Ceramic Safety Capacitors

For x type capacitors kemet offers sub class x1 devices.

Ceramic safety capacitors.

Offering the benefits of simple pick and place assembly reduced board space required and lower. Emi stands for electromagnetic interference and rfi stands for radio frequency interference. X1y2 safety capacitors are versatile and can safely be used as both line bypass line to ground and accross the line capacitors. Application voltages range from 400 to 760 vac nominal.

Capacitors and schematics for antique tube radios. Tecate group offers x and y safety capacitors in both ceramic smd styles and polypropylene film capacitors in a radial. For y type capacitors there are sub classes y1 y2 y3 and y4. Ac line rated ceramic disc capacitors class x1 400 vac class y4 125 vac.

Safety capacitors are high voltage circuit specific capacitors commonly rated at 250 vac. Safety capacitors are available in ceramic disc and metalized film or paper. This product is designed to handle high voltage impulses and transients as well as protect users from harm due to electrical shock. 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.

Rfi safety rated x y ceramic capacitors manufactured by vishay a global leader for semiconductors and passive electronic components. 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. These line rated ac rated.

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.
