Non-returnable
Rs.10.00
A picofarad (pF) capacitor is a unit of capacitance used to measure the electrical charge storage capacity of a capacitor. It is a very small unit of capacitance, equivalent to one trillionth (10^(-12)) of a farad (F), which is the standard unit of capacitance. Picofarads are often used to express the capacitance of small capacitors in electronic circuits.

Here are some key points about picofarad capacitors:
1. Capacitance Value: A picofarad (pF) capacitor has a capacitance value of 10^(-12) farads. In mathematical notation, 1 pF = 1 x 10^(-12) F.
2. Small Capacitance: Picofarad capacitors have very small capacitance values compared to capacitors in other common units like microfarads (µF) or nanofarads (nF). For example, a capacitor with a capacitance of 1 µF is equivalent to 1,000,000 picofarads (1 µF = 1,000,000 pF).
3. Applications: Picofarad capacitors are used in various electronic circuits and applications where small capacitance values are required. They are often used in high-frequency circuits, such as radio-frequency (RF) circuits, oscillators, and filters, where their small capacitance can have a significant impact.
4. Symbol: In circuit diagrams and schematics, capacitors are typically represented by the symbol "C," and the value of the capacitance (in picofarads, nanofarads, or microfarads) is usually specified nearby.
5. Tolerance: Like capacitors in other units, picofarad capacitors can come with tolerance values that indicate the allowable variation in capacitance from the specified value. Common tolerance values include ±5% and ±10%.
6. Dielectric Material: The dielectric material used in picofarad capacitors can vary depending on the specific application and requirements. Common dielectric materials include ceramic, polyester, polypropylene, and others.
7. Voltage Rating: Picofarad capacitors have voltage ratings that indicate the maximum voltage they can safely handle. It's essential to choose a capacitor with an appropriate voltage rating to prevent damage or failure in a circuit.
8. Package Size: Picofarad capacitors come in various package sizes and types, including through-hole and surface-mount components. The choice of package size depends on the specific application and available space on the circuit board.
9. Common Values: Common capacitance values in picofarads include 10 pF, 22 pF, 100 pF, 220 pF, and 1000 pF (1 nF).
10. Decade Prefixes: In electronic engineering, capacitance values can be expressed using prefixes to denote different orders of magnitude. For example, 1 pF is a picofarad, 1 nF is a nanofarad, and 1 µF is a microfarad.
