Decoding the 155J 400V CAPACITOR Datasheet
At its core, a 155J 400V CAPACITOR Datasheet provides a comprehensive overview of the capacitor’s electrical and physical characteristics. It acts as a blueprint, detailing everything from its capacitance value and voltage rating to its operating temperature range and physical dimensions. Understanding the datasheet allows engineers and hobbyists to make informed decisions about whether this particular capacitor is suitable for their specific application. It provides critical insights for ensuring circuit stability and preventing component failure.
The “155J 400V” designation itself reveals key information about the capacitor. “155” indicates the capacitance value, which is derived as follows: the first two digits (15) are the significant figures, and the third digit (5) is the multiplier, representing the number of zeros. Therefore, 155 translates to 15 x 105 picofarads (pF), or 1.5 μF (microfarads). “J” denotes the tolerance, typically ±5%. And “400V” specifies the maximum DC voltage that the capacitor can safely withstand. Datasheets elaborate on these core specifications and provide additional context through sections like:
- Electrical Characteristics: Including capacitance tolerance, dissipation factor, insulation resistance.
- Environmental Characteristics: Such as operating temperature range, storage temperature range, and humidity resistance.
- Physical Dimensions: Detailing the capacitor’s size, lead spacing, and material composition.
These capacitors are used in a very wide variety of applications, from power supplies and filtering circuits to signal coupling and decoupling. Consider this very simple example of using it in a power supply circuit:
- The power supply circuit rectifies AC voltage to DC.
- The capacitor stores electrical energy.
- The capacitor provides a smoother DC output by reducing ripple.
The datasheet will give you all the specifics to make an informed decision about whether this capacitor is the right choice for the job.
