series introduction
# Introduction to the T491X107K016AS Product Series
## Overview
The T491X107K016AS product series represents a cutting - edge line of electronic components, specifically tantalum capacitors. These capacitors are engineered to meet the diverse and demanding requirements of modern electronic circuits, offering a combination of high performance, reliability, and compact design.
## Key Specifications
### Capacitance
The "107" in the part number indicates a capacitance value. In the capacitor naming convention, this translates to a capacitance of 10 × 10⁷ picofarads, which is equivalent to 100 microfarads (μF). This relatively high capacitance value makes the T491X107K016AS capacitors suitable for applications where large amounts of charge need to be stored and released, such as power supply filtering and energy storage in electronic devices.
### Tolerance
The "K" in the part number represents the capacitance tolerance. A "K" tolerance means that the actual capacitance of the capacitor can vary by ±10% from the nominal value. For example, for a 100 μF capacitor with a K tolerance, the actual capacitance can range from 90 μF to 110 μF. This tolerance level provides a good balance between precision and cost - effectiveness, making it suitable for a wide range of general - purpose applications.
### Voltage Rating
The "016" in the part number indicates the voltage rating of the capacitor. In this case, the voltage rating is 16 volts (V). This means that the capacitor is designed to operate safely at voltages up to 16 V. It is crucial to ensure that the voltage across the capacitor in the application does not exceed this rating to prevent damage to the capacitor and potential failure of the circuit.
### Case Size and Package
The T491 series typically comes in a specific case size and package that is optimized for surface - mount technology (SMT). The compact size of the SMT package allows for easy integration onto printed circuit boards (PCBs), making it suitable for modern, miniaturized electronic devices. The small footprint also helps in reducing the overall size of the PCB, which is beneficial for applications where space is limited, such as mobile phones, tablets, and wearable devices.
## Performance Characteristics
### Low Equivalent Series Resistance (ESR)
The T491X107K016AS capacitors are designed to have a low equivalent series resistance. ESR is an important parameter as it affects the efficiency of the capacitor in filtering and energy storage applications. A low ESR means that the capacitor can charge and discharge more quickly, reducing power losses and heat generation. This results in improved overall circuit performance and reliability, especially in high - frequency applications.
### High Ripple Current Handling
These capacitors can handle relatively high ripple currents. Ripple current is the alternating current component that flows through the capacitor in a power supply circuit. The ability to handle high ripple currents makes the T491X107K016AS capacitors suitable for use in power supplies, where they can effectively filter out the ripple voltage and provide a stable DC output.
### Good Temperature Stability
The T491X107K016AS series exhibits good temperature stability. The capacitance and other electrical properties of the capacitor change minimally over a wide temperature range. This ensures consistent performance in different environmental conditions, making the capacitors suitable for use in a variety of applications, including automotive electronics, industrial control systems, and aerospace applications.
## Applications
### Power Supply Filtering
One of the primary applications of the T491X107K016AS capacitors is in power supply filtering. In a power supply circuit, the capacitor is used to
