TOPO GROUP CO., LTD >  Ceramic Capacitor

Ceramic Capacitor

SMD Multilayer Ceramic Capacitor




Feature

1. Stringgent dimensional tolerance allow highly reliable, highly speed automaric chip placement on PCBs.

2. Terminations are plated with Ni and solder, suited to flow and reflow soldering.

3. High insulation resistance and high reliabibty.

4. These capacitors have temperature characteristics ranging from COG to Y5V, applied to general electronic equipment, and instrument panel house electronic appliance.

 

Capacitor Selection

The  choice  of  dielectric  is  largely  determined  by  the  temperature  stability  required:

1. NPO(COG) -- Ultra stable Class I dielectric, with predictable change of electrical properties on temperature, voltage, frequency and time.  Used in circuits requiring stable performance.

2. X7R -- Stable Class II dielectric, with predictable change of properties with temperature, voltage, frequency and time. Used as blocking,  coupling, by-passing and frequency discriminating elements.This dielectric is ferroelectric and offers higher capacitance ranges than  class I.

3. Y5V(Z5U) --  General purpose Class II d ielectric with highest d ielectric constant and greater variation of properties  with temperature and test  conditions. Very high capacitance per unit volume and suited for application as well as filtering, transient suppression blocking, and charge storage application.
