Q: How many types of safety capacitors are there?
A: Safety capacitors are divided into X type and Y type.
X capacitors mostly use polyester film capacitors with relatively large ripple currents. This type of capacitor has a relatively large volume, but its allowable instantaneous charging and discharging current is also large, and its internal resistance is correspondingly small.
The capacitance of the Y capacitor must be limited, so as to achieve the purpose of controlling the leakage current flowing through it as well as the impact on the EMC performance of the system under the rated frequency and rated voltage. GJB151 stipulates that the capacitance of Y capacitor should not be greater than 0.1uF.
Q: What’s the difference between Y1 and Y2 safety capacitors?
The rated voltage of Y1 is generally 400V-500V, and of Y2 is generally 300V-500V
Q: What is the tolerance of Y5V capacitor?
A: The tolerance of Y5V is M ±20%
Q: How long is the foot distance of Y capacitors?
A: It is usually 7.5mm long if there is no special requirement.
