What are the key specifications?

Key specs include a 22µF capacitance, 16V rated voltage, 6Ω maximum ESR, and a -55°C to +125°C operating temperature range.

What should engineers review before using this capacitor?

Engineers should review the derating requirements for low-impedance circuits and ensure the ripple voltage does not exceed the rated limits.

What are the environmental considerations?

The device is moisture sensitive (MSL 2) and should be protected from direct contact with water, oil, salt, and active gases.

What is the sourcing risk?

The part is currently active and widely available, with moderate supply risk typical for standard tantalum capacitors.

What is the pinout of CA45-A-16V-22uF-K?

Use the CA45-A-16V-22uF-K datasheet for the official pinout diagram and pin names. In PartGenie, ask Datasheet AI about CA45-A-16V-22uF-K pinout to locate pins, power rails, and interface signals before layout.
