Programmable Capacitor Chips

California Micro Devices’ PCC Series thin film programmable capacitor chip shares the same characteristics of CAMD’s CC Series thin film capacitors. Series PCC contains up to 5 capacitors with typical values of up to 1, 2, 4, 8 and 16pF capacitance. Binary ratios starting at 0.25 pF are also available. A common back metallization layer forms one plate of the capacitor; individual con tacts form the other plate; silicon dioxide dielectric features high Q and low positive, TCC over a wide temperature range. Series PCC is typically used in circuits involving active filters, such as - Chebyshev or Butterworth filter (multiple feedback design) for high pass, low pass, or band pass applications.
