Ceramic Y Capacitors

In a multilayer configuration they display high capacitance values and various voltage ratings over a wide temperature range.

Ceramic y capacitors.

A ceramic capacitor is a fixed value capacitor where the ceramic material acts as the. Multiple styles are available such as mlcc chips leaded capacitors stacked capacitors and capacitors that utilize unique geometries. 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. For y capacitors ceramic types are less expensive than metallised film but unstable over time and temperature and less mechanically stable.

X capacitors effectively absorb symmetrical balanced or differential interference. 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. Subclass x1 x2 and x3 and subclass y1 y2 y3 and y4. Kemet s extensive portfolio of capacitors covers 96 of all dielectric options available that find usage in automotive industrial telecommunications defense and consumer electronics.

Ceramic capacitors exhibit low parasitics and excellent emi filtering capabilities. Capacitors ship same day. Ac line rated ceramic disc capacitors class x1 400 vac class y4 125 vac. Generally x capacitors work for across the line applications and y capacitors work for line bypasses or line to ground applications.
