Power Rating:
The high resistance value of these devices is such that power dissipation is always small. The rating is therefore determined by voltage considerations
only, as shown in the table above.
Contruction:
Thickness:
The resistor material is screen printed onto a 96% alumina substrate and
covered with a protection comprising of a glaze followed by an organic
coating. This construction gives an insulated device.
Terminations:
The thickness of these devices depend on the size of the chip.
The table below shows the standard substrate thickness used
(mm).
Wrap-around terminations on HR resistors have good ‘leach’ resistance
properties. They will withstand immersion in solder at 260°C for 30
seconds.

APPLICATION NOTES:
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 reflow soldering of wrap-around terminations. 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. The presence of moisture will not damage the resistor in any way.
Ordering Data
Specify type, reference, etc. as indicated in this example of a HR0805F 100M ohms K resistor with wrap-around
terminations and packed in a waffle pack. 1005 is available in Waffle Pack only.
