Passive Component Advancements for SPE Connectors and Circuit Protection Devices

Passive Component Advancements for SPE Connectors and Circuit Protection Devices Written By: Daniel West | Julian Wilson Abstract: As Single Pair Ethernet (SPE) begins to roll out there will be a need for easy to implement, yet reliable wire-to-board interconnects. Purchasing finished cable and connector assemblies is not always economical or viable. However, it is also undesirable to work with time consuming and difficult to process connectors. Insulation Displacement Connectors (IDC) and Press-Fit technology (images below) require no crimping or soldering processes, and is easily converted to a streamlined process, while maintaining the versatility of cable lengths and positioning. In addition to reliable retention forces and gas tight seals afforded by the cold weld mechanism of IDC, signal integrity is

Advantages of Varistors and Their Applications in the Automotive Field

Advantages of Varistors and Their Applications in the Automotive Field Written By: George Zhang Abstract: Multilayer chip varistors (MLVs) are resistive elements comprising zinc oxide (Zn0) as the main component. In recent decades, they are being used for protection against surge voltage, noise, and transient voltages. Unlike conventional varistors, the maximum peak current and non-linear coefficients are large, and the resistance is very high below a threshold voltage, hardly allowing current to flow. However, when the voltage exceeds the threshold, the resistance drops abruptly and allows a large current to flow. Such properties make MLVs ideal as protective elements in a host of electrical and electronic applications, including automobiles

The Frequency Response Effects of Internal Component Configuration on Multiple Ceramic Dielectric System

The Frequency Response Effects of Internal Component Configuration on Multiple Ceramic Dielectric System Written By: S. Pala | R. Demcko | M. Berolini Abstract: The purpose of this paper is to discuss the frequency response effects of internal designs within ceramic systems. Those effects will be related to component performance parameters for devices used to suppress ESD and control EMI in high speed data lines, which are prone to be damaged by ESD. As communication speed increase, systems become more complicated and performance standards tighten, options to improve EMI/RFI performance becomes of great importance. Long term EMI performance and reliability are of particular importance in automotive, medical and aviation application sectors. A performance comparison will be made between single element
