Type RP73 Series
The RP73 Resistor series is a stable
Thin Film chip resistor range offering
increased power dissipation, higher
temperature capabilities and increased
working voltages compared to the
standard RN73 series.
The resistor is produced by sputtering a
metal film onto high grade alumina and
protecting with 3 complete printed
layers.
Values are normally offered in E96 and
E24 series.
The RP73 Resistor has accurate and
uniform physical dimensions to reduce
placement problems.
Due to special technologies employed
to produce tight tolerances, low TCR
devices at high values the RP73 series
is not individually part marked.

Handling Recommendations
When flow soldering - the land width must be smaller than the chip resistor width to properly control the solder
application. Generally, the land width can be chip resistor width (W) x 0.7 to 0.8. When reflow soldering - solder
application amount can be adjusted.
Thus the land width can be set to W x 1.0 to 1.3.
