Safety capacitors are one of the electronic components widely used in electronic equipment, and are widely used in DC blocking, coupling, bypass, filtering, tuning loops, energy conversion, control circuits, etc.

The safety capacitor itself is printed with font numbers, and these font numbers are silk screen, so what does the silk screen on the safety capacitor mean? In fact, these silk screens are the parameters and identification of safety capacitors, just like the production items themselves have production dates, production marks, etc., safety capacitors themselves also have silk screens.

The desired information can be obtained through the parameters and marks on the silk screen of the safety capacitor, and the appropriate safety capacitor can be selected for the appropriate occasion through the parameters and marks on the silk screen of the safety capacitor. The editor uses the product safety capacitor of Zhixu Electronics as an example to show you the silk screen logo on the safety capacitor.

Let's understand the silk screen parameters of X2 safety capacitors:

Safety capacitor

(1) JEC: is the brand trademark of capacitors, the brand is Zhixu JEC

(2) 0.01μF: It is the English symbol of the capacity of the capacitor, and the Chinese is called microfarad, which is the unit of the capacitor size. The size of the X2 safety capacitor of Zhixu JEC is 0.01μF

(3) K: is the capacitance error of the capacitor, and the X2 safety capacitance error of Zhixu JEC is ±10%

(4) MPX: represents the model of the capacitor, and the X2 safety capacitor model of Zhixu JEC is MPX

(5) X2: Capacitor category, the capacitor is X2 safety capacitor

(6) IEC60384-14: It is the standard for electromagnetic interference suppression capacitors. Zhixu JEC's X2 safety capacitors meet the standards for electromagnetic interference suppression capacitors.

(7) 40/110/56/B: represents the climate category, the lower limit temperature is -40°C, the upper limit temperature is 110°C, the duration of the steady-state damp heat test is 56 days, the flame retardant grade is B, and the X2 safety capacitor of Zhixu JEC passed the test

(8) 250/275/300/305/310VAC: the rated voltage used by Zhixu JEC's X2 safety capacitor
