Newbie! Need transformer recommendations? [Copy link]

Testing the driving circuit of an ultrasonic transducer, the signal is 40khz pulse, the simulation circuit is as follows, I want to find a suitable 40khz pulse transformer, I can't find a suitable one on the Internet, and it costs 500 to find someone to design it. Does anyone have any suitable transformer models or reliable transformer design factories and merchants? I need it these days. Balls !

The input and output parameters of the 40khz pulse transformer should be sorted out and provided to the transformer manufacturer. It is not difficult to make it, depending on your requirements.

The quantity is small and the price is reasonable

Yes, you can consult the manufacturer of high-frequency small transformers.

There should be people who can customize it on places like Taobao.

If the manufacturer wants a certain quantity, they will make it for you. Or if there is hope for a certain quantity, some samples are free of charge.

There are also small devices and methods for winding transformers by yourself. But I haven't tried it.

I searched on Taobao and found that there are relatively few merchants making pulse transformers. I found one or two merchants who can make them, but the design fee is about 500 yuan, which seems a bit expensive. Since it is a graduation project, this price is a bit unaffordable. So, I want to see if anyone has any recommended transformer models or pulse transformer customization factories or other solutions.

First determine the specific needs. Without needs, there will be no indicators, and naturally there will be no "design". Blind buying is just luck.
