Additional Details

The GRM155B31C105KA12D utilizes a B dielectric material, which offers a good balance between capacitance and stability. The 0402 case size makes it ideal for use in compact electronic devices where board space is limited. This capacitor is suitable for bypass and decoupling applications, helping to filter noise and stabilize voltage levels in electronic circuits. The 'K' in the part number indicates a ±10% capacitance tolerance. The termination is typically made of nickel barrier with tin plating to ensure excellent solderability. The 16V rated voltage allows it to be used in various low-voltage applications. The 'A12D' suffix likely pertains to Murata's internal control code and tape reel packaging. These MLCCs are manufactured using precise layering and firing techniques to achieve the desired electrical characteristics and mechanical strength. This part is optimized for reflow soldering processes, commonly used in modern electronic assembly lines. Its small size and robust construction make it a reliable choice for a wide range of electronic applications, particularly in portable electronic devices.
