... These can be used for CFB since it is internally limited to approximately ±3V. The CDC HC55185CIM capacitor may be either polarized or non polarized. HC55185DIM HC55185ECM Parametric Improvements The most significant parametric improvement of the HC55185 is reduction in Idle Channel Noise. This improvement was accomplished by redistributing gains in the impedance matching loop ...
