Film Capacitor Code

While in case the capacitor is of aluminium electrolytes microfarads is used to denote the capacitors value. Capacitance is measured in farads.

470 is the code for 47pf you need a code 471 for a 470pf capacitor.

Film capacitor code. This is vacuum deposited onto the plastic film. My leaving a small area free of metallisation at either end. In case small values with decimal points needs to be represented.

Large capacitors usually have their value printed plainly on them such as 10uf ten micro farads. This capacitor marking code uses three characters. 47pf 1000 3 zeros 47000 pf.

How to read capacitor codes. The thin metal layer is typically only 002 to 01um thick. The capacitor on the left is of a ceramic disc type capacitor that has the code 473j printed onto its body.

In case the capacitors are tantalum ceramic or film capacitors picofarads is used to denote the capacitors value. 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. It bears many similarities to the numeric code system adopted for some surface mount resistors.

2a is 100vdc rating according to the eia electronic industries alliance standard. Basic structure of the ordering code. One farad is a huge capacitor so most normal capacitors have values in the micro farad 0000001f 1uf 10 6 or pico farad 0000000000001f 1pf 10 12 range.

The value of the capacitor is denoted in picofarads for ceramic film and tantalum capacitors but for aluminium electrolytic capacitors the value is denoted in microfarads. In this type of film capacitor the plastic film has a very thin layer of metallisation deposited onto the film. Digit meaning 1 b passive components 2 3 32 81 metallized film capacitors emi suppression capacitors emi suppression capacitors 4.

The first two figures refer to the significant figures of the capacitor value and the third one acts as a multiplier. Codes of polyester film and metallized film capacitor if a capacitor is marked with 2a474j the capacitance is decoded as described above the two first signs is the voltage rating and can be decoded from table given below here. Disc capacitors are usually ceramic and for a 5 mm wide capacitor 500v rating sounds reasonable but do check manufacturers datasheet to be sure.

Tor using a plain text description ie. 6 type block 1 is termed the type number 7 revision status s a special type.
