Product Model Description
MF58-103F3470
- MF58: Glass-encapsulated temperature sensing NTC thermistor
- 103: Zero-power resistance at 25 is 10K
- F: Resistance tolerance code (F-1%, G-2%, H-3%, J-5%)
- 3470: B25/50 value is 3470K
Usage Precautions
- Application: Temperature measurement and control.
- Avoid current flowing through the thermistor chip causing self-heating and measurement errors.
- When soldering with a soldering iron, the soldering point should be at least 2mm away from the glass bulb. Soldering temperature should be below 360, and soldering time should be less than 3 seconds.
- If leads are bent, the bending point should be more than 2mm away from the glass bulb to prevent damage.
- Storage Temperature: -10 ~ 40.
- Storage Humidity: 75% RH.
- Avoid storage in environments with corrosive gases and direct sunlight.
- Reseal packaging after opening.
- When using heat shrink tubing, do not use a hot air blower for shrinking. It is recommended to place the product with the heat shrink tubing into a constant temperature oven at 110 for 10-12 minutes.
