Precision Surface Mount Resistors
PCF Series
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.
