What are the primary applications for this capacitor?

It is widely used for decoupling and filtering in industrial, automotive, telecommunications, and portable electronic control units.

What should engineers review before using this part?

Engineers should review the voltage derating guidelines (derating to 50% of rated voltage is recommended for high-reliability applications) and ensure the PCB layout accommodates the 3216-18 footprint.

What are the key specifications of the T491A106K016AT?

Key specs include 10µF capacitance, 16V rated voltage, ±10% tolerance, 3.0Ω ESR, and an operating temperature range of -55°C to +125°C.

What are the sourcing risks for this component?

The T491 series is a mature, high-volume product with excellent availability. No significant supply chain risks are currently identified.

What is the pinout of T491A106K016AT?

Use the T491A106K016AT datasheet for the official pinout diagram and pin names. In PartGenie, ask Datasheet AI about T491A106K016AT pinout to locate pins, power rails, and interface signals before layout.
