Type RH73 Series
The RH73 Series is a stable high value
chip resistor range offering various
power dissipation relating to chip size.
Tyco is pleased to offer this innovative
range of chip resistors up to 100 Gig.
The RH73 series is suitable for flow and
reflow soldering. It has a thick film
resistor element and three layers of ter-
minal material to ensure high reliability.
It is attractively priced and available on
7" reels with 1000 pieces per reel.

For resistors operated in ambient temperatures above 70°C, power rating must be derated in accordance
with the curve right.
Values above 100 Meg ohms do not have glaze coat. This is to avoid reaction with a Galvanic coating on the
terminals. This does not effect the the resistor performance.
