Manufacturer: kemet
# Introduction to the T491B156K016AT Product Series
## Overview
The T491B156K016AT belongs to a specialized product series that is likely a tantalum capacitor. Tantalum capacitors are widely recognized in the electronics industry for their high capacitance per volume, stable performance, and reliability. This particular model, with its unique alphanumeric designation, offers specific electrical characteristics and features that make it suitable for a variety of applications.
## Electrical Specifications
### Capacitance
The "156" in the model number indicates the capacitance value. In the capacitor naming convention, this translates to a capacitance of 15 × 10⁶ picofarads (pF), which is equivalent to 15 microfarads (μF). This relatively high capacitance value allows the capacitor to store a significant amount of electrical charge, making it useful for applications that require energy storage and filtering.
### Tolerance
The "K" in the model number represents the capacitance tolerance. A "K" tolerance indicates a ±10% variation from the nominal capacitance value. This means that the actual capacitance of the T491B156K016AT capacitor can range from 13.5 μF (15 μF - 10%) to 16.5 μF (15 μF + 10%). The relatively tight tolerance ensures that the capacitor's performance remains consistent within a specific range, which is crucial for applications where precise capacitance values are required.
### Voltage Rating
The "016" in the model number indicates the rated voltage of the capacitor. In this case, the capacitor is rated for 16 volts (V). This means that the capacitor can safely operate at voltages up to 16 V without the risk of breakdown or damage. It is important to note that the voltage rating should always be considered when selecting a capacitor for a particular application to ensure that it can withstand the maximum voltage that will be applied across it.
### Temperature Coefficient
Tantalum capacitors typically have a relatively stable temperature coefficient, which means that their capacitance value changes only slightly with temperature variations. The T491B156K016AT is likely to have a temperature coefficient that is suitable for a wide range of operating temperatures, making it suitable for use in both indoor and outdoor environments.
## Physical Characteristics
### Package Type
The T491B156K016AT is likely to be available in a surface-mount package, which is commonly used in modern electronic circuits. Surface-mount packages offer several advantages, including smaller size, lower profile, and better compatibility with automated assembly processes. This makes them ideal for use in compact electronic devices such as smartphones, tablets, and wearables.
### Dimensions
The exact dimensions of the T491B156K016AT will depend on the specific package type. However, surface-mount tantalum capacitors are generally small in size, with typical dimensions ranging from a few millimeters to a few centimeters. The small size of these capacitors allows them to be easily integrated into densely packed circuit boards, saving valuable space and reducing the overall size of the electronic device.
### Termination
The capacitor is likely to have metal terminations that provide a reliable electrical connection to the circuit board. The terminations are designed to be compatible with standard soldering processes, ensuring a secure and stable connection.
## Applications
### Power Supply Filtering
One of the most common applications of the T491B156K016AT is in power supply filtering. In a power supply circuit, the capacitor is used to smooth out the DC voltage by filtering out any ripple or noise that may be present. The high capacitance value of the T491B15
