MOUNTING
The thermistors are suitable for all standard assembly processes like crimping, soldering, welding. The parameters of the assembly process should be chosen in accordance with the lead-wire material (tinned nickel) and validated in application. The mounting process should be in compliance with the following guidelines and recommendations:
• Peeling forces on the leads should be reduced to a minimum and should never exceed 3 N
• Avoid large temperature gradients between the welding region and the sensor
PACKAGING
• Bulk components are delivered in boxes of 500 components
