The RT0402BRE0710KL consists of a ceramic substrate coated with a thick film resistive layer, typically made of ruthenium oxide. This layer is laser-trimmed to achieve the precise resistance value of 10 kΩ. The resistor features nickel barrier layers and a tin-plated termination to ensure excellent solderability and long-term reliability. When current flows through the resistive layer, it creates a voltage drop proportional to the resistance value, following Ohm's Law (V = IR). The thick film construction provides stable performance under various environmental conditions, including temperature fluctuations and humidity. The compact design minimizes parasitic inductance and capacitance, making it suitable for high-frequency applications.
