Ceramic Capacitor 104 Value: Understanding its Significance and Applications

A ceramic capacitor is a type of capacitor that uses ceramic material as the dielectric. These capacitors are widely used in electronic circuits due to their reliability, low cost, and compact size. One of the most common ceramic capacitor values is 104, which is denoted by the code "104" on the capacitor's body.

What does the 104 Value Mean?

The value "104" on a ceramic capacitor represents the capacitance value in picofarads (pF). To decode the value, we need to break it down:

  • The first two digits (10) represent the significant digits of the capacitance value.
  • The third digit (4) represents the multiplier, which is 10^4 (10,000).

So, the capacitance value of a 104 ceramic capacitor is:

10 × 10^4 = 100,000 pF or 100 nF (nanofarads)

Applications of Ceramic Capacitor 104

Ceramic capacitors with a 104 value are commonly used in various electronic applications, including:

1. Coupling and Decoupling

They are used to couple or decouple AC signals in audio, radio-frequency (RF), and intermediate-frequency (IF) circuits.

2. Filtering

They are used in filter circuits to separate or combine frequency components in audio, video, and RF applications.

3. Bypassing

They are used to bypass unwanted signals and noise in power supply lines, digital circuits, and audio circuits.

4. Energy Storage

They are used to store energy in power supplies, motor control circuits, and electronic ballasts.

5. Snubbing

They are used to suppress voltage spikes and electromagnetic interference (EMI) in power supplies, motor control circuits, and electronic ballasts.

Characteristics of Ceramic Capacitor 104

Ceramic capacitors with a 104 value have the following characteristics:

Capacitance Range

The capacitance range of a 104 ceramic capacitor is typically between 90 nF to 110 nF.

Tolerance

The tolerance of a 104 ceramic capacitor is typically ±10% or ±20%.

Voltage Rating
