TE Connectivity is pleased to introduce this low cost high power device, suitable
for auto placement in volume and for most applications, including high
frequency operations, owing to the short lead structure. Supplied as standard
on 7 inch Reels of 2000 pieces per reel.

* Rated continuous working voltage (RCWV) shall be determined from
RCWV = Rated Power x Resistance Value, or Maximum RCWV listed above,
whichever is less
**Recommended Circuit Board Design - If this device is anticipated to run at full
continuous power then action to improve the cooling should be taken. This can
be a metal substrate, copper pad left under the chip, an opening in the PCB or
enlarged silver conductor pads each end.

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.
