100nF Capacitor 0.1uF 104J High Frequency Multilayer Ceramic
A multilayer ceramic capacitor (MLCC),0.1uF/104/100nF Capacitor,is an electronic component that is commonly used for its capacitance properties in a wide range of electronic circuits and devices. It is constructed using multiple layers of ceramic material, typically made of ceramic dielectric materials such as barium titanate or titanium dioxide.
First let us understand the meaning of this 104 code.
Please note that the EIA-96 code system is commonly used in the United States, while the EIA-600 code system is often used in metric regions. These codes represent the significant figures and the number of zeros to be added after them to denote the capacitance value.
Keep in mind that this table includes some common values, but there are many other capacitance values available beyond those listed. The codes provided here should help you identify and select the appropriate capacitor values based on the code printed on the component or specified in a datasheet.
Multilayer Ceramic 100nF Capacitor Structure
Multilayer ceramic 100nF capacitor are widely used electronic components that consist of alternating layers of ceramic dielectric material and metal electrodes. The specific structure of MLCCs can be described as follows:
- Ceramic Dielectric Material: The ceramic dielectric material is the main component of the MLCC. It is typically made of ceramic materials such as barium titanate (BaTiO3), which exhibits excellent dielectric properties. The dielectric material is formulated and processed to achieve the desired capacitance and other electrical characteristics.
- Metal Electrodes: MLCCs have metal electrodes that are alternately stacked with the ceramic layers. The most commonly used electrode materials are silver (Ag) and palladium silver (Pd/Ag). The electrodes are usually applied to the ceramic layers through a screen printing process.
- Inner Electrode Configuration: MLCCs have different inner electrode configurations, which determine their capacitance values and other characteristics. The two most common configurations are:
a. Parallel Plate Configuration: In this configuration, the metal electrodes on each layer are aligned in parallel. The inner electrode configuration can be visualized as multiple parallel plate capacitors stacked together.
b. Interdigitated Configuration: In this configuration, the metal electrodes on each layer are interdigitated, creating a more compact structure. The interdigitated configuration increases the effective capacitance per unit volume compared to the parallel plate configuration.
- Terminations: MLCCs have terminations on both ends that provide electrical connections to the electrodes. The terminations are typically made of a conductive material such as silver (Ag) or nickel (Ni). These terminations are important for soldering or surface mount assembly onto printed circuit boards (PCBs).
Advantages of Multilayer Ceramic 100nF Capacitor
Multilayer ceramic 100nf capacitor (MLCCs) offer several advantages that make them a popular choice in electronic circuits. Here are some of the key advantages of MLCCs:
