1. Product Families & Series:

️· DR73: A series of inductors.
️· DR74: Another series of inductors.
️· DR125: Yet another series of inductors.
️· DR127: Yet another series of inductors.

️· DR125:
- Tape and reel packaging: 600 parts per reel, 13" diameter reel.
- Ao=13.0mm. Other dimensions are in a table.
️· DR127:
- Tape and reel packaging: 350 parts per reel, 13" diameter reel.
- Ao is listed in a table
️· Date Codes: `wwllyy` (appears to be a date code).
️· Revision Level: `R`

3. Inductance Characteristics (From Charts):

️· The documents include charts showing "OCL vs. I sat" (Open Circuit Inductance vs. Saturation Current) for each series (DR73, DR74, DR125, DR127). Unfortunately, the specific inductance values aren't directly listed, but the charts illustrate how inductance changes as a percentage of saturation current is applied.
️· Another chart shows "I rms Derating with Core Loss" which appears to correlate current rating with applied Volt-µsecond.

4. Key Parameters (Specific Values are Not Provided, General Information Only):

️· Date Codes & Revision Levels: Identified for each product series.
️· Packaging Quantities: Listed for each series.
️· Operating Frequency: The charts suggest multiple frequencies are used: 200 kHz, 50 kHz, 25 kHz, and 100 kHz

5. Important Notes and Limitations:

️· Missing Specific Inductance Values: While the charts show relationships, they *do not* list the actual inductance values in uH (microHenries) or mH (milliHenries) for each inductor.
️· Chart Interpretation: Understanding the meaning and use of the "OCL vs. I sat" and "I rms Derating with Core Loss" charts would require further expertise.
️· Limited Numerical Data: This is a very visual document and does not provide a great deal of precise numerical information beyond physical dimensions and packaging quantities.
