Additional Details

The 0402B101K500CT has a capacitance value of 100pF (picofarads) with a tolerance of ±10%. The voltage rating is 50V. The dielectric material is typically a stable ceramic formulation such as X7R or NP0/COG, depending on the specific requirements of the application. X7R provides good capacitance stability over temperature, while NP0/COG offers even higher stability but typically at a lower capacitance value. These capacitors are designed to be reflow soldered onto printed circuit boards using standard SMT assembly techniques.

Its small size and stable electrical characteristics make it a popular choice for a wide range of electronic devices where space is limited and reliable performance is essential.
