Safety Capacitor JY472M Introduction

JY472M safety capacitor is a main component used in the circuit of changing DC switching power during the task cycle, and it can reduce the electromagnetic interference of the home appliance, electronic equipment and the rest of the disturbance source.

So what does JY472M mean in the safety capacitor? In fact, JY capacitor is the English abbreviation of Y2 type of safety capacitor, 472 is 4700PF, pf is the capacitance capacity, the specification of safety capacitor JY is M, M is the meaning of error value, but also accuracy, M capacitor partial vector is positive and negative 20%, the rest, assuming K, that is, the K-capacitor bias vector is plus or minus 10%. The nominal voltage of the JY472M capacitor is AC250V and AC300V. It can reach 3000VAC after the withstand voltage test. In fact, the standard specification is also 300VAC, because the voltage increase of 20% is more guaranteed.

Sometimes it is confusing that in Y2, M has sub-materials Y5V and Y5U, and K is Y5P. Y5U is not compensated for temperature conversion, and the capacitance value within the temperature limit is changed from +22% to -56%. Y5V is not compensated for temperature conversion, and the capacitance value within the temperature limit is changed from +30% to -80%. In the safety Y capacitor, the capacitance change of Y5U is smaller than that of Y5V, so the safety capacitor with Y5U characteristics is better, but the price will be more expensive than Y5V.
