The 352239RFT is an SMD power resistor from the TE Connectivity 3522 series, designed for automotive and high-frequency applications with AEC-Q200 qualification at Grade 4. It delivers 3 watts of power dissipation at 70°C ambient temperature with a maximum working voltage of 250V and maximum overload voltage of 500V, supporting a rated current of 2.5A and maximum overload current of 10A. The resistor features a compact form factor with dimensions of 6.35 mm length, 3.20 mm width, and 1.10 mm height, utilizing a high-purity alumina substrate with nickel-barrier and tin termination for reliable soldering. It operates across a wide temperature range from -55°C to +155°C and is available in tolerance grades of ±1% (E96 series) or ±5% (E24 series) for resistance values from 1O to 10MO. The device is supplied on 7-inch reels with 2000 pieces per reel and is ideal for automotive power management, high-frequency circuits, and volume production applications requiring robust, low-cost power dissipation.
