Unlock New Capabilities

• Past Projects If you've already experimented with basic power filtering using standard 0.1 µF (104) or 10 µF electrolytic capacitors, you understand the basics of stabilizing voltage. However, standard components are often too large in capacitance and physical size to effectively filter out ultra-high-frequency noise in sensitive circuits.
• Feature Upgrade This 0.002 pF capacitor unlocks the ability to build and tune precision RF (Radio Frequency) circuits, ultra-high-frequency oscillators, and specialized timing circuits. It allows you to filter out parasitic interference at the gigahertz level without dampening the primary signal of your communication modules.
• Effort Level: Advanced

Minimum hardware to get started:

• RF Signal Generator or Oscilloscope: to accurately measure and verify the filtering effect at ultra-high frequencies.
• High-Frequency PCB: standard breadboards introduce too much parasitic capacitance to reliably test a 0.002 pF component; a properly routed PCB is required.
• Precision Soldering Iron: to securely mount the through-hole leads with minimal excess wire length, preventing unwanted inductance.

Included in the Box:

• 1× 0.002 pF Ceramic Disc Capacitor

Frequently Asked Questions

• Is the 0.002 pF ceramic capacitor compatible with standard Arduino boards?
  Yes, but standard Arduino (16MHz) frequencies generally do not require sub-picofarad filtering; it is intended for much higher frequency RF circuits.
• Can I use this capacitor on a standard breadboard?
  No, a standard breadboard introduces 2-5 pF of parasitic capacitance, which will completely override the 0.002 pF value of this component.
• Does this capacitor work in AC circuits?
  It can be used in high-frequency AC signal circuits, provided the voltage does not exceed the 50V rating.
• Can I use multiple 0.002 pF capacitors in parallel to increase capacitance?
  Yes, wiring them in parallel will add their capacitance values together, though precise PCB routing is required to maintain accuracy.
• What is the maximum voltage this capacitor can handle?
  It is rated for a maximum of 50V DC.
• Can I use this capacitor on a 12V power supply line?
  Yes, 12V is safely below the 50V maximum rating.
• Does this capacitor draw a continuous current?
  No, capacitors do not draw continuous DC current; they only draw current while charging or when passing AC signals.
• Does it matter which way I solder the capacitor into my PCB?
  No, ceramic capacitors are non-polarized, so orientation does not matter.
• How long can I leave the leads when soldering?
  You must keep the leads as short as physically possible to minimize parasitic inductance, which is critical at high frequencies.
• Where should I place this capacitor for RF bypassing?
  Place it as physically close to the signal line and ground plane connection of the target IC as possible.
