Capacitors are rated according to how near to their actual values they are compared to the rated nominal capacitance with coloured bands or letters used to indicated their actual tolerance. The most common tolerance variation for capacitors is 5% or 10% but some plastic capacitors are rated as low as ±1%.
Hence, quality of capacitors is process. 1. Problems are identified and prioritized the major cause effectively. 2. Establishment of the needs of various practical applications 3. Improve the process/product by apply the efforts in right direction. eliminate the categories of defects. P areto diagram and
The Q-factor or the quality factor of a capacitor at the operating frequency ω is defined as the ratio of the reactance of the capacitor to its series resistance. Q = (X C / R). It is a dimensionless quantity. D-Factor – The dissipation factor of a capacitor is the power loss when AC is applied through the capacitor.
A capacitor is measured by the size of its capacitance. A capacitance is the electric capacity of a capacitor, i.e. the amount of electrically charged carriers it can store. ɛ r . The relative dielectric constant can have values between ɛ r = 1 (air) and ɛ r ~ 10,000 (special ceramic materials).
The capacitance of a capacitor can change value with the circuit frequency (Hz) y with the ambient temperature. Smaller ceramic capacitors can have a nominal value as low as one pico-Farad, ( 1pF ) while larger electrolytic’s can have a nominal capacitance value of up to one Farad, ( 1F ).
Smaller ceramic capacitors can have a nominal value as low as one pico-Farad, ( 1pF ) while larger electrolytic’s can have a nominal capacitance value of up to one Farad, ( 1F ). All capacitors have a tolerance rating that can range from -20% to as high as +80% for aluminium electrolytic’s affecting its actual or real value.
