Description

Benefits of Knowles Precision Devices Panel Mount EMI Filters

  • Use of Stable X7R and C0G/NP0 ceramics - no Z5U/Y5V
  • High capacitance values, high voltage
  • High frequency performance to greater than 10GHz

When choosing a filter, it is important to be aware of the different performance characteristics that may be available from different categories of ceramic materials employed in their capacitors. Generally, stability of dielectric constant (and therefore filter capacitance value), with respect to some operational and environmental parameters, deteriorates with increasing dielectric constant. Specific factors which affect dielectric constant are temperature, voltage, frequency and time (ageing).  The three main classifications of ceramic dielectric employed in the manufacture of EMI filters are generally referred to as ultra stable (C0G/NP0), stable (X7R) and general purpose (Z5U, Y5V or X7W).
