The 3522100RJT is an SMD power resistor from TE Connectivity's Type 3522 Series, engineered for compact, high-power applications with a 3W power rating at 70°C ambient temperature. It features a maximum working voltage of 250V, maximum overload voltage of 500V, and dielectric withstand voltage of 500V, with a rated current of 2.5A and maximum overload current of 10A. The resistor operates across a wide temperature range of -55°C to +155°C and is constructed with a high-purity alumina substrate with matte tin over nickel barrier termination. Its compact dimensions (6.35 mm × 3.20 mm × 1.10 mm) combined with high power density make it ideal for automated placement in volume production, high-frequency operations, and applications requiring reliable thermal performance in space-constrained designs.
