Ceramic Safety Capacitors

Safety capacitors are available in ceramic disc and metalized film or paper.

Ceramic safety capacitors. For x type capacitors kemet offers sub class x1 devices. 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. 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. 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. 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. 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. Offering the benefits of simple pick and place assembly reduced board space required and lower.

Capacitors and schematics for antique tube radios. X1 y2 safety recognized ceramic disc capacitors are specifically made for high voltage ac alternating current applications. These line rated ac rated. Rfi is simply higher frequency emi figure 1.

Tecate group offers x and y safety capacitors in both ceramic smd styles and polypropylene film capacitors in a radial. Rfi safety rated x y ceramic capacitors manufactured by vishay a global leader for semiconductors and passive electronic components. X1y2 safety capacitors are versatile and can safely be used as both line bypass line to ground and accross the line capacitors. These safety capacitors are also known by other names including emi rfi suppression capacitors and ac line filter safety capacitors.
