How do I identify a surface mount capacitor?
Often a SMD device will have it’s value encoded in the form of numbers and letters, made by a laser marking system. 4.7U indicates a 4.7 microfarad part while 3.3 P is the marking for a 3.3 picofarad capacitor.
What does 103 written on a capacitor mean?
Capacitors will have a number on them like 103, 104, 224 . The last number represents the number of zeroes. All values are in picofarads. For example: 103 becomes 10 + 000 (3 zeroes) pF = 10000 pF = 10 nF. For example: 224 becomes 22 + 0000 (4 zeroes) pF = 220000 pF = 220 nF = .22 uF.
How many pF is 100nF?
100000pF
Capacitor uF – nF – pF Conversion
| uF/ MFD | nF | pF/ MMFD |
|---|---|---|
| 0.1uF / MFD | 100nF | 100000pF (MMFD) |
| 0.082uF / MFD | 82nF | 82000pF (MMFD) |
| 0.08uF / MFD | 80nF | 80000pF (MMFD) |
| 0.07uF / MFD | 70nF | 70000pF (MMFD) |
Is it OK to use a higher UF capacitor?
Small increases may be safe, large ones not. You can almost always replace a capacitor with one of a higher voltage. This is the limiting factor of a capacitor due to dielectric breakdown voltages that the manufacturer chose. Varying capacitance gets a little trickier.
What is the tolerance capacitor marking code for an EIA capacitor?
EIA Tolerance Capacitor Marking Code Letter code Tolerance Z +80%, -20% – this is used with electroly M ±20% K ±10%
What is the value of 100000pf on a capacitor?
The first two figures give 10 the third figure’4′ gives 0000 and the last ‘k’ = 10%. Therefore, the capacitor is 10,0000pF, 10%. This is normally expressed as 0.0luF or l00nF – capacitors with a value below 0.001uF are expressed in Picofarads.
What does the tolerance of a capacitor mean?
Tolerance indicates how close the capacitors marked value is to its actual value A tolerance can be marked several ways, numerically, as a code. Consisting of a single letter or a colour band or dot. Tolerance code letters are usually placed immediately after the value.
What does the IEC code on a capacitor mean?
However there are a number of capacitors manufacturers who use the ‘IEC’ code. the ‘IEC’ code is a numerical code that works in a similar way to the resistor colour code: two figures followed by a multiplier. Quite often there is a single letter, indicating tolerance.
