Planar Transformers
| New RoHS part numbers are shown.
Lead was removed from internal parts. The next to the last character is
an L to indicate
RoHS compliance.
(View old data sheet.) |

When
ordering, please specify packaging code: e.g. A0027-ALD |
|
Packaging: |
D = 13" reel, machine-ready
EIA-481 embossed plastic tape (250 parts per full reel).
B = Less than full reel
In tape, but not machine-ready. To have a leader and trailer added ($25 charge), use code letter
D instead. |
