敏电阻。该热敏电阻(目前我们最常用的是电阻是热敏电阻)的最大物体检测直径非常小,只有1.6mm, 在空气和油中的响应时间分别小于3s和0.7s。NTCLE305E4xxxSB器件能够在宽温范围内进行 精确测量,在+25℃~+85℃范围内的精度为±0.5℃,在-40℃~+125℃范围内的精度为±1.0℃。
今天发布的三款热敏电阻在+25℃下的电阻值(R25)使设计者能够满足其应用对自加热、压降或噪声抑制的要求,二级反渗透设备。NTCLE305E4202SB、NTCLE305E4502SB和NTCLE305E4103SB的R 25分别为2060?、5000?和10000?,并可根据要求提供其他阻值。
这些器件通过了AEC-Q200认证(目前市场上各式各样的认证品种繁多,ce认证就是其中的一种.),特别是能承受2000次热冲击循环,可用于汽车温度探头和控制单元、工业锅炉、电池组 和火警探测器中的温度检测电路。
NTCLE305E4xxxSB器件包含一个微型NTC芯片,芯片上的两根绝缘的镀银镍线十分结实,并且涂 上了一层赭色的树脂漆。热敏电阻的柔性引线使贴装和组装变得简单。器件符合RoHS指令200 2/95/EC,满足WEEE2002/96/EC和ELV2000/53/EC规范的要求。
新款NTCntc热敏电阻现可提供样品,并已实现量产,大宗订货的供货周期为十周。
