What are the key applications for this capacitor?

It is widely used in mobile communications, cameras, computers, and automotive electronic systems for DC or pulsating circuits.

What design precautions should be taken?

In low-impedance circuits, it is recommended to derate the voltage to 1/3 of the rated value. Always observe correct polarity, as reverse voltage will cause permanent failure.

What are the key electrical specifications?

It features a ±10% capacitance tolerance, a maximum ESR of 4.0Ω at 100kHz, and an operating temperature range of -55°C to +125°C.

What are the sourcing risks?

As a standard tantalum capacitor, supply is generally stable, but users should ensure the manufacturer's specific derating guidelines are followed to prevent field failures.

What is the pinout of CA45-B-16V-47uF-K?

Use the CA45-B-16V-47uF-K datasheet for the official pinout diagram and pin names. In PartGenie, ask Datasheet AI about CA45-B-16V-47uF-K pinout to locate pins, power rails, and interface signals before layout.
