Key Definitions:

· Inductance (μH): The inductor's ability to store energy in a magnetic field, measured in microhenries.
· Tolerance (%): The acceptable variation from the nominal inductance value.
· Q (Min.): A measure of the inductor's efficiency. Higher Q values are generally better.
· Test Frequency (MHz): The frequency at which the electrical characteristics are measured.
· SRF (MHz) (Min.): Self-Resonant Frequency – the frequency above which the inductor's impedance rapidly decreases.
· DCR (Ω) (Max.): DC Resistance – the resistance of the inductor when measured with DC current. Lower is better.
· Idc (mA): DC Current – the maximum DC current that can flow through the inductor without causing excessive heating.
· Isat (mA): Saturation Current – the current at which the inductor's magnetic core begins to saturate, causing inductance to drop significantly.

3. Dimensions (mm):

· The document provides a few dimensions (in mm and inches) related to product dimensions. These aren't listed here in detail due to the lack of clarity in the text.

4. Packaging Specifications (Tape and Reel):

· The document describes how these inductors are packaged for automated assembly. Details are provided in mm and inches, covering dimensions like reel diameter, width, and other relevant parameters.

Important Considerations:

· Incomplete Data: The provided document snippet appears to be an excerpt. A full datasheet would contain more detailed specifications.
· Variations: The 9250A series likely has numerous variations not detailed here. Refer to the full Bourns datasheet for complete information.
· Verification: Always verify the suitability of the inductor for the specific application.
