Black Type
A low TCR resistance alloy plate with plated connection
bands is protectively coated and numerically marked with
the resistance value, as described in Product Marking. This
version has standard plated connection and is suitable for
wave or IR re ow soldering processes.

The cumulative tolerance of 10 sprocket hole pitch is ± 0.2 mm.
Carrier camber shall not be more than 1 mm per 100 mm through a length of 250 mm.
A & B measured 0.3 mm from the bottom of the packet.
T measured at a point on the inside bottom of the packet to the top surface of the carrier.
Pocket position relative to sprocket hole is measured as the true position of the pocket and not the pocket hole.

Note:
The power derating curve is a guidance based on a
conservative design model. The ULR is a solid metal
alloy construction that can withstand signi cantly greater
operating temperatures than the conservative model
permits. The protective coating will operate up to
260°C and the alloy can withstand in excess of 350°C.
Therefore, the system thermal design will be a more
signi cant design parameter due to the heat limitations of
the solder joint.

Green Type
A low TCR alloy plate is grooved to set the nal resistance.
The lower faces are solder plated for connections, and the top
surface is protectively coated and numerically marked with the
resistance value, as described in Product Marking. This part
is suitable for wave and IR re ow soldering processes. Wave
re ow requires the solder mask to be dimensioned according to
page 2 using the W and D dimensions of the part.
