SMD POWER RESISTORS Type 3522 Series Key Features 3 Watts at 70C Small size to power ratio Supplied on tape Value marked on resistor Available via distribution 500 volt maximum overload 250 volt working voltage Terminal finish matte Sn over Ni 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. Characteristics - Electrical Power rating at 70C Rated current (Jumper) Max. overload current (Jumper) Max working voltage Max overload voltage Dielectric withstand voltage Temperature range Ambient temperature 3W 2.5A 10A 250V 500V 500V -55C ~ +155C 70C * 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. 9-1773463-7 Rev.

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.
