Hi
I want to simulate a circuit using PTC in LTspice. But, the manufacturer (Littelfuse) has not given the spice model for PTC. My question is,
1.Does anyone have unencrypted spice model for PTC?
2.If I get an unencrypted spice model, can I edit that model to the one which I use?
The PTC which I use is AHEF500. Its electrical parameters are:
Trip time- 9 sec
Max Voltage-32V
Ihold- 5A
Itrip-10A
Resistance- 15m ohm (minimum), 40m ohm (maximum).
Can anyone help me in this? Thanks in advance.
P.S
I have referred the spice model given by Vishay, but they are encrypted.
