1. When ordering, please specify
packaging
code:
SBU9-6011R0LD
Packaging: D
= 13″ machine-ready reel. EIA-481 embossed plastic
tape 350 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.
2. Inductance tested at 1 kHz, 1 Vrms, 0 Adc on an Agilent/HP 4284A
LCR-meter or equivalent.
3. Current per winding that causes a 40°C rise from 25°C ambient. This
information is for reference only and does not represent absolute maxi-
mum ratings.
4. DCR is specified per winding.
5. Isolation (hipot) measured with 3 mA applied for two seconds.
6. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
