Ps.:can be tailored according to clients’ demand

Features:
1. Body size: Φ3.5mm
2. resistance range:100Kohm 200Kohm
3. B value range:3975～4200K
4. -30 ~ +120℃operating temperature range
5. RoHS compliant

Recommended applications:
Temperature sensor,home electronics,electronic clock,electric table-board,automobile electrics,CPU fan etc

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
