OVERVIEW Toroidal transformers only produce minimal leakage fields thanks to their shape. This means that the surrounding components remain free from interference. The transformers feature a very low design height and offer a crucial advantage as power, safety or isolating transformers in difficult installation conditions. PTC Series toroidal transformers can be soldered directly onto a PCB ...

今天主要给大家介绍一种电子元器件——PTC元件。本文主要从PTC效应、什么是PTC器件、PTC器件的关键电参数和PTC的实际应用场景进行展开说明。 PTC效应PTC (Positive Temperature Coefficient) 效应 , 即正温度系数…
过流过载保护 PTC热敏电阻器 选用指南 1.最大工作电压 PTC热敏电阻器串联在电路中,正常工作时仅有一小部分电压保持在PTC热敏电阻器上,当PTC热敏电阻器启动呈高阻态时,必须承受几乎全部的电源电压,因此选择PTC热敏电阻器时,要有足够高的最大工作电压,同时还要考虑到电源电压可能产生的 ...
PTC热敏电阻的I-V特性如图4所示。 施加电压使得电阻的内部发热和向外的散热达到平衡状态时,外加电压和稳定自电流之间关系建立。定值电阻区域内、V = IR关系成立,PTC热敏电阻无自发热。PTC热敏电阻还拥有最大电流点和恒功率区域两个参数。
使用线性近似方法下的传感器电路精度 之所以选择 TMP61 线性热敏电阻, 是因为它在整个温度范围内具有电阻响应。要求解电阻网络,假定 TMP61 在整个温度范围内的电阻响应完全是线性的。误差与分压器输出电压 VPTC(T)( 与温度成函数关系)的轻微非线性行为有关。
