The third digit is the multiplier which is 1000.
Ceramic disc capacitor symbol.
It is consists of two number disc electrodes and placed in parallel.
The first two numbers describe the value of the capacitor and the third number is the number of zeros in the multiplier.
The first two significant digits represent the first two digits of the actual value which is 47.
They are very easy to decode to find the value.
Taking a look at this site today has enlightened me to not only letters on the caps but voltage codes as well.
An american company in the midst of the apollo program launched in 1961 pioneered the stacking of multiple discs to create a monolithic block.
On a larger capacitors there is sufficient space to mark the value the tolerance working voltage and often other data such as the ripple voltage.
Ceramic capacitor polarity and symbol.
Ceramic capacitors are also called disc capacitors a code of 3 digit is generally printed on the body of this type of capacitors to tell their capacitance in pico farads.
When the ceramic capacitor are layered multiple times it becomes mlcc.
The first two digits represent the value of the capacitor and the third digit represents the number of zeros to be added.
It is commonly used in the electronics application of electromagnetic interference.
Ceramic disc capacitor code label will normally consist of three numbers followed by a letter.
I have always been unaware of the markings on a disc ceramic capacitor such as j m and other symbols.
Depending on the shapes and sizes they are used as feed through capacitors electro magnetic interference supressers and even as power capacitors in transmittors.
Many larger capacitors like electrolytic capacitors disc ceramics and many film capacitors are large enough to have their markings printed on the case.
Click here for resistor colour code and smd resistor code ceramic disc capacitors have two to three digits code printed on them.
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.
When the first two numbers are multiplied with the multiplier the.
The early style of the ceramic disc capacitor could be more cheaply produced than the common ceramic tube capacitors in the 1950s and 1970s.
Ceramic disc capacitors have a capacitance value of about10pf to 100μf with a wide variety of voltage ratings between 16v to 15 kv and more.
It has small value capacitance and due to the high dielectric strength of the medium the voltage rating goes up to 1kv.
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.
To gain higher capacitances these devices can be made from multiple layers.
