What are X and Y rated capacitors?
IC's ( BQ76PL455A-Q1 or BQ76PL536A-Q1). Safety Standards classify X and Y rated capacitors to different classes according to their rated voltage and peak impulse voltage they can safely withstand. Peak Impulse voltage refers to the sudden rise in voltage that may be caused by lightning or other power surges.
What are Class X and Y capacitors used for?
Class X and Y capacitors are commonly used in electric vehicles to suppress harmful EMI noises. EMI suppression capacitors are used in a wide range of electronic circuits to suppress noise from various sources. These capacitors are commonly used in power supply systems to attenuate and block voltage spikes.
What is a Class X capacitor?
Class X capacitors are specially designed for across-the-line applications while class Y components are optimized for line-to-ground applications. In the electric drive system, these capacitors are used to attenuate and block unwanted signals.
What is a noise suppression capacitor?
In a typical power supply system, noise suppression capacitors are exposed to both AC voltages as well as voltage transient pulses from other sources. These capacitors are expected to withstand spikes and surges that can be as high as 5kV.
Are Y1 and Y3 capacitors the same?
Just like class X capacitors, these components are further subdivided into subclasses depending on their voltage ratings. Y1 capacitors have the highest voltage rating while Y3 components have the lowest. As compared to class X capacitors, these line-to-ground capacitors have lower capacitance values.
