联合式电路保护防止损坏DVB网络设备

Combined Circuit Protection Helps to Prevent DVB Network Devices from Damaging

本文介绍了PolySwitchPPTC器件和RaychemSiBarTSPD器件在设计联合式保护方案时所起到的作用。PPTC器件的可复位功能、较小的体积和低阻值的特性使其很适合过电流保护的设计应用。TSPD的主要优势在于其小巧的体积、导通状态下较低的功率耗散以及精确的"转折"电压。

PolySwitch PPTC and Raychem SiBar TSPD can play an important role while designing combined circuit protection solution. PPTC device has smaller volume, lower resistance and the reset function. These characteristics make it so suitable to be used for overcurrent protection. The main superiorities of TSPD device are small volume, lower power dissipation and precise transition voltage.
