NTC POWER THERMISTOR, SCK SERIES
Meritek
Thermal dissipation coefficient( δ )
The thermal dissipation coefficient is the ratio, normally
expressed in milliwatts per degree C (mW/oC), at a specified
ambient temperature, of a change in power dissipation in a
thermistor to the resultant body temperature change.
(δ =VXI/T)
Thermal time constant( t )
The thermal time constant is the time required for a
thermistor to change 63.2 percent of total difference between
its initial and final body temperature when subjected to a
step function change in ambient temperature under zero-
power condition and is normally expressed in seconds.
Material constant(B)
The material constant of a NTC thermistor is a measure of
its resistance at one temperature compared to its resistance
at a different temperature. Its value may be calculated by the
formula shown below and is expressed in degrees kelvin
(oK ). The reference temperature used in this formula for
determining material constant rating of Meritek’s thermistor
is 298.15'oK and 323.15 oK B=Ln(R1/R2)/( 1/T1-1/T2 )
Temperature coefficient of resistance (α)
The temperature coefficient of resistance is the ratio at a
specified temperature, T, of the rate of change of zero-power
resistance with temperature to the zeropower resistance of
the thermistor. The temperature coefficient is commonly
expressed in percent per degree C(%/oC). α =I /R dR/dT
Surge energy
Surge energy is the maximum energy of pulses.
The thermistor is capable of tolerating surge energy more
than 1000 times with the resistance changing rates within
± 10%. This energy varies with voltage and capacitance.
Storage temperature range:- 40 to +125 oC
Operating temperature range:- 30 to +125 oC
DERATING CURVE OF SURGE CURRENT
LIMITING THERMISTOR
The maximum power of a thermistor will decrease with the
change of ambient temperature.(See Fig.G)
