How do you read a small capacitor?
Many capacitor manufacturers use a shorthand notation to indicate capacitance on small caps. If you have a capacitor that has nothing other than a three-digit number printed on it, the third digit represents the number of zeros to add to the end of the first two digits. The resulting number is the capacitance in pF.
How do I know what kind of capacitor I have?
Ceramic types of capacitors generally have a 3-digit code printed onto their body to identify their capacitance value in pico-farads. Generally the first two digits indicate the capacitors value and the third digit indicates the number of zero’s to be added.
How do I convert uF to nF?
Convert between uF, nF and pF using the Newark’s uF – nF- pF conversion chart below….Capacitor uF – nF – pF Conversion.
| uF/ MFD | nF | pF/ MMFD |
|---|---|---|
| 0.001uF / MFD | 1nF | 1000pF(MMFD) |
| 0.00082uF / MFD | 0.82nF | 820pF (MMFD) |
| 0.0008uF / MFD | 0.8nF | 800pF (MMFD) |
| 0.0007uF / MFD | 0.7nF | 700pF (MMFD) |
What does the uF mean on a capacitor?
micro farad
uF refers to the size of the capacitor. Capacitance is the charge that is necessary to raise the potential of a body one unit. A capacitance of 1 farad (f) requires 1 coulomb of electricity to raise its potential 1 volt (v). 1 micro farad (uF) = 0.0000001 F. Dannie Musser.
How do you identify capacitor terminals?
Capacitor Polarity Markings The ‘plus sign’ indication near the terminal indicates that the respective terminal is positive. So, it is considered as Anode. The other terminal has to be treated as Cathode. Capacitor polarity can be identified based on arrow representation.
How are capacitors letter coded?
The Capacitor Colour Code system was used for many years on unpolarised polyester and mica moulded capacitors. A three letter code consists of the two value digits and a multiplier much like the resistor colour codes in the resistors section. For example, the digits 471 = 47*10 = 470pF.
What is nF and uF?
Mica capacitors are usually expressed in terms of pF (micromicrofarads) (picofarads). Short forms for micromicrofarads include pF, mmfd, MMFD, MMF, uuF and PF. A pF is one-millionth of a uF. In between a pF and a uF is a nF which is one-one thousands of a uF.
