Ceramic Safety Capacitors

These line rated ac rated.

Ceramic safety capacitors.

Rfi safety rated x y ceramic capacitors manufactured by vishay a global leader for semiconductors and passive electronic components. Offering the benefits of simple pick and place assembly reduced board space required and lower. For x type capacitors kemet offers sub class x1 devices. This product is designed to handle high voltage impulses and transients as well as protect users from harm due to electrical shock.

An example of a class y capacitor. Rfi is simply higher frequency emi figure 1. Ac line rated ceramic disc capacitors class x1 400 vac class y4 125 vac. X1 y2 safety recognized ceramic disc capacitors are specifically made for high voltage ac alternating current applications.

Capacitors and schematics for antique tube radios. Safety certified capacitors syfer technology s safety certified capacitors comply with international ul and tüv specifications to offer designers the option of using a surface mount ceramic multilayer capacitor to replace leaded film types. Tecate group offers x and y safety capacitors in both ceramic smd styles and polypropylene film capacitors in a radial. Safety capacitors are available in ceramic disc and metalized film or paper.

These safety capacitors are also known by other names including emi rfi suppression capacitors and ac line filter safety capacitors. Emi stands for electromagnetic interference and rfi stands for radio frequency interference. Capacitor array c0g dielectric 10 200 vdc capacitor array x7r dielectric 10 200 vdc telecom tip and ring x7r dielectric 250 vdc konnekt u2j for high efficiency high density power applications x7r with konnekt technology 25 1 500 vdc 250 vac non safety rated ac capacitors can series. A ceramic capacitor is a fixed value capacitor where the ceramic material acts as the dielectric it is constructed of two or more alternating layers of ceramic and a metal layer acting as the electrodes the composition of the ceramic material defines the electrical behavior and therefore applications.

The film type are made of self healing metalized polyester polypropylene or paper and usually come in a box style casing as the capacitor is encased is a flame retardant or flame proof case. Safety capacitors are grouped into a number of different sub classes. Safety capacitors are high voltage circuit specific capacitors commonly rated at 250 vac. For x type capacitors there are sub classes x1 x2 and x3.

For y type capacitors there are sub classes y1 y2 y3 and y4.
