**What is the value of capacitor 104?**

In This Article

Marking | Capacitance (pF) | Capacitance (ìF) |
---|---|---|

473 | 47,000 pF | 0.047 ìF |

104 | 100,000 pF | 0.1 ìF |

224 | 220,000 pF | 0.22 ìF |

474 | 470,000 pF | 0.47 ìF |

### What is JW in capacitor?

More correctly, we say the reactance Xc = 1/jwc or -j/wc. j is the square root of negative one, and 1/j = -j. j is the imaginary number, used in this case to sort out reactance and impedance from pure resistance. This is because the reactance of a capacitor is a leading reactance.

### What does 223 mean on a capacitor?

Marking | Capacitance (pF) | Capacitance (ìF) |
---|---|---|

222 | 2,200 pF | 0.0022 ìF |

472 | 4,700 pF | 0.0047 ìF |

103 | 10,000 pF | 0.01 ìF |

223 | 22,000 pF | 0.022 ìF |

**What does 474j mean on a capacitor?**

Looking at our capacitor we will see its marked 474J, this should be read as follows, 47 times the value that can be found in Table 1 corresponding to the 3rd number, in this case 10000. 47 * 10000 = 470000 pF = 470 nF = 0.47 uF with the J meaning a 5% tolerance. A second letter will be a temperature coefficient if its present.

## What is the voltage rating for a 47pf capacitor?

470 is the code for 47pF, you need a code 471 for a 470pF capacitor. Disc capacitors are usually ceramic and for a 5 mm wide capacitor, 500V rating sounds reasonable, but do check manufacturers datasheet to be sure.

## What is the decoding code for capacitor?

Decoding capacitor codes pico-farad (pF) nano-farad (nF) mikro-farad (mF, uF or mfd) Capacitor code 1 pF 0.001 nF 0.000001 uF 010 1.5 pF 0.0015 nF 0.0000015 uF 1R5 2.2 pF 0.0022 nF 0.0000022 uF 2R2 3.3 pF 0.0033 nF 0.0000033 uF 3R3

**What is the meaning of SMD ceramic capacitor code N51?**

Sometimes figures such as 10n will be seen and this indicates a 10nF capacitor. Similarly n51 indicates a 0.51nF, or 510 pF capacitor, etc . . SMD ceramic capacitor codes: Surface mount capacitors are often very small and do not have the space for markings.
