Hot Plugging of PoE Modular Jacks

Würth Elektronik Watts Up Podcast ·

2021/10/07

Modular jacks (MJ) connectors and cables are broadly used to bring Ethernet signal up to 10 Gb/s depending on the category of the product. It is also possible to deliver power through it with PoE. In this episode, we will study if recommendations for the WE-MJ connectors can be extended up to Type 4 and demonstrate the capabilities of modular jacks in case they are accidently used as a disconnector product in a PoE application.

Multilayer Chip Antenna Placement & Matching

Würth Elektronik Watts Up Podcast ·

2021/09/30

The trend to miniaturize wireless communication devices has led to decreased PCB sizes and increased component densities. Although this shift to miniaturized technology has aided many areas of electronic design, it constrains RF front-end design. Multilayer chip antennas are an interesting choice for engineers, who are restricted by cost and space requirements in wireless system design. Low temperature co-fired ceramic (LTCC) multilayer chip antennas are formed from several layers of dielectric

Going Wireless with Magnetic Shielding

Würth Elektronik Watts Up Podcast ·

2021/09/23

Magnetic Field Interferences are increasing in electronic devices due to a number of factors including reduced separation distances of PCB’s, Integrated Circuits and many other sensitive components. Magnetically coupled communication technologies leads to more complex layout and proximity considerations. With Ferrite materials it is possible to manage and predict magnetic flux flow and thereby improve efficiency of power transfers, increase distances of near field communications and of course avoid

What Do Rated Current Values Mean?

Würth Elektronik Watts Up Podcast ·

2021/09/16

Rated current values found on datasheets serve as a guide for the selection of power inductors. However, the temperature rise in power inductors can be influenced by many factors that are not always reported in datasheets by all manufacturers giving a false sense of what the rated current values actually represent. In this podcast, we discuss how the behavior of a single inductor in different conditions demonstrates how different performance parameters may be used to gauge the performance of an

EMC Filter for DC/DC Switching Controller Optimized

Würth Elektronik Watts Up Podcast ·

2021/09/09

Modern power supplies need to reduce power loss in order to remain efficient. Switch mode power supplies and DC/DC switching controllers are state of the art and allow great efficiency, but if the design of the circuit and circuit board layout is less poor, then this can result in increased emission of radio interference voltage. In this podcast, we are discusses the systematic implementation of input filters for reducing symmetric interfering voltage in DC/DC switching controllers. Figure 1:

Ferrite Beads for Ringing Control

Würth Elektronik Watts Up Podcast ·

2021/09/02

Ringing is a common term that refers to the undesired oscillation which happens when a power semiconductor switch turns on or off in the presence of parassitic inductance and capacitance. In this podcast, learn how ferrite beads placed in series with the bootstrap pin of buck regulators can make excellent ringing control components, and when applied properly they can be used to treat the source of the high frequency noise without taking up too much PCB area.

Safe, Reliable Designs for Non-Isolated Offline...

Würth Elektronik Watts Up Podcast ·

2021/06/03

Although the majority of AC offline converters and switching converters that run from hazardous voltage, include galvanic isolation for safety, there are many applications where non-isolated circuits can be used. Where mechanical isolation protects the user and service personnel from contact with hazardous voltages, or for where both input and output voltage are on the primary side of isolated converters, the buck regulator and buckboost regulators are often more efficient, use less PCB area and
