Class X2 and Y2 are the most commonly used safety-certified capacitors. Whereas X2 and Y2 caps are appropriate for household applications, X1 and Y1 safety capacitors are used in industrial settings. Y Capacitors: Also known as "line to ground capacitors" (line bypass.) Y capacitors are used in applications where failure of the capacitor could lead to the danger of electrical shock to the user, if the ground connection is lost.

JYA Y1 and Y2 Safety Standard Recognized Capacitors Typical applications:
Line disturbances suppression, Motors and motor controls, Relays, Switching power supplies, Inverters, Line-to-line (Class X) filtering, Line-to-ground (Class Y) filtering, Antenna coupling, Primary and secondary coupling, Network and security protection, audio visual product,, Home Appliance, new energy, Industry automation, LED

Super capacitors are ideal when a quick charge is needed to fill a short-term power need. They  are widely used in solar power applications, battery back-up applications, battery applications, flash-light applications, etc.

Super capacitors have also made critical inroads into electric powertrains. The virtue of ultra-rapid charging during regenerative braking and delivery of high current on acceleration makes the super capacitor ideal as a peak-load enhancer for hybrid vehicles as well as for fuel cell applications.
