  • How are you be affected by the shortage of multi-layer ceramic capacitors?

    The global shortage in Multi-layer Ceramic Capacitors (MLCCs) is creating a squeeze on getting them. There’s an industry-wide shortage of MLCCs, and lead times, where quoted, are up to 50 weeks on new orders. Companies are struggling to get their hands…

  • What defines "LOW ESR"?

    A parts list calls for LOW ESR capacitors (in the TL499A switchmode controller PSU). It has been suggested that 105 degC capacitors could be substituted, but I figure I should also choose those that start off in the ball-park. So what actually defines…

  • Your Mission Should You Decide to Accept it: Take My Polymer Capacitor Quiz and Pass It!

    Mission Impossible was always a favorite TV show of mine. It was a fast paced thriller for its time (in black and white, I believe) and everyone on the IM Force did their job flawlessly, especially the gadget/electronics guy. I also liked the opening…

  • Measuring Capacitor Characteristics

    Introduction Background Why does ESR matter and why measure it? Differences between the BA6010 and LCR Meters Is it worth using the BA6010 for measuring Capacitors? Capacitors and Specifications Results Tantalum…

  • Seeking Someone to Write a Tutorial on Charge Pumps Including Building Some Examples

    I am interested in sponsoring a member to write a tutorial on charge pumps. I'd like the member to: a) explain what they are b) explain how they work c) build a few variants of charge pumps. I would buy all the parts. And I would throw in a "surprise…

  • Building Kelvin (4-Wire) Test Leads

    Introduction This short blog post discusses an attempt to make test leads for hopefully better measurements! Measuring small resistances is really difficult with the usual 2-wire measurement with multimeters. The multimeter will measure the resistance…

  • Arduino: R-2R: "Resistance is..."?

    Another diversion - I'm going all round the houses here. Who would have thought that there could be so much to a few simple resistors arranged in a network? This time I'm playing with the simulator. When I did the hardware in a previous blog, I mentioned…

  • Seeking Your Opinion: The Proposed Kit for the Polymer Capacitor Projects Scheduled for March

    As part of my interest in providing learning experiences and useful information to the element14 community on polymer capacitors, I am planning for March a polymer capacitor project with a free kit. My goal is to get some polymer capacitors in your hands…

  • So You've Taken The Polymer Capacitor Quiz. Next Up: What Do You Really Want To Learn About Polymer Caps?

    Greetings All Polymer Capacitor Quiz Takers! I enjoyed putting together the Polymer Capacitor Quiz, as much as some of you (I think) enjoyed taking it. I think we both learned something about these little marvels of electronic engineering. But I think…

  • Seeking Proposals for Capacitor, Inductor or Resistor Projects
