Thermal Sensors/NTC Flat chip Thermistors NT73
Coating color : Pink
Construction
Thermal Sensors/NTC Flat chip Thermistors NT73 Construction
1. Protective coating
2. Thermistor film
3. Inner electrode
4. Ni plating
5. Solder plating
6. Ceramic substrate
 
Features
 
SMD type thick film NTC chip thermistors.
Thinner (0.5mm in 1608, 2012 sizes,0.6mm in 3216 size) than the multilayer type.
Excellent mountability due to higher mechanical strength.
Excellent mountability due to its solder plating at the terminal section.
Suitable for both flow and reflow 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.

Resistance-Temperature Characteristic

Thermal Sensors/NTC Flat chip Thermistors NT73 Resistance-Temperature Characteristic The resistance-temperature characteristics of a thermistor can be approximated by equation 1.

R=R0 exp{B(1/T-1/T0)} (eq1)

R : resistance at absolute temperature T (K)
R0 : resistance at absolute temperature T0 (K)
B : B constant (K)

*T(K)=t()+273.15
