Caution

• Avoiding the measurement error caused by the current passing through the thermistor chip leads the component to heat itself.
• When the soldering iron is welded, the distance between the soldering point and the coating layer is at least 2mm, the soldering temperature should be lower than 360 C, and the soldering time is <3s.
