3503/3504 Series Resistors

TE Connectivity's (TE) aluminum nitride thin film power resistor type 3503 and 3504 series range offers a high power-to-size ratio of 2 W in the 1206 size (3503 series) and 6 W in the 2512 size (3504 series). These resistors are introduced as first-to-market with the high power dissipation capability available for 1206 and 2512 chip sizes. They are driven by the progressive miniaturization trend influencing the market, as well as the requirement for more reliable and thermally-conductive products.

The 3503 and 3504 series offer TCR at ±50 ppm/°C and resistance tolerance at ±1% as standard. They also have accurate and uniform physical dimensions to facilitate automatic placement methods, and the resistance values are within the IEC 63, E96, and E24 value grids.

Benefits

• Higher operating temperature capability enables high power dissipation capability for the component
• PCB space-saving for the customer by being able to use fewer components to dissipate a higher power level
• Offers high precision considering the level of power linked to the products, leading to less variation in the resistance of the components given the temperature to which it is exposed
