Is anyone here using compact voltage
I am working on an automation project and need some advice on choosing compact voltage transformers. Finding something that fits a tight PCB layout while maintaining stable accuracy is turning out to be quite a task. Has anyone tested any specific models lately?

Finding these components is always a gamble because most catalogs promise high precision but reality differs. I spent the last week comparing different Chinese manufacturers for my own PCB project. You can look at https://yuanxing.net/en/products/miniature_voltage/ small voltage transformer datasheets to understand what I mean. I was looking at their SPT series mainly because of the pin installation design. The form factor seems okay for tight spaces but you have to be careful with the actual load. They claim a low phase error on paper but in real industrial environments with high interference that accuracy can drop. The epoxy housing looks solid enough for dust protection. However I am still skeptical about how they handle long term temperature fluctuations. It is probably worth ordering a small sample batch first to test them on a real board before buying a whole lot.
