2. Key Features (From the Table):

️· Inductance Range: From 0.047uH to 220uH
️· Frequency Range: Datasheet indicates testing frequency. Varies significantly (0.796MHz to 100MHz) depending on the inductance value.
️· Rated Current (Isat): 40A to 50A (This value varies significantly between different inductors).
️· Saturation Current (Isat): A measure of how much current the inductor can handle before its inductance drops significantly.

3. Detailed Table of Values (Partial Listing - See the table above for all values):

The table provides the most crucial data:

Part Number	Inductance (uH)	Test Frequency (MHz)	DC Resistance (Ω)	Saturation Current (A)
DR349-1-047	0.047	100	0.30	40
DR349-1-101	0.10	25.2	0.44	450
DR349-1-153	15	2.52	2.8	130
DR349-1-224	220	0.796	21	50

*(And so on...)*

4. Mechanical Details:

️· Units: All dimensions are in millimeters (mm).
️· Tolerance: General tolerance is ±0.1mm.
️· Packaging: 2000 pieces per reel.
️· Non-RoHS Option: If RoHS compliance is not required, replace "DR" with "42" in the part number (e.g., DR349-1-101 becomes 42349-1-101).

Important Notes:

️· Datasheet Age: This datasheet is from 2007. Specifications can change over time. It's crucial to check with Datatronics or a distributor for the most current information if you are planning to use these parts.
️· Saturation Current (Isat): This is a critical parameter. Exceeding the Isat value will cause the inductance to drop significantly, potentially affecting circuit performance.
