What is the capacitance value of a film capacitor?

Capacitance Value: T he capacitance value of a film capacitor is expressed in units of farads (F) or microfarads (μF). Typically, the capacitance value is marked directly on the capacitor body, often using alphanumeric codes. For example, a marking of “473” indicates a capacitance value of 47,000 pF, which is equivalent to 0.047 μF.

How do you read a film capacitor?

How to Read Film Capacitor Values Film capacitors have their capacitance value directly printed on them in picofarads (pF), nanofarads (nF), or microfarads (μF). For example, “473” means 47,000 pF or 47 nF, and “0.1μ” means 0.1 μF.

How do you find the capacitance of a Mylar film capacitor?

The above image shows a Mylar film capacitor. The top “683” marking indicates the capacitance value, which is 68,000 picofarads (pF). To get this value, you multiply the leading digits (68 in this case) by 10 raised to the power of the last digit (3), and the result is the capacitance in picofarads (in this case, we get 68×10 3 pF).

How to read capacitance of a capacitor?

Those capacitors having capacitance of 1000pf or more, their values can be read by the 3 digits numbers (e.g. 102. 103, 105 etc.) printed on it. These 3 digits color coding can be read as follows. Generally, the overall rating is written and printed on these capacitors. For example The fig 2 (a) The value of capacitance is 47 μF (microfarad).

How do you test a film capacitor on a multimeter?

Press the “Cap” or “Continuity” button on your multimeter if it has one. This will activate the capacitance measurement mode. Read the capacitance value on the multimeter display. The value shown should be close to the rated capacitance of the film capacitor, assuming the capacitor is in good working condition.

How do you know if a film capacitor is faulty?

After a few seconds, the multimeter should display the capacitance value or indicate whether the capacitor is faulty (usually with a “low” or “open” symbol). If you’re uncertain about the results, consult a repair manual or technical expert to further diagnose the issue with the film capacitor.
