I’ve been looking for a PTC Thermistor on DigiKey that can protect different DUTs, like batteries and external chargers, and is connected to a programmable electric load, but I haven’t found any products that meet my requirements. I request the following:
Has two wires that are 20-100cm long for practical use in laboratories
Can easily assemble and disassemble (for example, thermal tape)
T_sense: The temperature sense should be at 80-90 degrees Celsius
Should be able to operate at up to 150 degrees Celsius. 125 is okay as well, I think
Does anyone know of any thermistors that meet these requirements? Thanks in advance!
PTC thermistors come in a couple of distinct flavors; a linear variety used for sensing purposes and a non-linear variety used for temperature/current limiting. The PTC thermistor product family would be a likely place to look, however.
There are also PTC fuse products, which serve similar though different purposes.
Defining the specific application, its requirements, and desired electrical behavior of the component in question would be important to identifying a suitable product.
