I am working on a low power project that uses a rechargeable 3.7V lithium-ion coin/button cell (probably in the 2032 size range). Standard discharge current is <1mA with pulses up to 30mA. Standard change current is ~10mA.
Although it's highly unlikely over the lifetime of the product, the...
I appreciate everyones' responses.
A few other details I neglected to mention:
1. The total wire length (before breaking) can be up to 12 feet (4 meters). It will also be coiled (sorry, that was an important detail).
2. The wire will be moved around and near various materials (metal, plastic...
I need to sense a change in length of a single wire in free space. I only have access to one end of the wire. TDR would be a great option, but this is not a transmission line.
I don't need to measure the length accurately, I just need to know that it changed from one length to another length...
Can anyone explain what is actually happening in this video by ElectroBoom at the 7:10-7:40 mark:

Gain looks correct, I've seen this used a lot in PFCs to measure the line voltage. See the attached spice file.
Multiple high resistance resistors (usually size 1206 or greater I believe) are used for safety and single fault tolerance.
Much like treez in:
https://www.edaboard.com/threads/comparator-that-latches.270535/
I need a comparator that latches when an over current condition is sensed. Here is the basic operation flow:
1. CSA output fed to comparator.
2. When CSA output is greater than specified value, comparator...
After reading more about the Wurth Redcube Press Fits, it looks like they may be my best option. My original concern with them was joint strength and connection resistance, but according to the docs:
Pressing the pins into the PCB, a high friction between pin and plated through-hole generates a...
@KlausST
You're correct on the construction. The metal is 2mm thick and the screw size is 10-24. I did try google lens on it, no luck. I don't need it to be exactly this. This would work, but all I really need is a single 90degree bend.
@FvM
I bet you're right that it's not off the shelf, but...
Thanks for the reply, but that's not what I am looking for. I need it to be a "right angle" with both sides threaded.
Or Keystone part number 4334 with legs to solder to the PCB and >100A current capacity.
Check your SolderMaskExpansion Rules.
If it's at a component level:
Try deleting the component from the PCB and re-Updating the PCB from the schematic.
(Or try Right Click > Component Actions > Update PCB Components from PCB Libraries)
I also find swapping to 3D is an easier way to inspect...
I'm looking for a PCB screw terminal like this (or this exact one):
to connect a PCB to a busbar in a high current application. These are from a Meanwell RSP-2000-12.
Typically I would go to Keystone for something like this, but they don't have anything that is:
a. Soldered to the board
b...
I am attempting to take some loop measurements so I can tune a digital compensator for DAB converter (12V to 300V, 600W, 150KHz). The output voltage is sensed using an isolated amplifier (AMC1202).
The method I am using is similar to the following application note...
I found some issues with my spice circuit that were causing me to ask these questions. I believe I have rectified the issues and have it running (see attached). This simulation also gradually increases the DC of the gate driver signals, which reduces the initial currents in the circuit.
I know...
I'm looking into a bidirectional converter design for charging a battery bank when a mains connection is available, and operating as an inverter when mains is not available.
The design is similar to the following picture:
The operation in Direction 1 (as a battery charger) is clear to me:
1...
