Manufacturer: avx
# Introduction to the 0805YC274KAT2A Product Series
## 1. Overview
The 0805YC274KAT2A product series belongs to the realm of electronic components, specifically surface - mount capacitors. These components are widely used in various electronic circuits due to their reliable performance and compact size. The "0805" in the product code refers to the industry - standard package size, which is a common and well - recognized form factor in the electronics manufacturing world.
## 2. Package Size (0805)
The 0805 package has specific dimensions that make it suitable for a wide range of applications. The length of the component is approximately 2.03 mm, and the width is around 1.27 mm. This relatively small size allows for high - density circuit board designs, enabling manufacturers to fit more components on a single printed circuit board (PCB). It is also compatible with automated pick - and - place machines, which are commonly used in mass - production electronics manufacturing processes. This compatibility ensures efficient and accurate assembly, reducing production time and costs.
## 3. Capacitance Value (274)
The "274" in the product code represents the capacitance value of the capacitor. In the capacitor coding system, the first two digits (27 in this case) are significant figures, and the third digit (4) is the multiplier. Using the formula \(C = ab\times10^c\) (where \(a\) and \(b\) are the first two digits and \(c\) is the third digit), we can calculate the capacitance. For 274, the capacitance \(C=27\times10^4\) picofarads (\(pF\)). Converting this to microfarads (\(\mu F\)), since \(1\mu F = 10^6pF\), we get \(C = 0.27\mu F\). This capacitance value is suitable for a variety of filtering, coupling, and bypassing applications in electronic circuits.
## 4. Tolerance (K)
The letter "K" indicates the tolerance of the capacitor. In the capacitor tolerance coding system, "K" represents a tolerance of ±10%. This means that the actual capacitance value of the 0805YC274KAT2A capacitor can vary within 10% of the nominal value of \(0.27\mu F\). So, the actual capacitance can range from \(0.27\times(1 - 0.1)=0.243\mu F\) to \(0.27\times(1 + 0.1)=0.297\mu F\). This tolerance level is acceptable for many general - purpose electronic applications where a small variation in capacitance does not significantly affect the overall performance of the circuit.
## 5. Dielectric Material (Y)
The "Y" in the product code typically refers to a specific type of dielectric material used in the capacitor. Different dielectric materials have different electrical properties, such as dielectric constant, temperature coefficient, and insulation resistance. The dielectric material used in the 0805YC274KAT2A series is chosen to provide a good balance between capacitance stability, temperature performance, and cost. It may offer relatively high dielectric constant, which allows for a higher capacitance value to be achieved in a small package size.
## 6. Temperature Coefficient and Stability
The capacitor in the 0805YC274KAT2A series is designed to have a certain temperature coefficient, which describes how the capacitance changes with temperature. This is important because electronic devices often operate in a wide range of temperatures. The specific temperature coefficient of this series
