Samsung capacitors have always been an electronic component that is very popular among manufacturers. For purchasing engineers, it is necessary to understand some details of the parameters to be considered when selecting Samsung capacitors.
What are the details of Samsung's capacitor selection?
All walks of life have their own auditing standards when making products. In the electronics industry, this is the product reference factor. The first choice for Samsung capacitor selection is the size of the capacitor package.
In order to facilitate the user's product design and the large-scale production of the chip capacitor manufacturing enterprise, Samsung Capacitor produces the size of the chip capacitor according to the industry standard according to the standard size.
Each standardized length, width and height dimension is represented by a package code. Capacity is also one of the parameters that cannot be ignored. 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. At the same time, for the error accuracy is also one of the important parameters that can not be ignored to select the capacitor.
The capacity error refers to the maximum deviation range allowed by the actual capacitance and the nominal capacitance. Commonly used capacitors have the same accuracy level as the 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 a small tolerance, while electrolytic capacitors have large errors, and they use different error levels.
In addition to this, the frequency characteristics can not be ignored. The nature of the electrical parameters of a capacitor as a function of the frequency of the electric field. In a capacitor operating under high frequency conditions, since the dielectric constant is smaller at a high frequency than at a low frequency, the capacitance is also reduced accordingly. Losses also increase with increasing frequency.
The factors that need to be considered for the selection of Samsung capacitors are introduced here. I hope that these parameters can help you choose the right type of capacitor accurately, which can guarantee the performance and service life of the capacitor.
