Packaging

GPCF Resistors are supplied paper taped and reeled as per IEC 286-3.

Application Notes

GPCF 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.

Wrap-around terminations provide good leach properties and ensure reliable contact. Due to the robust construction, the GPCF 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.

GPCF resistors themselves can operate at a maximum temperature of 155°C. 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.
