For the size of CBB capacitor capacity, we most commonly used units are PF, NF, UF, but on the CBB capacitor, the printed capacitance is generally three digits, how much capacity do they represent? What is the capacity of cbb capacitor 155j?
In fact, the capacity size represented by three digits is not mysterious, taking CBB capacitance 155J as an example, 155 refers to the size of CBB capacitance, where the last 5 represents the number of 0, the unit of capacity is PF.
The specific conversion formula is: 155=15 00000PF.
In other words, if it is a three-digit number representing the capacity of the capacitor, the last number is a number representing 0, and the unit is PF. For example, 224= 220,00PF.
Our most commonly used capacity unit is UF, how to convert it? Again, take the 155 capacitor as an example:
155=1500000PF=1500NF=1.5uf, so the void size of the CBB capacitor 155J is 1.5uf.
J represents the capacity error of the capacitor, which means that the capacity error is ±5%. It should be known that CBB capacitors are limited by current production technology, and the capacity is difficult to be 100% accurate, and there are certain errors.
For the cbb155j capacitor, its specific capacity needs to be confirmed according to the manufacturer's specifications. In general, the cbb155j capacitor is a polypropylene film capacitor whose capacity may range from a few nanofads to a few hundred microfads. Different application scenarios require different capacitance capacities, so the selection of capacitors needs to be determined according to specific needs. In addition, the cbb155j capacitor also has good high-frequency characteristics, high stability, small temperature drift and other characteristics, so it is widely used in the design of electronic components.
