474 Capacitor FAQs
What does 474 mean on a capacitor?
The marking “474” on a capacitor indicates its capacitance value in picofarads (pF). The first two digits, “47,” are the significant figures, and the third digit, “4,” is the multiplier, meaning 10,000. So, 47×10,000=470,00047 \times 10,000 = 470,000 pF, or 0.47 µF.
What is the value of a 0.47 µF capacitor?
A 0.47 µF capacitor has a capacitance of 0.47 microfarads, which is equal to 470,000 picofarads (pF) or 470 nanofarads (nF). This value is commonly used in circuits for decoupling or filtering.
What is a 474K capacitor?
A “474K” capacitor has a capacitance of 0.47 µF (470,000 pF) with a tolerance of ±10%. The “K” represents the tolerance grade. These capacitors are often used in power supply filters, coupling, and decoupling applications.
What is the use of a 474J 400V capacitor?
A “474J 400V” capacitor is a 0.47 µF capacitor with a tolerance of ±5% (“J”) and a maximum voltage rating of 400 volts. It’s commonly used in high-voltage circuits, such as power supplies, motor run circuits, and AC line filtering.
What does K stand for on a capacitor?
The “K” on a capacitor indicates the tolerance of its capacitance value. Specifically, “K” represents a tolerance of ±10%. This shows how much the actual capacitance can vary from the labeled value.
What does J or K mean in a capacitor?
J and K in capacitors refer to the tolerance rating. J indicates a tolerance of ±5%, and K represents a tolerance of ±10%. These letters help you understand how much the actual capacitance may vary from the specified value, which is critical for precision in some circuits.
Is a higher Farad capacitor better?
It depends on the application. A higher Farad capacitor stores more charge, which can improve energy supply in circuits like amplifiers or power systems. However, using a higher Farad capacitor than needed might negatively impact circuit performance, especially in timing-sensitive devices. Always match the capacitance to the design specifications.
