Technical   Data
 
 Resistance（R*5）
Requirement：R*5 within the scope of the standard 
Test method： *5℃±0.*5℃  constant temperature tank test
 
4. B-value
Requirement： B value within the scope of the standard
Test method：In high accuracy constant temperature tank, code according to the B value measured at both temperature resistance, then the following formula.
Bt1/t2=ln (Rt1/Rt2)/(1/(t1***3.*5)*1/(t2***3.*5))
 
Insulation resistance
Requirement：≥ **0MΩ
Test condition：At room temperature, applied voltage **0V DC
 
withstand  voltage
Requirement：No breakdown
Test condition：At room temperature, applied voltage AC ***0V 5s for a second, max current 0. 5mA.
 
Thermal dissipation factor（δ）
δ≤2.5mW/℃；
Requirement：δ≤2.5mW/℃；
Test method：The product will be join with the following circuit at *5±0.5℃ in still air.

Thermal time Constant（τ）
Requirement：CWF1τ≤7s，CWF2åž‹τ≤*0s，CWF3τ≤9S
Test method：In the water, When the products be put into the water at *5℃ from the water at *0℃, Thermal time constant is the time that cost by the resistance becoming to be the value at*3.2%.
 
Max.rated power
P≈**7mw
P≈δ×(*0℃－*5℃)
Requirement：P≈**7mw
