INTRODUCTION
The 303143 (0.150" lead spacing) and 303143L (0.200"
lead spacing) Bulk Metal
®
Z-Foil resistors represent the 3
rd
in a series of ultra-precision resistors since the first Bulk
Metal Foil resistor was introduced by Vishay in 1962. Each
represents an improvement on the earlier model. The TCR
slope of the 303143 and 303143L is 0.2 ppm/C (- 55 °C to
+ 125 °C, + 25 °C ref.) and is an order of magnitude better
than the original S102C. The Bulk Metal Z-Foil resistor is the
ultimate choice in the most demanding analog applications.
The Z-Foil technology provides a significant reduction of the
resistive component’s sensitivity to ambient temperature
variations (TCR) and applied power changes (PCR).
Designers can now guarantee a high degree of stability and
accuracy in fixed-resistor applications using solutions based
on Vishay’s revolutionary Z-Foil technology.
Our application engineering department is available to
advise and to make recommendations.

Differential Data Transmission: What's the Difference?
隔离器的主要功能是通过电气隔离栅传送某种形式的信息,同时阻止电流。隔离器采用绝缘材料制造,可以阻止电流,隔离栅两端都有耦合元件。信息通常在传输通过隔离栅之前由耦合元件编码。在单端数据传输中,我们使用变压器,初级绕组的一端接地。输入信号中的逻辑转换编码为脉冲,相对于地面始终为正极性,位于发送器芯片上。这也称为“一脉冲两脉冲”,因为上升沿编码为两个连续脉冲,而下降沿表示为单个脉冲(请参见图1顶部)。隔...
