The 3521680RFT is a 2-watt SMD power resistor from TE Connectivity's 3521 series, qualified to AEC-Q200 Grade 4 standard for automotive applications. It features a compact thick film chip design with a resistance range of 1O to 10MO, tolerance options of ±1% or ±5%, and operates reliably across a temperature range of -55°C to +155°C. The device is rated for a maximum working voltage of 250V and maximum overload voltage of 500V, with a dielectric withstanding voltage of 500V. Its small size-to-power ratio, short lead structure, and matte tin-over-nickel terminal finish make it suitable for high-frequency operations and automated assembly on 7-inch reels. The 3521680RFT is ideal for automotive and industrial applications requiring robust, high-reliability resistive components in compact form factors.
