The AC1210FR-07274RL from YAGEO is an AEC-Q200 qualified automotive-grade thick-film chip resistor in the 1210 package size, offering 274Ω resistance with ±1% tolerance. Part of YAGEO’s AC series automotive resistor line, this device is specifically designed and qualified to meet the rigorous requirements of the AEC-Q200 standard for passive automotive components. It is constructed on a high-purity automotive-grade alumina ceramic substrate using advanced moisture-resistant thick film technology, ensuring exceptional long-term stability and reliability in harsh automotive and industrial environments. The resistive element is laser-trimmed to achieve the tight ±1% tolerance with a ±100ppm/°C temperature coefficient. With a 0.5W power rating at 70°C ambient and 200V working voltage, this resistor handles higher voltage and power requirements than smaller packages. The 1210 size (3.2mm × 2.5mm) provides a balance of power handling capability and board space efficiency. The AC series features enhanced sulfur resistance compared to standard thick-film resistors, making it suitable for use in environments with high sulfur content. Fully qualified to AEC-Q200, with PPAP documentation available on request, the AC1210FR series is trusted for use in automotive powertrain, body electronics, ADAS systems, and infotainment modules, as well as industrial power supplies and high-reliability electronic systems.

The AC1210FR-07274RL operates based on the fundamental principle of electrical resistance in a conductive material, following Ohm’s law (V = I × R). The resistive element is a thick film of ruthenium oxide (RuO₂) based conductive paste that is screen-printed onto a high-purity alumina ceramic substrate and fired at high temperature. The resistance value is determined by the sheet resistance of the resistive material and the physical dimensions of the resistor pattern (length and width). Laser trimming during manufacturing precisely adjusts the resistance by cutting a calibrated notch into the resistor film, achieving the tight ±1% tolerance specification. An overglaze protective coating is applied over the resistor element to protect against mechanical damage, moisture, and environmental contamination — a critical feature for automotive-grade reliability. The terminal electrodes consist of multiple layers: an inner silver-based conductor for connection to the resistor film, a nickel barrier layer to prevent solder leaching (the dissolution of silver into molten solder during reflow), and an outer tin plating for excellent solder wettability and corrosion resistance. When current flows through the resistor, the resistive material converts electrical energy into heat through the Joule heating effect (P = I²R). The 0.5W power rating indicates the maximum power the resistor can safely dissipate at 70°C without exceeding rated temperature limits. Above 70°C, the power rating is derated linearly to zero at 155°C to prevent overheating and ensure long-term reliability. The automotive-grade construction ensures stable resistance values even under temperature cycling, humidity, and vibration conditions encountered in automotive applications.

Terminal Type Description
Terminal 1 Passive Resistor end termination — non-polarized, bidirectional
Terminal 2 Passive Resistor end termination — non-polarized, bidirectional

Note: Chip resistors are non-polarized passive components — either terminal can be connected to the higher or lower potential side of the circuit without affecting performance. Termination structure: inner Ag conductor + Ni barrier layer + outer Sn plating (Pb-free, halogen-free).
