Because of fast assembling and small sizes, designers are turning to surfance mount technology on their PCBs. Although there are still through-hole (THT) components that need to be soldered by Wave, Through-Hole Reflow (THR), allows designers to solder the Through-Hole Components together with the surfance mount parts in the Reflow Oven, thus canceling the whole Wave Soldering Process; saving time...

In our last episode, we talked about an adapter stick for the RS-485 Standard that was designed to include a complete filter circuit for selected applications. Today's podcast is part two of understanding the RS-485 Transmission Standard, and how to design the correct PCB, measurement of the S-parameters, and an evaluation.

By filtering directly at the interface, interference emissions, electrostatic discharges and fast transients bursts are prevented from entering the system; thus negatively influencing the operating performance. To verify the EMC properties of electrical systems, special tests are carried out in accredited EMC test laboratories, and if these tests are not passed, the application has to be revised....

The most common means of solving electromagnetic noise problems is to shield the system with conductive materials, however, a large number of electronic devices have many parts that operate at high frequencies that can cause complex EMI problems that cannot be removed with conductive shielding. In today's podcast, we discuss ways to avoid these issues by using Flexible Absorber Sheets to supress u...

Besides the basic guidelines for applications, designers need to consider mechanical and electrical properties when selecting FPC connectors and FFC cable. This podcast comes from a recent webinar, in which Wurth Elektronik Application Engineer Frank Fraeber discusses the characteristics and differences of each connector and explains how to select a suitable component for different applications. C...

At the Applied Power and Electronics Conference (APEC) in Houston, Texas in 2022, Wurth Elektronik showcased its Hortirack. The Hortirack is a horticulture grow chamber that allows users to grow plants and produce from seedlings; using an array of horticulture LEDs produced by Wurth Elektronik. Today's podcast gives insights into the world of horticulture LEDs and how they can support food product...

In this podcast, we explore the world of energy harvesting and discuss ways to not only harvest energy, but also use it in electronic applications. This podcast, based on a popular webinar, delves into the bascis first, describing ambient energies available, then moves on to challenges in converting and storing energies. We will finish off by examining the new low power converter ICs that can be p...

Applications depend on certain or fixed capacity values to achieve a desired performance. However, ambient temperature, structural changes or component tolerances play an important role. Today we will discuss an overview of the most important factors and how these can be reduced by using a different material or external influences.

Our last podcast introduced ferrites and the basics of EMC. Today we finish with a discussion on insertion losses and calculations and close with clamp-on ferrites. Click here to watch the complete WEbinar on demand, or visit Würth Elektronik online at www.we-online.com/webinars.

In today's podcast, we discuss the basics, along with an overview of EMC, details on chip bead ferrites, and how to correctly read datasheets associated with ferrites. Click here to watch the complete WEbinar on demand, or visit Würth Elektronik online at www.we-online.com/webinars.

Energy-efficient devices are important components for saving resources and protecting the environment. The more efficient the electronics, the longer the battery service life for mobile devices, and in large-scale industrial and server installations with thousands of loads, the energy requirement is clearly reduced. The basis for energy-efficient devices is essentially influenced by the power supp...

Anymore, passive components that are only AEC-Q200 tested are not enough for the use in automotive application. Many more tests are needed for qualification for a good design and high quality component because without electronics, our vehicles would not operate. In this podcast, we discuss a few little design tips using passive components that are adequate enough to pass AEC-Q22 qualifications and...

Even though a switching regulator may produce a constant output voltage at the end of the development phase, often, designers encounter unpleasant effects, such as unwanted oscillations, at the input. So why does the input of the switching regulator tend to oscillate under certain circumstances? In this podcast, we examine "negative" resistance and come to the understanding that the sign is based...

While Press-Fit is becoming more widely known in the industry, do the masses of designers really understand the benefits of using the technology? In this interview with Ben Arden, Business Development Manager for the Electromechanics Division at Würth Elektronik's, Ben explains the advantages and uses of REDCUBE Press-Fit components.

Today, an innovative sensor system contains so much more than just the single sensor cell. The ongoing miniaturization in microelectronics development makes it possible to design Application Specific Integrated Circuits, or ASICs, with remarkable performance and minimal size. In today's podcast, we will show that besides an analogue to digital converter, we can also integrate complex digital signa...

A whisker is a crystalline structure of material that appears on tin surfaces. This well-known phenomenon was discovered in the early 1950's, and new legislative actions to avoid lead in electronic components has lead to the return of this whisker problem. These whiskers may reduce the isolation resistance and additional problems arise when the whiskers break and short the printed circuit board or...

EMC ferrites are widely used on many PCBs today. In this podcast, we'll discuss the influence of DC bias and explain the differences between the old measurement type and new extended measurement type. We also discuss the influence of temperature and compare the surface mount ferrite to the surface mount ferrite for high frequency applications, then finish with the pulse current detection of the WE...

Multilayer chip antennas are a preference for engineers, who are restricted by cost, time and space requirements in wireless system designs for handheld devices. In this podcast, we will show how even non-RF engineers can easily incorporate the antenna into new designs without special RF design knownedge. We also focus on how to match chip antenna with the rest of the circuit and give special cons...

Output filters are often used for noise suppression, which may have an influence on the control loop. To prevent output power losses, it may be necessary to compensate the control loop. No matter what switching regulator topology is used, as a result of the parasitic series resistor ESR, and the parasitic inductance ESL, of the output capacitor, the output current causes an undesired residual ripp...

Switching controllers exhibit a residual ripple in their output voltage, which disturbs electronic devices, and may cause electromagnetic interference. Output filters are often used for interference suppression, which may exert an influence on the control loop. Compensation of the control loop may be required to prevent losses in output power.
