Terminations: Wrap-around terminations on CR resistors have good ‘leach’ resistance properties. They will withstand immersion in solder at 260°C for 30 seconds. Marking: All relevant information is recorded on the primary package or reel. Thickness: The thickness of these devices depend on the size of the chip. The table below shows the standard substrate thickness used (mm). STYLE 0805 1206 Planar 0.4 0.5 Wrap-around 0.4 0.5 F = Wrap-around; G = Planar Gold.

APPLICATION NOTES: Mounting This chip resistor is ideally suited for handling by automatic methods due to its rectangular shape and the small dimensional tolerances. Electri- cal connection to a ceramic substrate or to a printed circuit board can be made by reflow soldering of wrap-around terminations (e.g. suffix ‘F’ in CR0805F). The ‘F’ terminations provide good leach properties and ensure reliable contact. Due to the robust construction, the resistor chip can be immersed completely 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 other wire-leaded components on the other side.
