In switching power supplies and electronic circuits, there is an electronic component called safety capacitor. The full name of the safety capacitor is the capacitor for suppressing the electromagnetic interference of the power supply. Safety capacitors will be rapidly discharged after the external power supply is disconnected, and there will be no inductance when touched by hand.
Not all capacitors are safety capacitors. Safety capacitors are capacitors that can only be sold after a series of safety certifications, and different countries have different standards for safety certification. Common safety certifications include CQC certification, KC certification, UL certification, VDE certification, and ENEC certification.
CQC certification: The full name is China Quality Certification Center. It is a certification body established with the approval of the competent department. It is an authoritative certification body that carried out certification work earlier in China and is a compulsory certification.
KC certification: KC certification is a unified mandatory certification in South Korea, and the KC certification mark represents that the product meets the product performance requirements of South Korea.
UL certification: short for Underwriter Laboratories Inc., it is a non-mandatory certification, which provides objective certification for the marketing publicity marked by the manufacturer for its products, such as product performance, quality, function and other claims.
VDE certification: The full name is the German Prufstelle Testing and Certification Institute, which directly participates in the formulation of German standards and is one of the certification bodies with a high reputation in the world.
ENEC certification: European standard electrical certification, is a certification program for electrical products initiated by the European Electrotechnical Standardization Committee and recognized by all parts of Europe.
Select a reliable manufacturer when purchasing capacitors can avoid a lot of unnecessary trouble. JYH HSU (or Dongguan Zhixu Electronics) not only has full models of ceramic capacitors with guaranteed quality, but also offers worry-free after-sales. JEC factories has passed ISO9001:2015 quality management system certification; JEC safety capacitors (X capacitors and Y capacitors) and varistors have passed the certification of various countries; JEC ceramic capacitors, film capacitors and super capacitors are in line with low carbon indicators.
