Addressing Differential and Common Mode Noise With Innovative Dual-Mode Choke Technology

CMF Series Dual Mode Chokes

Circuit designers must deal with many types of noise: internal, external, RF, line frequency and more. Noise can be a limiting factor in system performance and so must be addressed and minimized. The question is “at what cost and effort?”  Is it better to sacrifice performance or cost?  In either

Supercapacitors Come Of Age

Figure 1. Power comparison of Murata’s supercapacitors with various battery technologies

Within just a few years, devices that previously housed no electronics – let alone information processing capabilities – have become increasingly ‘smart’, joining the Internet of Things. To fully realisethe benefits of IoT, intelligent device performance levels and functionality have increased exponentially. Increased

Power Protection Starts with Switches
Electricity is the crux of modern society. Without it we couldn't power our factories, charge our gadgets, keep our medical equipment running or even keep food from spoiling. From lighting, communication, heating, cooling, motor control, and more, the fact of the matter is our world runs on electricity. While

Resistor Specifications And How To Interpret Them

Figure 1. Power/voltage vs. resistance value

Resistors are one of the simplest electronic components. However, the specifications typically shown on datasheets can be confusing, and are often misinterpreted. In this article we discuss the different performance characteristics, the test conditions, and how to interpret the test results. We discuss potential

Implementing Tapped Buck Topology

Figure 1. Tapped Buck Schematic

When designing a medium power (10 W – 20 W), non-isolated, AC-DC power supply the choice is typically between a conventional buck topology and a more complex, flyback transformer based circuit. The buck converter design, although simple and easy to design with, has some drawbacks. Buck converters

Functionality Convergence in IIoT

Figure 1: Example of Arm’s TrustZone technology demonstrating compartmentalization.

Today’s Industrial Internet of Things (IIoT) is rapidly changing how connected devices are enabled in modern heterogeneous multicore system-on-chip (SoC) architectures. These multicore environments reduce operational and maintenance costs by converging what were previously multiple discrete functions on a

In our electrified world, we have become accustomed to continuity. If an airline scheduling system goes down due to a power outage or our electric vehicle runs out of charge unexpectedly, we’re outraged. Battery systems providing backup and motive power should have guaranteed availability; but how is this

Current datacenters typically have a 12V backplane and distribution on board and need to convert the voltage down to around 1V, which is usually achieved with a synchronous buck regulator, single- or multi-phase. The racks in these datacenters normally max out at a power rating of 20kW. There is a need in the
