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.
Precision Surface Mount Resistors
Solderability
The terminations have an electroplated nickel barrier and tin coating. This ensures excellent 'leach' resistance properties and
solderability.
Wrap-around terminations provide good leach properties and ensure reliable contact. Due to the robust construction, the PCF can
be immersed in the solder bath for 30 seconds at 260 C. This enables the resistor to be mounted on one side of a printed circuit
board and wire-leaded components applied on the other side.
PCF resistors themselves can operate at a maximum temperature of 125 C (see performance above) (155 C for High Power grades).
For soldered resistors, the joint temperature should not exceed 110 C. This condition is met when the stated power levels at 70 C
are used.
