Black TypeA 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.
Green TypeA 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.

Note:The cumulative tolerance of 10 sprocket hole pitch is ± 0.2 mm.1. Carrier camber shall not be more than 1 mm per 100 mm through a length of 250 mm.2. A & B measured 0.3 mm from the bottom of the packet.3. T measured at a point on the inside bottom of the packet to the top surface of the carrier.4. Pocket position relative to sprocket hole is measured as the true position of the pocket and not the pocket hole.5.
Power Derating CurveNote:The power derating curve is a guidance based on a conservative design model. The ULR is a solid metal alloy construction that can withstand signifi 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 signifi cant design parameter due to the heat limitations of the solder joint.
