The ASC0402-10KFT10 from Welwyn Components (TT Electronics) is a surface-mount thick film resistor engineered for reliable operation in sulphur-bearing and harsh environments. Part of the ASC Series Anti-Sulphur Chip Resistors, this component is specifically designed to resist sulphide growth that can cause premature failure in standard resistors.
With a 10 kΩ resistance value, ±1% tolerance, and a compact 0402 package, the ASC0402-10KFT10 is well suited to high-density designs in industrial, automotive, and roadside electronics, where environmental resilience is just as critical as electrical performance.
Let’s take a closer look at what makes this resistor a dependable choice for demanding applications.
