series introduction
# Introduction to the CGA1A2X7R1C221K030BA Product Series
## Overview
The CGA1A2X7R1C221K030BA product series represents a cutting - edge line of electronic components, specifically ceramic capacitors. These capacitors are engineered to meet the diverse and demanding requirements of modern electronic circuits, offering high - performance characteristics and reliable operation in a wide range of applications.
## Key Specifications
### Capacitance
The series features a capacitance value of 220 pF (since 221 in the capacitor code means \(22\times10^{1}\) pF). This capacitance value is carefully calibrated to provide the necessary charge storage and release capabilities for various circuit functions, such as filtering, coupling, and bypassing.
### Dielectric Material
The use of X7R dielectric material is a significant advantage of this product series. X7R is a Class II dielectric, known for its relatively high dielectric constant. This allows the capacitors to achieve a relatively large capacitance in a small physical size. Additionally, X7R dielectric has good temperature stability, with a capacitance change of ±15% over a temperature range of - 55°C to +125°C. This makes the CGA1A2X7R1C221K030BA capacitors suitable for applications where the operating temperature may vary significantly.
### Voltage Rating
The capacitors in this series have a voltage rating of 16 V. This voltage rating indicates the maximum voltage that the capacitor can safely withstand without experiencing breakdown or significant degradation in performance. It is crucial for ensuring the long - term reliability of the capacitor in circuits where the applied voltage may fluctuate.
### Tolerance
The tolerance of the capacitance is specified as ±10% (indicated by the 'K' in the part number). This relatively tight tolerance means that the actual capacitance value of the capacitor will be within 10% of the nominal 220 pF value. It is important in applications where precise capacitance values are required for accurate circuit operation, such as in resonant circuits or frequency - sensitive filters.
### Package Size
The specific package size of the CGA1A2X7R1C221K030BA is defined by the '030BA' part of the part number. This compact package size allows for high - density PCB (Printed Circuit Board) layouts, which is essential in modern electronic devices where space is often at a premium. The small form factor also contributes to reduced parasitic effects, such as stray capacitance and inductance, which can improve the overall performance of the circuit.
## Performance Characteristics
### Low Equivalent Series Resistance (ESR)
The CGA1A2X7R1C221K030BA capacitors exhibit low ESR values. Low ESR is beneficial in applications where high - frequency performance is required, such as in switching power supplies. It helps to reduce power losses and heat generation, improving the efficiency of the circuit and extending the lifespan of the components.
### High Self - Resonant Frequency (SRF)
Due to their design and construction, these capacitors have a relatively high self - resonant frequency. The high SRF allows the capacitors to effectively filter high - frequency noise and interference in circuits, making them suitable for use in RF (Radio Frequency) and high - speed digital applications.
## Applications
### Power Supply Circuits
In power supply circuits, the CGA1A2X7R1C221K030BA capacitors can be used for filtering purposes. They can smooth out the DC voltage output by removing ripple and noise, ensuring a stable power supply for other components in the circuit. Their low ESR and high SRF make them particularly effective in switching power supplies, where they
