What are the operating temperature ranges this component can handle?

The component can function effectively in temperatures ranging from -40 °C to +105 °C, suitable for both low and high-temperature environments typically found in automotive and industrial applications.

How does the low ESR contribute to its application?

The low equivalent series resistance ensures the capacitor operates with less heat generation and higher efficiency, making it ideal for applications requiring rapid charge and discharge cycles.

What impact does the lifetime rating have on long-term projects?

The 2000-hour lifetime rating indicates durability, making it a reliable choice for long-term projects and reducing the frequency of component replacement in critical systems.

Why is leakage current performance important for this capacitor?

A minimal leakage current of 82.5 μA prevents energy loss in circuits, enhancing overall system efficiency, particularly in battery-powered applications where prolonged operation is essential.
