Flexibility of Multilayer Ceramic Capacitors: Guaranteed 5mm of bend on AEC-Q200 certified components

Posted by Peter Matthews on Jun 12, 2024 8:46:17 AM

Today, with the continued drive for more technical features in conventional cars and the increasing electrification of the drive train, the challenges facing electronics designers are ever increasing. Alongside a drive to lower costs and smaller form factors, MLCC’s are being used in ever harsher applications and in ever increasing numbers. This is driving board population density upwards and with it concerns for reliability and particularly the likelihood of mechanical cracking. Thus electronic designers are now demanding flexibility that exceeds the current Automotive Electronic Council bend test specification (AEC-Q200 Rev D June 1, 2010).

Trends in Wind Power Generation

Posted by Peter Matthews on May 22, 2024 8:15:00 AM

In our review of today’s trends in power electronics, we discussed the growth in the renewable energy market and the resulting increased investment in renewable energy technologies, such as wind. As a result, global demand for wind power is surging. To keep pace, not only are there more wind turbines being installed onshore and offshore, but the generation capacity of each turbine is also growing substantially. This is changing the requirements for the power electronics needed for these systems. In this blog, we review some of the key wind power generation trends fueling the ability to provide increased capacity and driving changes in the power electronics required for these systems.

Exploring the Capacitor Technologies Needed in Electric Vehicles

Posted by Peter Matthews on May 8, 2024 8:14:00 AM

The electrical power systems in most modern technologies, like electric vehicles (EVs), are complex. In EVs specifically, power systems are responsible for performing many tasks such as converting AC to DC and DC to AC as well as managing changing power levels in DC/DC conversion. When performing these tasks, manipulating AC voltages and removing noise from DC voltage requires passive components such as capacitors, to perform many “jobs” inside the power system. But no single capacitor type can perform all these jobs since each one has different requirements for voltage, size, temperature, and reliability. Therefore, a variety of capacitor technologies, such as ceramic, film, and aluminum, are required to meet all these needs.

The Influence of Phase in Filters for Radar

Posted by Peter Matthews on Apr 24, 2024 8:30:00 AM

This is the fifth installment in our RF Components for Radar series. In the first installment, we provided an overview of the key functional units in radar, including duplexing, filtering, power amplification, waveform generation, low-noise amplification (LNA), receiving and analog-to-digital conversion (ADC). Since then, we’ve covered duplexing, switch filter banks and filters in detail. In this post, we’ll discuss what phase can tell us about filter performance in radar applications.
