“Awesome little device, I got some of these to make a low-powered heater that can run on a power bank.
I sandwiched the PTC element between 2 x 5mm thick plates of Aluminium to create a thermal mass effect battery, which works well.
I would highly recommend these PTC elements to anyone wanting heating in their project.
Great price with next-day delivery.”
“I bought a few of these to make a low-voltage, low-temperature heater without the need for complicated PID control. Pi Hut was out of stock initially so I requested an email notification from Pi Hut when they returned to stock. I received an email only 2 days later and so bought 5 of them! The price of 5 was about the same as buying one on Amazon from a different seller. 2 days after I placed the order they arrived...individually sealed and well packaged in a cardboard box. Overall great service and fair pricing for decent quality items.”
“A curious product!
See the attached graph showing the heat up and cool down times based on some very basic testing.
The device was switched on at time 0s and switched off 287s into the test. The temperature was measured using a K-type probe pushed inside the device.
Left hand axis = Current in amps @ 5V (starting around 0.4A)
Left hand axis = Power in Watts (starting around 2W)
Right hand axis = Temperature in deg C”
