概述

Description

The T491B476K010AT is a surface-mount tantalum capacitor manufactured by KEMET. It features a capacitance of 47 microfarads (µF) with a voltage rating of 10 volts (V). This capacitor is designed for applications requiring stable capacitance, low equivalent series resistance (ESR), and reliable performance under varying temperatures and voltages. The "B" in the part number indicates a tolerable capacitance variation of ±10%, while the "K" denotes a temperature coefficient, typically -55°C to +125°C. Tantalum capacitors like the T491 series are widely used in power management, filtering, and decoupling applications due to their compact size and high capacitance-to-volume ratio. They are particularly suited for portable electronics, automotive, and industrial devices. It's essential to follow proper handling guidelines, as tantalum capacitors can be sensitive to overvoltage conditions.
