Before editing, the article published in the Y capacitor voltage specifications has been eager to answer many readers, including one of the users asked "JY561K2FY5P" What does it mean? In fact, a series of numbers for the person who started to contact the capacitor is a code or other complex The thing is, in fact, not so, the gradual decomposition of the symbol letter is actually a number of specification constants, I believe we will understand a little bit of understanding.
JY is a Y2 capacitor, a safety capacitor, and the other is JD, which represents a Y1 capacitor.
561 is 560 PF. In the International System of Units, the unit of capacitance is farad, or abbreviation, and the symbol is F. Since farads are too large, the commonly used capacitor units are millifarads (mF), microfarads (μF), and nanofarads. (nF) and pF (pF), the conversion relationship is:
The commonly used 1 microfarad (μF) = 1000 nanofarads (nF) = 1,000,000 picofarads (pF).
K is the deviation +-10%, K.M.J represents the capacitance deviation
K stands for positive and negative 10% of capacity deviation
M represents plus or minus 20% deviation
J represents 5% of positive and negative deviation
2F is an abbreviation of 300V withstanding voltage, Safety Capability Safety Rating Insulation Type Rated Voltage Range
Y1 double insulation or reinforced insulation ≥ 250V
Y2 Basic insulation or additional insulation ≥150V ≤300V
Y5P represents the material, Y5P has the best temperature compensation performance, and the capacitance value in the full temperature range is ±10%.
Y5U has no compensation for temperature changes, and the capacitance range over the full temperature range is +22%/-56%.
Y5V has no compensation for temperature changes, and the capacitance range over the full temperature range is +30%/-82%.
