Part number
| 2. | HAS—— Special sensors for home appliances. |
| 3. | 104 —— Nominal resistance of thermistor, e.g. 104 indicates that the nominal resistance of the thermistor is 10*104 (Ω). |
| 4. | J —— Resistance error (precision) of thermistor, e.g. J indicates the nominal resistance error of the thermistor is ± 5%. |
| 5. | 399 —— B25/50 value of thermistor, e.g. 399 indicates the thermistors material factors B25/50 value is 399*10K. |
| 6. | F —— B25/50 error (precision) of thermistor, e.g. F indicates the thermistors B25/50 value (precision) is ±1%. |
