Ceramic Y Capacitors

Ac line rated ceramic disc capacitors class x1 400 vac class y4 125 vac.

Ceramic y capacitors. Capacitors ship same day. X capacitors effectively absorb symmetrical balanced or differential interference. For y capacitors ceramic types are less expensive than metallised film but unstable over time and temperature and less mechanically stable. Capacitors ceramic capacitors are in stock at digikey.

Because class x and class y capacitors must be connected directly to ac lines line to neutral or line to ground in order for them to perform their emi and rfi filtering functions they must be rated and certified as safety capacitors both class x and class y capacitors have subclasses. Kemet s extensive portfolio of capacitors covers 96 of all dielectric options available that find usage in automotive industrial telecommunications defense and consumer electronics. Subclass x1 x2 and x3 and subclass y1 y2 y3 and y4. Y capacitors are connected in a line bypass between a line phase and a point of zero potential to absorb asymmetrical unbalanced or common mode.

A y capacitor can take the place of an x capacitor in an across the line application only when absolutely necessary though this is highly uneconomical. Multiple styles are available such as mlcc chips leaded capacitors stacked capacitors and capacitors that utilize unique geometries. Ceramic capacitors exhibit low parasitics and excellent emi filtering capabilities. A ceramic capacitor is a fixed value capacitor where the ceramic material acts as the.
