6 FAQs about [Capacitor Usage Regulations]
What is the capacitance requirement for a safety capacitor?
The capacitance requirement for this connection is that the safety capacitor’s value must be much larger than the parasitic winding capacitance. This usually means a Class Y capacitor with 1 nF to 1 uF will work, depending on the frequency range required to bypass to the primary side of the system.
What is a safety capacitor?
One of these techniques is the use of so-called safety capacitors, also known as Class X and Class Y capacitors. These capacitors are not special or unique. Just like a decoupling capacitor, the term “safety” refers to the function and placement of the capacitor, not to a specific type of capacitor.
What is a power capacitor?
describe the state of technology which must as a rule be adhered to in all relevant contracts for goods and services. II. General safety rules Since power capacitors are electrical energy storage devices, they must always be handled with caution.
Where are safety capacitors located in a power supply?
In isolated power supplies, safety capacitors are placed primarily in two locations: In the first case, Class X and Class y capacitors are placed in EMI filter circuits on the front end of a power supply.
Should a capacitor test be based on a standard?
Even if the test based on the capacitor standard is passed, this does not ensure comprehensive protection against all pos-sible overloading. Currently, a number of customers are requesting special tests on unprotected capacitors with extreme overvoltages and temperatures to prove safe capacitor per-formance.
What type of safety capacitor should I use for a PCB?
Normally a Class Y safety capacitor is recommended for this, but a Class X safety capacitor could also be used. The idea here is that the connection allows high-frequency noise currents to pass between the grounds as needed rather than allowing them to radiate their energy away from the PCB. The world’s most trusted PCB design system.
