Title: :) heater
Post by: GigaJoe on January 22, 2019, 06:52:23 pm
I need a heater for my owen ,   not a powerful one , just a few watts .... 
so ... i like mosfet as a heater, it easy to manage ... but i run out from any reasonable TO220 packages ....

and here we are:
https://www.aliexpress.com/item/-/32902467808.html (https://www.aliexpress.com/item/-/32902467808.html)
8.3 US cents , and free shipping :)
I'm have no doubt, about label,  just a hope it will hold 20Volt, and a few hundred mA.  (would be really disappointing if not, will open the case, for money return, then :)  )

But I really grinned, have fun,  imaging cost of manufacturing, distributing, selling margin, and shipping cost .....   so what ... it less then 1 cent then ... i really really not understand economics in this case ... Consider quality of product and volume to sell ...

I'd rather a tealight in a flower pot.
