2 Watts at
70°C 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 Type 3521 Series 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. Characteristics – Electrical Power rating at 70°C 2W Max RCWV* 250V Max overload voltage 500V Resistance Tolerance 1% Resistance range 1R0 - 1M0 Temperature Coefficient <10R ±200PPM 10R – 1M0 ±100PPM >1M0 ±200PPM Temperature range -55°C ~ +155°C Ambient temperature 70°C * 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.
