Characteristics:

Part no.	Zero power resistance @ 25°C	Tolerance of R25	B value		Tolerance of B value	Max. Power Dissipation At 25°C	Dissipation Factor	Thermal Time constant	Operating temperature range
Part no.	R25 (KΩ)	( ±%)	(K)		(±%)	Pmax(mW)	δ(mW/°C)	τ(Sec.)	(°C)
WS-MFB－1004-4400	1000	1,2,3,5,10	25/50	4400	1,2,3,5	100	≧2	≦9	-40～+300
WS-MFB－1384-4400	1388	1,2,3,5,10	25/50	4400	1,2,3,5	100	≧2	≦9	-40～+300

Ps.:can be tailored according to clients’ demand

operating current:

In order to make the test more accurate, the running current should be as less as possible. The following formula is suggested:
I＝sqrt(0.005δT^2/(B*R))
PS.:1.sqrt is for square root
2. δ is for dissipation constant in mW/℃
3. T is for temperature in Kelvins
4.B is for the index of the thermal sensitivity
5.R is for zero-power resistance in KOHM
6.final current is in mA
