小设计大产品(沈涛).pdf

知道我们在哪里—设计的流程 •带着枷锁跳舞—设计的原则 •没有规矩不成方圆—设计的规范 •度—设计的矛与盾 •它看起来很有型—情感化设计 •设计的责任

TLP291(GB-TP,SE(T_2015-08-11.PDF

TLP291 consists of photo transistor, optically coupled to a gallium arsenide infrared emitting diode. TLP291 is housed in the SO4 package, very small and thin coupler. Since TLP291 is guaranteed wide operating temperature (Ta=-55 to 110 ˚C) and high isolation voltage (3750Vrms), it’s suitable for high-density surface mounting applications such as small switching power supplies and programmable controllers
