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.

2.5A

Max. overload current (Jumper)

10A

Max working voltage

250V

Max overload voltage

500V

Dielectric withstand voltage

500V

Temperature range

-55°C ~ +155°C

Ambient temperature

* 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.

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.
