Notes:

•

MF-NSHT models are intended for reflow soldering (including, but not

limited to heating plate, hot air, IR, nitrogen, and vapor phase).

•

Wave soldering is permissible only if the device is on the top of the

PCB, opposite the heat source.

•

Hand soldering is not recommended for these devices.

•

All temperatures refer to the topside of the device, measured on the

device body surface.

•

If reflow temperatures exceed the recommended profile, devices may

not meet the published specifications.

•

Compatible with Pb and Pb-free solder reflow profiles.

•

Excess solder may cause a short circuit.

•

Please refer to the Multifuse® Polymer PTC Resettable Fuse Soldering

Recommendations document for more details.
