Compact High Reliability Chip Varistors for Automotive Applications
TDK Corporation announced the expansion of its lineup of chip varistors for automotive applications. The AVRH series offers a maximum operating voltage of 19 V to 70 V and a capacitance ranging from 4.7 to 50 pF. The miniature voltage protection device is available in IEC case 1005 (EIA 0402) with compact dimensions of just 1.0 mm x 0.5 mm x 0.5 mm. The high reliability AVRH … [Read more...]
Determining Semi-Anechoic Chamber Resonance as a Source of Radiated Emission Measurement Variation Between Chambers and Comparing to OATS Measurements
INTRODUCTION This article describes the lack of an acceptable correlation between anechoic chamber and open field test site radiated emission measurements, which were described in reference 1 in 2000, as well as a lack of correlation between chambers. It was found that emission measurements, which were over the limits in one facility, would pass in another. The lack of a … [Read more...]
EMC Radiated Emission Measurements at 1/3/5/10/30 Meters
INTRODUCTION There are two principal types of emission measurements in the world of electromagnetic compatibility, conducted emission and radiated emission. The conducted emission measurements are either a voltage-capacitive tap type of measurement (typically on a power line) or they are a current-clamp type of measurement (typically on a signal line). Radiated emission … [Read more...]
Resilience is Key to the Connected and Autonomous Revolution
INTRODUCTION Connected and autonomous vehicles have long been hailed as the answer to safe transport. Around 1.25 million people die in road traffic accidents worldwide each year according to E&T– and driver error accounts for over 90 per cent of those deaths[1]. In theory, the removal of the driver as the lead decision maker for vehicle control should reduce this number, … [Read more...]
Chip Fuse Protects Against Overcurrent and Excessive Ambient Temperatures
SCHURTER’s USN 1206 is designed to meet the ever-increasing challenges associated with packing density in power electronics. The new chip fuse offers temperature-sensitivity suitable for both overcurrent protection and protection against excessive ambient temperatures. The USN 1206 is not a pure thermal fuse, per se. It requires a current flow to blow, thus providing … [Read more...]
New RF Connector with Built-in Locking Feature Doesn’t Disengage from PCB
Designers concerned about RF connectors that disengage from the PCB on high shock and vibration applications can rely on a new connector with a built-in locking feature. The new MHF brand I LK Micro RF Coaxial Connector and Wire Harness from I-PEX is designed with a built-in lock that keeps the connector in place on the PCB. Designers no longer have to adhere their RF … [Read more...]
New Heat Shrinkable Tubing Technology Introduced
Zeus PTFE/FEP Dual-Shrink® tubing is constructed with an exterior of heat shrinkable PTFE and an inner layer of FEP. The PTFE outer layer shrinks tightly over inserted parts while the FEP melts and flows into a solid or near-solid encapsulation. The fit is so tight it can withstand the most severe stresses involving pull or vibration. Dual-Shrink® tubing is designed to provide … [Read more...]
