How many PTC thermistors can be connected simultaneously?
The maximum number of PTC thermistors that can be connected to Thermoflagger™ is roughly 30.
If more than one PTC thermistor is used, consider variations in IC and PTC thermistor characteristics to ensure that detection at the set temperature is not hindered by the increase of the combined resistance.
For reference, TCTH02xxE and Murata's PTC Thermistor (POSISTOR): Simulate PRF18BC471QB5RB.
The detection temperature may fluctuate depending on the number of PTC thermistors connected and the ambient temperature of IC・PTC thermistor. Be sure to thoroughly verify the detection temperature.
