What are the key specifications?

100µF capacitance, 10V DC rating, ±10% tolerance, 1.2Ω ESR, and a 3528-21 (B-case) footprint.

What should engineers review before using this part?

Review the voltage derating guidelines; KEMET recommends using only 50% of the rated voltage for applications up to 85°C to ensure long-term reliability.

Is this capacitor polar?

Yes, it is a polar device. The positive terminal is marked with a stripe and sometimes a beveled edge on the case.

What is the sourcing status?

The part is currently active and widely available with high stock levels, making it a low-risk choice for new designs.

What is the pinout of T491B107K010AT?

Use the T491B107K010AT datasheet for the official pinout diagram and pin names. In PartGenie, ask Datasheet AI about T491B107K010AT pinout to locate pins, power rails, and interface signals before layout.
