Note:
● Refer to the sign description for all the models.  
● Technical parameters: B value (25 / 50℃) error: for nominal resistance precision of ±1%, B value error is ±1%. All the other B value errors are ±2%.

Note:
● As MF 52 product has small size and solder joints, it cannot bear excessive tensions, so it cannot be pulled excessively.
● During welding, the solder joint shall be at least 5mm away from the lead root. The welding duration shall be as short as possible, so as to ensure the assembly quality.
