Solid Red Ceramic Y Capacitor

You can quickly identify a through hole ceramic capacitor by looking for the small yellow or red bulbs with two terminals sticking out of them.

Solid red ceramic y capacitor. Of these x2 and y2 capacitors find the most widespread application in common household appliances. One specific use of capacitors is in power line filtering in many appliances and electronic devices. These capacitors were used in devices for applications that required the lowest possible esr or highest possible ripple current. The video explores the method to determine the values of a ceramic capacitor with an example.

Let us see an example of ceramic or disc capacitor for calculating the color code on it. But it is difficult to identify the values in the case of old capacitors. The most common classes available commercially are x1 x2 y1 and y2 which are impulse tested to 4 kv 2 5 kv 8 kv and 5 kv respectively. Disc ceramic capacitor.

The first al e caps to use the charge transfer salt ttf tcnq as a solid organic electrolyte was the os con series offered in 1983 from sanyo these were wound cylindrical capacitors with 10x increased electrolyte conductivity compared with mno 2. Subclass x1 x2 and x3 and subclass y1 y2 y3 and y4. Unlike their electrolytic counterparts ceramic capacitors hold a smaller charge but also leak less current. Automotive grade ac line rated ceramic disc capacitors class x1 760 vac class y1 500 vac.

Sometimes figures such as 10n will be seen and this indicates a 10nf capacitor. 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. Manufacturers produce x capacitors in classes x1 to x3 and y capacitors in classes y1 to y4. A variety of schemes may be used.

Often the value may be given in picofarads. Capacitors used in these applications are categorized as being either class x or class y and then rated by their tested voltage such as x1 or y2. These class designations refer to a capacitor s safety rating and application. 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.

These colour codes are used from many years for non polarized capacitors like disc and ceramic capacitors.
