1.1
SMD NTC thermistors can be provided with a nickel barrier termination or on special request with
silver-palladium termination. The usage of mild, non-activated fluxes for soldering is recommend-
ed as well as a proper cleaning of the PCB.
The nickel barrier layer of the silver/nickel/tin termination (see figure 1) prevents leaching of the
silver base metalization layer. This allows great flexibility in the selection of soldering parameters.
The tin prevents the nickel layer from oxidizing and thus ensures better wetting by the solder. The
nickel barrier termination is suitable for all commonly-used soldering methods.
Note: SMD NTCs with AgPd termination are not approved for lead-free soldering.
