Here are some tips for selecting Class Y capacitors:
1、Understand the application environment and requirements of the product. This includes working voltage, temperature range, noise suppression requirements, and more.
2、Choose the appropriate capacitor type based on the application environment and requirements. Generally, X-class capacitors are suitable for DC filtering, while Y-class capacitors are suitable for AC filtering and EMI suppression.
3、Select a suitable size and capacity based on the capacitor's rated voltage and capacitance value.
4、Pay attention to the standardization of the capacitor. Standardized capacitors typically have higher reliability and consistency.
5、Refer to the manufacturer"s data sheet to check whether the rated value and characteristic parameters of the capacitor meet the application requirements.
6、If possible, conduct practical testing and evaluation to ensure that the performance of the capacitor meets the requirements.
7、During the selection process, consider the price and availability of the capacitors as much as possible.
