Features
 
Resistance value changes in linearly positive way to temperature.
Quick response to the change of temperature.
Suitable for both reflow and flow solderings.
Products with lead free termination meet EU-RoHS requirements.
EU-RoHS regulation is not intended for Pb-glass contained in electrode, resistor element and glass.
