Operating Temperature Range
The chips can operate at a maximum temperature of 155°C
(see Performance Data). For soldered chips, the joint
temperature should not exceed 110°C. This condition is met
when the stated power levels at 70°C are used.
Mounting
This chip resistor is ideally suited for handling by automatic
methods due to its rectangular shape and the small
dimensional tolerances. Electrical connection to a ceramic
substrate or to a printed circuit board can be made by wire
bonding (eg suffix ‘G’ in PCR0805G) or by reflow soldering of
wrap-around terminations (eg suffix ‘F’ in PCR0805F). The ‘F’
terminations provide good leach properties and ensure
reliable contact. Due to the robust construction the resistor
chip 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 and other wire-leaded components on the
other side.
