These porcelain and ceramic dielectric multilayer capacitor (MLC) chips are best suited for RF/ Microwave applications typically ranging from 10 MHz to 4.2 GHz. Characteristic is a fine grained, high density, high purity dielectric material impervious to moisture with heavy internal palladium electrodes. These characteristics lend well to applications requiring:

  1. high current carrying capabilities;
  2. high quality factors;
  3. very low equivalent series resistance;
  4. very high series resonance;
  5. excellent stability under stresses of changing voltage, frequency, time and temperature.
