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. It is

attractively priced and available on 7" reels of 4000 pieces.

* 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.
