104 Ceramic Capacitor 100nF (0.1µF) – 5 Pack – Technical Specifications:

Handy Tips for Using the 104 Ceramic Capacitor (100nF / 0.1µF):

1: The code "104" is a standard capacitor marking, not a part number. It is read as: the first two digits (10) are the significant figures, and the third digit (4) is the multiplier — meaning 10 × 10⁴ picofarads = 100,000pF = 100nF = 0.1µF. All three values mean exactly the same thing and you will see all three used interchangeably on datasheets and in tutorials.

2: The 100nF ceramic capacitor is one of the most widely used components in electronics and is found in almost every circuit. Its primary role is as a decoupling or bypass capacitor — placed between the VCC and GND pins of ICs and microcontrollers to filter out high-frequency noise and voltage spikes on the power supply line. As a rule of thumb, place one 100nF capacitor as close as possible to the power pin of every IC in your circuit.

3: Unlike electrolytic capacitors, ceramic capacitors are non-polarised — they have no positive or negative leg and can be inserted into a circuit in either orientation without risk of damage. This makes them very beginner-friendly and quick to use on a breadboard.

4: The 50V voltage rating means the capacitor can safely handle up to 50V DC across its terminals. For typical 3.3V and 5V microcontroller projects this provides a large safety margin. Always ensure the voltage rating of any capacitor exceeds the maximum voltage it will experience in your circuit.

5: Ceramic capacitors have very low ESR (Equivalent Series Resistance) and are excellent at filtering high-frequency noise — making them the preferred choice for decoupling, signal filtering, and timing circuits. For bulk energy storage or low-frequency filtering (such as smoothing a rectified power supply), an electrolytic capacitor with a much higher capacitance value is more appropriate.
