PCC

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 contacts from 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.

There are some electrical specifications about PCC. Operating temperature range is -55 to 125. Peak voltage(@25) is 1.5 X working voltage.Dissipation factor(@1KHz,1V,25) is 0.1% max. Q(@1 MHz,50 MV, 25) is 1000 min. Temperature coefficient of capacitance is ±50 ppm/.

Well, this is a simple introduction to this type of product, if you want to know more about PCC, please pay more attention to our web. Thanks for your attention!
