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

Features:
1. Body size: Φ1.1mm X2.0mm
2. resistance range:5Kohm & 10Kohm & 20Kohm
3. B value range:3200～400K
4. -30 ~ +120℃operating temperature range
5. RoHS compliant

Recommended applications
Rice cooker, microwave oven, electric cooker, coffee pot, electric blanket, soy sauce pot, toaster etc.
