Introduction
GMC SERIES
Multilayer Surface Mount Ceramic Capacitors are constructed by screen printing alternative layers of internal metallic electrodes onto ceramic dielectric materials and firing into a concrete monolithic body, then completed by application of metal end terminations which are fired to assure permanent bonding with the individual internal electrodes. Multilayer ceramic capacitors have various features such as large capacitance values in small sizes and excellent high frequency characteristics. Moreover, chip capacitors can be used on surface mount assembly equipment. Our fully integrated manufacturing and total quality control systems ensure unprecedented high standards of quality and reliability.
Chip Capacitor Selection
Dielectric Type
The choice of dielectric is largely determined by the temperature stability required.
Selection of the most suitable capacitor for any application is based on the following:
COG (NPO)
Capacitance change with temperature is 0-30ppm/°C which is less than -0.3%°C from -55°C to +125°C. Typical capacitance change with life is less than -0.1% for NPOs, one-fifth that shown by most other dielectrics. NPO formulations show no aging characteristics.
X7R/X5R
Its temperature variation of capacitance is within ±15% from -55°C to +125°C (-55°C to +85°C for X5R). The capacitance change is non-linear.
Z5U
Despite their capacitance instability, Z5U formulatio...
