series introduction
# Introduction to the TAJA474M Product Series
## Overview
The TAJA474M product series represents a significant advancement in the field of electronic components, specifically in the realm of tantalum capacitors. These capacitors are engineered to meet the diverse and demanding requirements of modern electronic circuits, offering a reliable and high - performance solution for a wide range of applications.
## Key Features
### Capacitance and Tolerance
The TAJA474M series is characterized by its specific capacitance value. The "474" in the part number indicates a capacitance of 470,000 picofarads (pF), which is equivalent to 0.47 microfarads (μF). This capacitance value is carefully calibrated to provide the necessary charge storage capacity for various circuit designs. The "M" in the part number typically represents a capacitance tolerance of ±20%. This tolerance range ensures that the actual capacitance of the capacitor will fall within an acceptable range around the nominal value, allowing for consistent performance in different operating conditions.
### Voltage Rating
These tantalum capacitors come with a well - defined voltage rating. The voltage rating is a crucial parameter as it determines the maximum voltage that the capacitor can safely withstand without experiencing breakdown or other forms of failure. The TAJA474M series is designed to handle specific voltage levels, which makes it suitable for use in circuits where the voltage requirements are within its rated capacity. This ensures the long - term reliability and safety of the electronic systems in which they are installed.
### Low ESR (Equivalent Series Resistance)
One of the standout features of the TAJA474M series is its low equivalent series resistance (ESR). ESR is an important characteristic of capacitors as it affects the efficiency and performance of the circuit. A low ESR value means that the capacitor can charge and discharge more quickly, resulting in reduced power losses and improved overall circuit efficiency. In applications such as power supplies and voltage regulation circuits, a low - ESR capacitor like those in the TAJA474M series can help to minimize voltage ripple and improve the stability of the output voltage.
### High Ripple Current Handling
The TAJA474M series is capable of handling high ripple currents. Ripple current is the alternating current component that flows through a capacitor in a circuit. Capacitors need to be able to handle this ripple current without overheating or experiencing excessive degradation. The high ripple current handling capability of the TAJA474M series makes it suitable for use in high - power applications, such as switching power supplies and motor control circuits, where large amounts of ripple current are present.
### Temperature Stability
These capacitors exhibit excellent temperature stability. They are designed to maintain their electrical characteristics over a wide range of operating temperatures. This is important because electronic components often need to operate in environments with varying temperatures. The TAJA474M series can withstand temperature fluctuations without significant changes in capacitance, ESR, or other key parameters, ensuring reliable performance in different thermal conditions.
## Physical Characteristics
### Package Size
The TAJA474M series is available in a specific package size. The package size is designed to be compact and suitable for surface - mount technology (SMT) applications. This makes it easy to integrate the capacitors into printed circuit boards (PCBs) during the manufacturing process. The small form factor also allows for more efficient use of board space, which is particularly important in modern, miniaturized electronic devices.
### Lead Configuration
The lead configuration of the TAJA474M series is optimized for easy soldering and reliable electrical connection. The leads are designed to provide a secure and low - resistance connection to the PCB, ensuring good electrical conductivity and mechanical stability. This helps to prevent issues such as loose connections or intermittent electrical contact, which can lead to circuit failures.
