Solderability
The terminations have an electroplated nickel barrier and tin coating. This ensures excellent 'leach' resistance properties and
solderability.
Packaging
PCF Resistors are supplied taped and reeled as per IEC 286-3.
Application Notes
PCF resistors are ideally suited for handling by automatic methods due to their rectangular shape and the small dimensional
tolerances. Electrical connection to a ceramic substrate or to a printed circuit board can be made by reflow or wave soldering of
wrap-around terminations.
