series introduction
# Introduction to the C3216X5R1H106K Product Series
## 1. Overview
The C3216X5R1H106K product series belongs to the category of multilayer ceramic capacitors (MLCCs). These capacitors are essential passive components widely used in various electronic circuits due to their excellent electrical properties, compact size, and high reliability. The specific model code “C3216X5R1H106K” contains important information about the capacitor's characteristics, which will be detailed in the following sections.
## 2. Physical Characteristics
### 2.1 Dimensions
The “C3216” in the model code indicates the capacitor's size in the imperial measurement system. It corresponds to a length of 0.126 inches (3.2 mm) and a width of 0.063 inches (1.6 mm). This relatively small size makes it suitable for applications where space is limited, such as in mobile devices, wearable electronics, and compact printed circuit boards (PCBs).
### 2.2 Construction
MLCCs in the C3216X5R1H106K series are constructed by stacking multiple layers of ceramic dielectric material and internal electrodes. The ceramic dielectric is sandwiched between the electrodes, and the entire structure is then encapsulated in a protective outer layer. This construction allows for a high capacitance value to be achieved in a small physical package.
## 3. Electrical Characteristics
### 3.1 Capacitance
The “106” in the model code represents the capacitance value of the capacitor. Using the standard capacitor coding system, the first two digits (10) are the significant figures, and the third digit (6) is the multiplier. So, the capacitance value is \(10\times10^{6}\) picofarads (pF), which is equivalent to 10 microfarads (\(\mu F\)). This relatively high capacitance makes the capacitor suitable for applications that require energy storage, filtering, and decoupling.
### 3.2 Dielectric Type
The “X5R” indicates the dielectric type of the capacitor. X5R is a Class II dielectric, which offers a good balance between capacitance, temperature stability, and cost. It has a temperature coefficient of capacitance (TCC) of ±15% over a temperature range of -55°C to +85°C. This means that the capacitance value of the capacitor will remain within ±15% of its nominal value within this temperature range, making it suitable for a wide variety of operating environments.
### 3.3 Voltage Rating
The “1H” in the model code represents the voltage rating of the capacitor. In the standard coding system, “1H” corresponds to a voltage rating of 50 volts (V). This means that the capacitor can safely operate at a maximum DC voltage of 50 V without experiencing breakdown or other electrical failures.
### 3.4 Tolerance
The “K” at the end of the model code indicates the capacitance tolerance of the capacitor. “K” represents a tolerance of ±10%. This means that the actual capacitance value of the capacitor may vary by up to ±10% from its nominal value of 10 \(\mu F\).
## 4. Applications
### 4.1 Power Supply Filtering
Due to its relatively high capacitance and good temperature stability, the C3216X5R1H106K capacitor is commonly used in power supply circuits for filtering purposes. It can smooth out the DC voltage by storing and releasing electrical energy, reducing ripple voltage and noise in the power supply. This helps to ensure a stable and clean power supply for other components in the circuit.
