47pF Ceramic Capacitor (Pack of 5)

Wiring Connections:

• Through-Hole Type: For through-hole capacitors, the leads are inserted into holes on a PCB and soldered.
• Surface-Mount Type: For SMD capacitors, the capacitor is placed on the surface of the PCB and soldered at the contact pads.

Power:

• Power Dissipation: Generally minimal; capacitors do not consume power but may dissipate some heat in high-frequency applications.
• Voltage Rating: Ensure the capacitor’s voltage rating exceeds the maximum voltage applied in the circuit.

Input and Output:

• Input: Connect the capacitor across the circuit elements where filtering or decoupling is needed.
• Output: The capacitor helps in smoothing signals, filtering noise, or stabilizing voltage.

Physical Characteristics:

• Size: The physical size can vary; for SMD types, it’s usually specified in terms of package dimensions (e.g., 0603, 0805). Through-hole types are  small disc or cylindrical shapes.
• Shape:  disc-shaped for through-hole or rectangular for SMD.

Technical Specifications:

• Temperature Coefficient: Usually specified as a class (e.g., C0G, X7R) which indicates how capacitance changes with temperature.
• Dielectric Material: Made from ceramic materials, such as Class 1 (C0G, NP0) or Class 2 (X7R, Y5V) dielectrics, affecting temperature stability and capacitance variation.

Additional Features:

• Low Leakage Current: Ceramic capacitors generally have very low leakage currents compared to electrolytic capacitors.
• High Frequency Performance: Suitable for high-frequency applications due to their low ESR.

How to Use:

1. Determine Placement: Identify where the capacitor is needed in the circuit for filtering, decoupling, or other purposes.
2. For Through-Hole Capacitors:
   • Insert the leads into the PCB holes.
   • Solder the leads to the PCB.
   • Trim any excess lead length if necessary.
3. For Surface-Mount Capacitors:
   • Place the capacitor on the PCB at the designated pads.
   • Solder the capacitor leads to the PCB.
4. Check Orientation: For ceramic capacitors, there’s no polarity; they can be installed in either direction.
5. Verify Functionality: After installation, ensure the capacitor is performing as expected within the circuit.

The 47pF ceramic capacitor is a small but important component used in various electronic circuits for filtering, decoupling, and signal processing. Available in packs of 5, these capacitors offer high stability and durability with minimal leakage and resistance. Their wide range of applications and robust characteristics make them a versatile choice for both high-frequency and general electronic projects.
