The C1005X7R1H102K050BA is a ceramic chip capacitor manufactured by TDK Corporation. It is part of the X7R series and has a capacitance of 0.1µF or 100nF. It has a dielectric of X7R, a rated voltage of 10V, a tolerance of ±10%, an operating temperature range from -55°C to 125°C, an ESR of 0.17O, and a size of 0402 (10.0mm x 5.0mm). The X7R dielectric is a non-stable, temperature-compensated dielectric material which is suitable for AC line-level equipment, whereas the C0G dielectric – also known as “NP0” – is a more stable, stable material suitable for DC applications. Both C0G and X7R have low inherent losses and high dielectric breakdown strength.
