When purchasing Samsung capacitors, the package size of the capacitor is the first to be considered. In order to ensure the user's product design and the large-scale production of the chip capacitor manufacturing enterprise, Samsung capacitors produce standard size chip capacitors according to industry standards, a package number. Represents a standard size, length, width and height.
The parameter that cannot be ignored is the capacity. The electrostatic capacity, that is, the storage charge capacity C of the capacitor, is the main indicator of the capacitance. Commonly used units are pf, nf and uf, and the conversion formula is: 1uF=1000nF=1000 000pF. Error accuracy is also one of the important parameters that can not be ignored in selecting a capacitor. The capacity error refers to the maximum allowable deviation range of the actual capacitance and the nominal capacitance. Commonly used capacitor accuracy levels are the same as resistors, expressed in letters, which are: 0.5% for D; ±1% for F, 5% for ±J, ±10% for K, and ±20% for M. High-precision precision capacitors have small tolerances, and electrolytic capacitors have large errors, and they use different error levels.
The frequency characteristics are also not negligible, and the electrical parameters of the capacitor vary with the frequency of the electric field. Capacitors operating at high frequency conditions have a lower capacitance as the dielectric parameters are lower at low frequencies than at low frequencies. Losses also increase with increasing frequency.
These parameters can help you choose the right capacitor type accurately, which can guarantee the performance and service life of the capacitor.
