Plastic encapsulated Y1 capacitors and plastic encapsulated Y2 capacitors are common electronic components that play different roles in circuits. The following will provide a detailed introduction to their biggest differences and characteristics.
Different usage scenarios and parameters
The plastic encapsulated Y1 capacitor is mainly used to suppress common mode interference and differential mode interference, and it has the characteristics of high stability and low leakage current. Its capacity is usually between 1000pF and 10 μ Between F, the withstand voltage is usually between 63V and 2000V. It is mainly used for transmission equipment and systems in fields such as communication, data processing, and power, especially suitable for circuits in harsh environments such as high temperature, high humidity, and high frequency.
The plastic encapsulated Y2 capacitor is a general-purpose capacitor mainly used in circuits such as filtering, coupling, and bypass. Its capacity is usually below 1000pF, and its withstand voltage is usually between 63V and 500V. It is suitable for various electronic devices, including household appliances, industrial control, automotive electronics, medical devices, and other fields.
Different security levels
The safety level of the molded Y1 capacitor is relatively high, which meets the safety standards of Y1 capacitors and has high safety performance. The safety level of the plastic encapsulated Y2 capacitor is relatively low, and it meets the safety standards of Y2 capacitors. Compared to Y1 capacitors, its safety performance is slightly inferior.
Different media
The dielectric of the molded Y1 capacitor is made of polyester film, which has the characteristics of high stability and low leakage current. The dielectric of the plastic encapsulated Y2 capacitor uses polypropylene film, which has slightly inferior performance compared to polyester film.
Different temperature ranges
The temperature range of the molded Y1 capacitor is usually between -55 ℃ and+125 ℃, which can adapt to a wide temperature range. The temperature range of plastic encapsulated Y2 capacitors is usually between -40 ℃ and+85 ℃, which is relatively narrow compared to Y1 capacitors.
In summary, the biggest difference between plastic encapsulated Y1 capacitors and plastic encapsulated Y2 capacitors lies in their usage, parameters, safety level, medium, and temperature range. Molded Y1 capacitors are mainly used to suppress common mode interference and differential mode interference, with high stability and low leakage current, suitable for circuits in harsh environments such as high temperature, high humidity, and high frequency; The plastic encapsulated Y2 capacitor is a general-purpose capacitor mainly used in circuits such as filtering, coupling, and bypass, suitable for various electronic devices. In practical applications, it is necessary to select appropriate electronic components based on the specific needs of the circuit.
