series introduction
# Introduction to the C1005X5R1E224M Product Series
## 1. Overview
The C1005X5R1E224M product series belongs to the category of multilayer ceramic capacitors (MLCCs). These capacitors are essential passive components widely used in various electronic circuits. Their small size, high capacitance, and stable performance make them a popular choice in modern electronic devices.
## 2. Product Naming Convention
Let's break down the product code “C1005X5R1E224M” to understand its key characteristics:
- **C**: Usually indicates that it is a capacitor.
- **1005**: This represents the physical size of the capacitor, also known as the chip size. In the metric system, 1005 corresponds to a length of 1.0 mm and a width of 0.5 mm. This small size makes it suitable for applications where space is limited, such as in mobile phones, wearables, and other compact electronic devices.
- **X5R**: It is the dielectric type of the capacitor. The X5R dielectric has a relatively stable capacitance over a wide temperature range. The “X” indicates that the lower temperature limit is -55°C, and “5” means the upper temperature limit is 85°C. The capacitance change within this temperature range is typically within ±15%, which ensures reliable performance in different environmental conditions.
- **1E**: This part of the code is related to the rated voltage. In the EIA standard, “1E” represents a rated voltage of 25V. This means the capacitor can safely operate at a maximum DC voltage of 25 volts without significant degradation in performance or risk of breakdown.
- **224**: The capacitance value is encoded in this number. Using the standard capacitor value coding system, the first two digits (22) are the significant figures, and the third digit (4) is the multiplier. So, the capacitance value is 22 × 10⁴ pF, which is equal to 0.22 μF (microfarads).
- **M**: It indicates the tolerance of the capacitance. “M” stands for a tolerance of ±20%. This means that the actual capacitance of the capacitor can vary within ±20% of the nominal value (0.22 μF).
## 3. Electrical Characteristics
### Capacitance
With a nominal capacitance of 0.22 μF, the C1005X5R1E224M capacitor can store and release electrical charge as required by the circuit. This capacitance value is suitable for a variety of applications, such as decoupling, filtering, and coupling in electronic circuits.
### Voltage Rating
The rated voltage of 25V allows the capacitor to be used in circuits where the operating voltage does not exceed this limit. It is important to ensure that the voltage across the capacitor in the actual application does not exceed the rated voltage to avoid damage to the capacitor and potential circuit malfunctions.
### Temperature Coefficient
Thanks to the X5R dielectric, the capacitor has a relatively stable capacitance over the temperature range of -55°C to 85°C. This temperature stability is crucial in applications where the operating temperature may vary, such as in automotive electronics, industrial control systems, and outdoor electronic devices.
### Equivalent Series Resistance (ESR)
The ESR of the C1005X5R1E224M capacitor is relatively low. A low ESR is beneficial in applications where high - frequency performance is required, such as in power supply circuits. It helps to reduce power losses and improve the efficiency of the circuit.
