Solid Red Disc Ceramic Y Capacitor

Solid red disc ceramic y capacitor. The first two numbers describe the value of the capacitor and the third number is the number of zeros in the multiplier. A variety of schemes may be used. Sometimes figures such as 10n will be seen and this indicates a 10nf capacitor. The first two significant digits represent the first two digits of the actual value which is 47.

The smallest capacitors made from ceramic film or tantalum use units of picofarads pf equal to 10 12 farads. The capacitor on the left is of a ceramic disc type capacitor that has the code 473j printed onto its body. They are very easy to decode to find the value. The third digit is the multiplier which is 1000.

Often the value may be given in picofarads. The letter j signifies the tolerance of 5. 47pf 1 000 3 zero s 47 000 pf 47nf or 0 047uf the j indicates a tolerance of 5. Click here for resistor colour code and smd resistor code ceramic disc capacitors have two to three digits code printed on them.

When the ceramic capacitor are layered multiple times it becomes mlcc. Similarly n51 indicates a 0 51nf or 510 pf capacitor etc. When the first two numbers are multiplied with the multiplier the. Made of ceramic material as the dielectric and metal as the electrodes ceramic capacitors come in a variety of shapes and sizes.

Smd ceramic capacitor codes. The first ceramic capacitor was disc shaped and now it is available in different shapes and sizes. Then the 4 1 st digit the 7 2 nd digit the 3 is the multiplier in pico farads pf and the letter j is the tolerance and this translates to. Depending on the shapes and sizes they are used as feed through capacitors electro magnetic interference supressers and even as power capacitors in transmittors.

They are generally less expensive than other capacitors and carry lower capacitances couple of µf max which makes them used often during low capacitance requirements in noise harmonics filtering and suppression applications. 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. Then by just using numbers and letters as codes. Multi layer ceramic capacitor mlcc mlccs are manufactured by accurately mixing finely ground granules of paraelectric and ferroelectric materials and alternatively layering the mix with metal contacts.

Surface mount capacitors are often very small and do not have the space for markings. Ceramic disc capacitors have a capacitance value of 10pf to 100μf with a wide variety of voltage ratings between 16 volts to 15 kv and more.
