mica capacitor การใช้

• Rubens idea adopted the stacked construction of a silver mica capacitor.
• On the receiver side smaller mica capacitors were used for resonant circuits.
• They are sometimes informally referred to as mica capacitors.
• On the receiver side, the smaller mica capacitors were used for resonant circuits.
• The silver mica capacitors are also now becoming obsolete because of the high price of mica.
• Therefore, these ceramic capacitors only could replace the commonly used mica capacitors for applications where stability was less important.
• Smaller dimensions, as compared to the mica capacitors, lower production costs and independence from mica availability accelerated their acceptance.
• Any modern reference to mica capacitors can be assumed to mean these, unless pre-war equipment is being discussed.
• The Rheostatic Machine used a bank of mica capacitors, a clever rotating commutator and a series of contacts to alternately charge a bank of capacitors in parallel ( from a high-voltage battery source ) and then connect the capacitors in series.
• Paraelectric titanium dioxide ( rutile ) was used as the first ceramic dielectric because it had a linear temperature dependence of capacitance for temperature compensation of resonant circuits and can replace mica capacitors . 1926 these ceramic capacitors were produced in small quantities with increasing quantities in the 1940s.
