0.1uF - (104) Ceramic Capacitor - 5 Pieces pack

Technical Details

• Dielectric Material: Titanium Dioxide or Barium Titanate.

• Lead Material: Tinned copper-clad steel.

• Marking: "104" (10 followed by 4 zeros = 100,000 pF = 0.1uF).

Prototyping and Engineering Tips from Robogears

• The Decoupling Rule: CRITICAL: For digital circuits (Arduino, ESP32, etc.), place one 0.1uF capacitor as close as possible to the VCC and GND pins of every IC on your board. This acts as a local energy reservoir, preventing the "voltage sag" that occurs when an IC switches states rapidly.

• Code Translation: The number "104" is the standard EIA code. The first two digits (10) are the value, and the third digit (4) is the multiplier (104). This equals 100,000 picofarads (pF), which is 100 nanofarads (nF) or 0.1 microfarads (uF).

• High-Frequency Filtering: While electrolytic capacitors are good for low-frequency smoothing, they have high internal inductance. Ceramic capacitors have very low inductance, making them much better at filtering out the high-frequency "ringing" generated by switching power supplies or motors.

• Debouncing Switches: Use a 104 capacitor in parallel with a mechanical push-button to help "debounce" the signal. The capacitor absorbs the tiny electrical arcs and mechanical bounces, providing a cleaner pulse to your microcontroller.

• Voltage Margin: Even though these are rated for 50V, they are commonly used in 3.3V, 5V, and 12V circuits. This high voltage overhead makes them extremely robust against voltage surges in low-voltage logic circuits.

Package Includes

• 5 x 0.1uF (104) Ceramic Disc Capacitors

Disclaimer: Product images are shown for illustrative purposes only. The exact shade of the orange/tan coating or the font style of the "104" marking may vary between manufacturing batches, but all technical specifications and 0.1uF performance standards remain as described.

Safety Warning: Ensure the capacitor is used within its rated 50V DC limit. Ceramic capacitors can crack if subjected to extreme mechanical stress or bending of the leads at the very base of the disc. Always handle with care during installation.
